Don't take this wrong, but you almost sound like Jesse James, but almost look like Kevin Smith (Silent Bob). Really that's kinda legendary lol. And thanks for the vid, sir this is good stuff.
How much old used battery acid do you mix with a concentrated Epsom salt solution. What proportions? Also , once the battery is restored do you leave the Epsom salts and battery solution in the battery and continue to use it like that or does one discard that mixture once battery is fully charged and refill the battery with fresh clean acid?
You all probably dont give a damn but does anybody know a tool to log back into an Instagram account? I stupidly forgot my password. I appreciate any tips you can offer me
The true test is fully charging those batteries, then run them each with e.g. 20 A load (e.g. 4 headlight bulbs in parallel) until the voltage gets down to 11.0 V. You can then compute the total energy released to figure out how much capacity you end up with (basically the longer it takes the better the battery is). Simply being able to load the battery to correct voltage doesn't mean that you can do anything meaningful with the battery. A good car battery is rated between 50-120 Ah as new and if your reconditioned car battery has 2 Ah, it's practically not usable for anything even if it technically still works as perfectly good 2 Ah battery. If you truly just need 2 Ah battery, you should use NiMH or Li-on batteries instead.
@@christianpowerssavesthewor8404 The 12.58 V that you measured is voltage. When you run the starter you need power and for that you need current. The power is literally current multiplied by voltage. The problem is that when battery is bad, the voltage drops rapidly when you try to drain practically any current. A simple test is to measure your battery voltage like you did and then turn on the headlights and turn the ignition to "ON" but not try starting the car. Then measure the battery voltage once per minute. The current needed for the headlights should cause less than 0.01 V drop per minute (but the drop from 12.58 V in this example to headlights on state could be e.g. 0.3 V even with fully functioning battery). The reason for this is that the total energy stored by the battery is limited by the lead surface touching the electrolyte. With damaged battery needing reconditioning the lead surface is damaged and cannot react with the electrolyte over (large?) designed areas. As a result, you get expected voltage but the total energy is very low so draining any current will drain the energy fast out of the battery. Again, energy is literally power multiplied by time. So the above test with headlights on is actually draining energy from the battery and the voltage drop is used as a proxy to estimate the remaining energy in the battery. You can imagine 12.7 V meaning "100%" and about 10.7 V meaning "0%".
@@MikkoRantalainen Thank you for the explanation, I didn't know when he use the boil distill water because it looks to me he still refill the batteries with the same electrolyte removed from them.
@@Brooslinks Oh, you do need to add any lost water but also the part of the lead surfaces that's always submerged get damaged over time. And all the damage there cannot be recovered, no matter what you do and that's the part of the damage I meant above. The parts that are not submerged obviously do nothing for the energy storage so you always want max amount of distilled water in a lead battery.
@@brianlitecky9798 Definitely. Lead batteries were invented around 1859 and the only thing that has changed is purity of the materials used. The less contamination you have, the longer the battery can live. Of course, the body of the battery is nowadays plastic instead of glass for obvious reasons.
Making use of the th-cam.com/users/postUgkxcJ22tnHH9l1vjdIdEIG27iOG55P7LXI8 reconditioning plan, I just saved 2 auto batteries from being completely junked. The guides were very simple to follow. I wish I would have found this years ago! You may use the guide to recondition any battery type
I missed this part also! I'm thinking the epson salt mix is to be flushed out of the battery after a certain amount of time, since we didnt see how he cleans out the corrosion inside. Salt would normally help with something like this. So I'm thinking epson salt solution, let stand for what maybe an hour, then empty. Rinse out the battery, put back the acid and top it off with distilled water (just to under the cap line), then start charging at 200amps for 15 minutes, let stand 30-6-minutes. repeat charging time x3-4, with caps off and ventilated place. When the acid inside starts to boil evenly throughout all cylinders, let stand 1 last hour or so, place caps and done.
Hi all. I'm a mechanic of 27 years. Not everything in this video is correct. If you have an old battery, I can give some simple advice. ( But be assured, the battery will never be like new). You MUST use a "load tester" first, to document the condition of the battery. NOT a Multi Meter, but a LOAD TESTER, that you dial the correct CCA (Cold Cranking Amps) value of the battery as displayed on the label. Once you document the poor condition of the batter, now it's time to recondition it. 1) remove car battery and place is on soft ground such as your lawn. DO NOT open caps or remove any acid yet. 2) Roll the battery around over and over for several minutes. use your boot and kick the battery and make it tumble for a few minutes (this rough contact breaks a lot of the buildup stuck to the plates). 3) Drain all the liquid into a container holding the battery upside down to drain it all. Keep this acid and allow the dirty looking liquid to settle over a few hours, This will take time until the sediments settles to the bottom of your bucket. 4) fill battery with water and repeat process of rolling it after putting caps back on, but DO NOT keep this liquid! instead, dispose of this waste. 5) Once battery is empty again and the captured Acid part 3 has settled and looks clear, carefully pour the acid into another container, leaving lead sludge behind. Finally top up the batter with the clean acid and test the battery on a "load tester".. Yes you can charge it, but prior to doing so, test to see if there is improvement. I recently done this to a Pajero V6 Petrol, that had a dead battery. The Battery bounced back and I got 6 healthy months from it, but eventually it failed to hold a charge. No Epsom salts used in this process, however I am sure that will only improve the condition to perhaps give you as much as 12 months of life out of it, but I cannot verify that as I haven't used salts.
You are correct, The trick is to get the stuff at the bottom broken up and out of the battery. That alone (if it causes bridging) can cause the load tester to give a thumbs down so I am not sure what you would gain by using the load tester first. I am not an expert by any means!
Your a mechanic you know well you should just change the battery come on for god sake all that pissing around and then the thing leaves you down at the worst possible moment. If you have got time to this and earn a living repairing vehicles I tip my hat to you sir. 👍
@@Blaaggarding this information is valuable and important to know and I'll give you an example. I was working as the mechanic on a remote stretch of hi way on the Nullarbor in Australia. Known as the worlds longest straight stretch of road. This road consumes many cars that were not prepared for the drive, and "the Car Graveyard" located 2km from where I was working, was full of perfectly good cars, with damaged engines. One day a Toyota 4X4 with a flat battery that couldn't be charged broke down nearby. The two young backpackers driving it was freaking out as they needed to get back to Perth to fly home in 5 days, Yet where we are, it will take a week to have a replacement battery sent in. This is when that knowledge is valuable as I did it to their car battery and got them to a point where they could start the car with ease each time, and keep going to complete their last 1400km journey. I certainly do not advice you do this trick to a dead battery and then rely on it like these people did to cross central Australia through the desert. But for their needs and the fact they had little option, it worked 100%. But you are correct, ALWAYS replace the battery and be done with it. Peace of mind is important.. Women will NEVER be comfortable with a quick fix like this. They freakout at the very idea that their could still break down. Men, love the challenge hahahaha
My car battery would not hold a charge but the cells tested fine. Put a tbsp of concentrated Epsom salt water in each, trickle charged overnight. Battery lasted fine with no problems and I sold the car three years later. I did not flush the battery or anything. My Dad did his lawn tractor battery the same way - still acting like a normal battery after 4 years.
hi everyone ,if anyone else wants to learn about how to restore a battery try Jons Mender Guide ( search on google ) ? Ive heard some incredible things about it and my mate got excellent results with it.
I have done this just put a half teaspoon of the powder into each cell, The battery looks like it then has a charge but it is only a surface charge. As soon as you put a heavy load on it they fail again.
Thanks! Like anyone researching any subject, I can take parts of your information and combine it with other videos, current knowledge, comments (neg and pos), and find more resources to double check safety and make my own informed decision. Having the guts to show your methods helps us all learn!
That is one of the most wise comments I have ever read on any how to video. thank you for sharing those super positive and wise words about how to look stuff up online. Feels like some people forget that's how you do it lol
I've seen a lot of folks do this battery restoration. I'd love to see a load test on the battery to gauge the capacity. I know it's not going to be perfect like new, just curious what percentage capacity has been recovered?
I have load tested an 800 amp starting battery with a 500 amp loaded tester. I tested the battery several times before recharging it the electrolyte specific gravity test show the acid to be in the high range before recharging.
The open circuit voltage taken on the battery terminal does not indicate any capacity. Volts is potential, capacity is rated in VAh or Volts times Amperes multiplied by the time the load is applied.
Michael Garcia advance Auto was running a deal for every used battery you would trade in they would give you a $20 gift card. It had to be a car battery it could not be a lawnmower battery or a motorcycle battery which my motorcycle battery cost me $140 and did not last a year from advance.
At the beginning of the video when you talked about voltages, a 10.8V battery is a totally dead battery. A fully charged Flooded Lead Acid (FLA) battery reads above 12.6V...sometimes 0.1 or 0.2V higher. And a voltage test indicates the state of charge of a battery but not its health. You need to do a load test and a capacity test, the latter is time consuming and you need to use specialized equipment. Its all fun though.
There's available volts and then there's available amps. You can have 12 volts but little amps and amps is what you need to drive a motor like a starter.
The coating in the battery is sulfur oxide. The metal looking debris is mostly lead and some of the steel grid that is imbedded in the lead plate to hold it all together. The Epson salt trick works 1 time. It somewhat removes the sulfur oxide, but over time will deposit magnesium into the plate.
In my case I have a 12 volt 7.2 Ah battery that although the voltage was at 12 volt when it shorted it did nothing. With the distilled water method it improved a lot only that instead of 7.2 Ah it has 5 amperes, with a no-load voltage of 12.40 volt after a week it remains at 12.00
@@enzovideogames 12v indicated with a volt meter is actually considered less than 6% charged. What most people don't understand, and apparently includes the guy who made this video, is that the percentage of charge for a lead cell automotive/motorcycle battery isn't 100% at 12v and around 10% at 1v, it doesn't work that way. A battery that shows 12.66v with a hand held volt/ohm meter (VOM) is considered 100% charged. A battery that shows 11.89v with a VOM is considered 0% charged. It doesn't work the way that your common sense tells you it will, the percentage of charge doesn't go from 0v indicating 0% charge to 12v indicating a 100% charge. It actually goes from 11.89v considered 0% charge to 12.66v considered 100% charge, 12.24v is actually considered to be only 50% charged, it's not the same as the battery in a cell phone or a laptop, the difference between 0% and 100% charge with lead cell automotive batteries is completely different then a cell phone or a laptop going from 0% to 100%, this is the mistake people make when evaluating the charge condition of a car battery, they compare it in their mind to how their cell phone works but it's completely different. And then you have a load test that simulates cranking on your starter, a car battery can indicate 100% charge, which is 12.66v using a VOM like he is in this video, but you hit the button on a load tester type battery meter and watch the needle dive down into the yellow or red zone on the scale, which means that even though with a VOM it's showing 100% charge it won't pass the load test (which simulates cranking on the starter). Then you have whether or not a battery will hold it's charge after sitting overnight or a few days, you can charge a battery to where it shows 12.66v with a VOM which is 100% charge and leave it sit for 2 days and then put a VOM on it and it'll indicate 12.24v which is 50% charge, meaning that it lost half it's charge sitting for 2 days. It's far more complicated than this guy leads on to be, the only way to properly test an automotive/motorcycle battery is to charge it to where it indicates 100% charge (12.66v) and then hit it with a load tester for 10 seconds and see if the needle stays in the green zone (acceptable) on the scale or drops down into the yellow (meaning weak) zone on the scale or into the red zone of the scale (meaning bad). Hand held VOM meters only tell part of the story, and can't properly evaluate that type of battery, auto parts stores like Autozone usually have a hand held load tester and will gladly walk outside to your car with it and load test the battery for you.
Car battery is 6 x 2.2v cells the two that showed 11.1v were close to 5 x 2.2v = 11v which shows that each battery could have a dead cell. You could prove this if you had charged overnight before ending this video
You failed to load test each of your batteries. A good battery should not drop below 10v while under load and the load should be held for at least 5 secs. A recharged battery will show 12v if tested shortly after a charge if the battery has no dead cells.
That Good, But Have You Done A Load Test On The Batteries To See If They Are Holding There Charge. That Would Be The Real Test To See If Your Reviving The Batteries Really Worked.
Secured Party Hey everyone, the best success that I have had was by following the Magic Mender Wizard (i found it on google) without a doubt the most helpful info that I have ever followed.
I had one that'll charge to 12.7 volts, but after an hour, it'll die to 10.9 volts. Sign of a dead cell. It's dangerous, but you can pop it with a welder sometimes & get the dead cell to take. There's a video on here somewhere where a Mexican guy did it.
@@virginia7125 Very dangerous, when you "cook" a battery like that it makes hydrogen gas which is highly explosive. I had a motorcycle battery blow up in my face like that, it wasn't a car battery but it was a large motorcycle battery, one of the biggest one's ever used and when it blew up it blew an entire section off of it, I'm lucky I still have my face. I was putting it back in the bike after trying something like that and when I was putting the chrome cover back on it the cover touched the positive terminal and sparked, an instant later there was a white flash and the next thing I remember was standing fully upright about 6 feet from the bike with my 2 friends screaming at me but I couldn't hear anything they were saying, because I'd temporarily blown out my hearing. Sometimes in life it just pays to bite the financial bullet and buy a new battery instead of trying these homemade ways of doing things thinking your going to beat the system, you do wind up with a new battery out of it after all.
Hey Man! If Acid Burns Concrete Why Are You Waring Sandals When Your Working On Them. You've Just Showed How Unsafely You To The Ministry Of Labor. That Is An Automatic Fine From The Safety Board.
Your testing is inadequate. The batteries maybe restored to like new. Idk But testing a battery for voltage doesnt represent in anyway what the batter does under load. A big amp draw like a starter might see the battery voltage fall below what is acceptable. Get yourself a load tester and be sure about your findings. Thanks for posting though.
Thanks for the Video clip! Forgive me for butting in, I would appreciate your opinion. Have you ever tried - Lammywalness Trendy Trade Guide (google it)? It is an awesome one off guide for learning how to recondition batteries at home without the normal expense. Ive heard some super things about it and my BF after a lifetime of fighting got excellent results with it.
Battery minimum voltage should be 12.5. They should also be load tested. Hate to be negative, but there is many ways that a battery can fail. As a battery ages the lead decomposes and ends up in the bottom. It belongs on the plates. Even if one can bring it back to life it will usually have low cranking amps or test amps. If the battery gets discharged too many times it can also sulfate.
12.5 volts is the Minimum voltage if the battery is sitting not connected to a charger. It is a static rest voltage. Sometimes the battery will be higher if it is pulled off the charger but it will settle to 12.5 or very slightly above within a few tenths if it is good and all the cells are contributing..
@@CarGroves ive been a master mechanic for 30 years a new Battery isnt fully charged off the shelf and they should charge yo 13.6 and should be load tested with a battery load tester to show they have the proper cranking amps the voltage doesn't mean nothing when it doesn't have the amps to crank it over , and it looses it's voltage the first time under a load.
About 12.74 - 12.6 v volts fully charged battery. Approx 12.40 is 50 % ! Some ecu's go into limp mode as they don't get incoming voltage . Running it should read 14.4 v - 13.7 V approx. Even with lights / heaters on
I'm afraid I don't think your voltage testing is sufficient. Can you not try and measure the voltage under a load.. Even if you connect up a car headlamp bulb, in parallel with the meter leads.. and measure potential across the bulb. \ Proper battery testers have a very low resistance as a shunt with a meter tapped into the shunt. We need to know the Amps, under load, not the unloaded volts..
All you are measuring is Surface Voltage .... most batteries off the charger measure a good voltage... load test it ... you may be really disappointed .
sulphation is the killer, sediment settles to the bottom and shorts out the cells. After bathing the batteries in epson salts( for an extended period), and a thorough flush, use distilled water, and proper amount of sulfuric acid to fill the cells. Don’t use the old electrolyte! You won’t be able to remove all the sulfation between the lead plates, but some more limited service of these used batteries is possible. The capacity and cranking amps will still be compromised. Worthwhile to do IF the batteries were not frozen when discharged, and no bulging or distortion of the lead plates is visible. cheers!
right, of all the assholes in the comments at least one person was able to be objective. if the plates can be cleared and new clean solution added some service can be restored. in my mind, i think this process in combination with a large capacitor for extra cranking capacity is a pretty good solution.(then once failure takes place, find more dead batteries, rinse/repeat but obviously the capacitor would still be good)
Protip, don't dump out sulfuric in to a bucket acid while wearing flipflops and sweat pants. Also have a bucket with a baking soda solution to pour on you if you have a mishap
I\'m not sure but ,if anyone else wants to discover how to recondition lead acid batteries try Jons Mender Guide (just google it ) ? Ive heard some incredible things about it and my friend got great results with it.
Just looked at your video. And I enjoyed watching it! So many of us who owns cars, trucks, motorcycles, etc., for transportation, always thinks that when batteries goes dead, you must always spend more money again to but a new one. I've revived two very old batteries that were dead, by just hooking a 20 watt solar panel directly to them without a solar panel controller. And BOOM! Batteries still works, installed, and started a Dodge Caravan. And the other one is a backup. Someday I'll try your trick, and let you know how it works out!
@@PeterRabbit70I was hoping to also know this. Anyway, my guess is you have to hook up a multimeter and keep checking until you reach the fully-charged voltage. Just a guess, though, as I think I've seen it somewhere.
@ im extremely sorry to have upset you by using the plural of sulphate. I should be purged. This is the part i hate about messages and comments from afar. Id rather discuss things of this matter in person. Its much more fun to meet a snotty little prick face to face then to have them grade your paper and attach little notes to it. Ill try to do better asshole. Look! No plural.
Had a Sears battery that being about a month old died in the middle of a crank. Full voltage yet no amperage would not even activate the solenoid. Took back to Sears told the guy what it did, he put on test bench put big leads on to it. Tested acid with hygrometer- all even- full charge. He hit the amps test and the needle hardly flinched. Threw it in the pile wrote me up for another.
Voltage is one thing but current delivery is another. The amount of amp hours and cranking amps can't be measured with a multimeter and I doubt they would last in operation. Sulphated plates cannot be physically cleaned this way as the plate separators are compressed with the swelling of sulphation, jamming the lead sulphate in place. A tell tale of these un recoverable dead batteries is the bulging of the case, especially at the ends. The epsom salts may clear around the edges of the plates, but you'd be very lucky to get even 10% back.
@@CarGroves two ways they can recondition them, one is to do production line impedance and load test and reject below a certain capacity, the other is to cut around the case just below the seam, lift out the plate assemblies, pressure blast the cell clusters and clean out the sediment cavity then reassemble, ultrasonic welding the plastic back together and adding new acid before charging. Again, they would be graded before reconditioning and any falling below the standard just get recycled. Car batteries are 99.9% recyclable, so they can't lose either way.
@@alasdair4161 a charged battery has the highest acid level. So if you took partially charged lead plates out and pressure blasted them and put them back in considering that they have some of the acid absorbed or converted into them or whatever. If you added full-strength acid after cleaning the plates and putting it back together wouldn't it make the acid level too high?
Alasdair, do they sell lead at the hardware or welding shops? wouldn't it be eaiser for consumers to just buy lead plates and build batteries from scratch?
thanks for sharing your experience sir. but something i missed here regarding the acid is there any acid been added or just solution of distilled water and epsom salt, thanks.
I used a meter on the battery when starting and, unfortunately, the voltage dropped by about 1 volt after i shut the motor off; this indicates that at least one cell in the battery can no longer hold a full charge; and the battery should be fixed or replaced. While waiting to get a new battery at the store, i contacted the dealer and, after the car struggled to start, i managed to get to the service rep at the dealer and they replaced the battery FOC as the car is still under warranty (less than 2 years old). So "13.76 v while the car is running" is *not* an accurate statement. 13.76 v *after the engine is shut off with no voltage drop" is an accurate and true statement.
my take is that you didn't clean the plates with the rinse or the epsom , but with the initial 50A charge. Sulfates are stuck on the plates and you'll need high amps to dissolve those precipitated placks on the plates. Usually a good 10-20 minutes on a 100-200A charge until you see bubbles coming out of the cells will recondition your batteries . I wouldn't advise playing around with highly concentrated sulphuric acid. It's extremely corrosive and dangerous if it gets on the skin , it literally slowly burns away any fabric.
You used way too much Epsom salt. The other thing when you said your four-wheeler wouldn't crank with the battery that had around 10 volts that's because it needs around 12 volts Plus to turn it over to crank it.
The battery I have all the cells had very dark H2SO4 electrolyte fluid from dissolved plates. Flushed and filled with baking soda then drained flushed and replaced with distilled water and Epson salts. Tried to boost with 55 amps to activate the cells for 15 minutes and let it rest for an hour 5 times. Then charged with a smart charger overnight. made absolutely no difference. These techniques only seem to work with batteries that are weak but not with bad plates like mine. It was not keep up with a smart charger every time which might have killed it. If the charge becomes very low the plates seem to dissolve. I have two other batteries that are over 10-15 years old and they are still 100%. Kept them up with smart chargers whenever they got low so the de-sulfating setting could work well.
@@oscarpallaresmedia21 Seems to me if you put 4 lbs of Epsom Salts into a box of lead plates of that size, all you will do is liquify the plates instead of removing the sulfated lead....maybe test that ratio first, on an old lead plate from a useless battery first; or even better, find a junk, useless battery with 1 volt and try that.
I used to make car batteries so I know how they work and i know that you can't bring back to life an old dead battery any more than you can bring back to life an old dead person
You use distilled water for you solution, but you rinse your batterys with a garden hose with city water, then put old acid in. If a battery reads 12v doesnt mean it will crank a car.you need a load tester. Ive done this with batterys before ,sometimes it works. But never for very long. If you live where it gets cold in the winter, it wont work a all.
Currently on the rejuvenation of a battery. I'm noticing how much time,salt,water ,stove,charger , for hours. May or may not work. And how long will it last?
Cheers for the video content! Forgive me for the intrusion, I would love your thoughts. Have you thought about - Rozardner Powerful Battery Reality (google it)? It is a good one off product for learning how to recondition an old battery without the normal expense. Ive heard some unbelievable things about it and my mate after many years got great results with it.
Agree, getting an open circuit voltage is one thing but if there is still plate oxidation on the outside of the plates, you won't be able to pull any decent current. So you have nice voltage restored, but still no ability to crank a motor. He needs to do short circuit current testing
You don't need this epsom salts treatment with a battery which has just gone out like it wont quite crank enough to start your car,, just drain the original acid and rinse out cells with a garden hose , drain them dry, then quick rinse each cell with distilled water.. then go to the parts store and buy some battery acid and fill with fresh acid..put on slow charge until charged.. its a 50/50 chance the batt will be ok. if its just under par then it'll light up easy.
@@stevetilbrook3402 - You can use the old battery acid as long as you 1) let it sit for 24-48 hours so all of the junk settles to the bottom, then 2) move the good clear fluid to another container so you can check the density with a hydrometer, and 3) add more acid or water if the density is off. Once this is done the fluid can be put back in the battery. ***Always keep the fluid in a container that can be capped so there is no evaporation! The epson salt solution would actually be good to use to rinse out the cells as the epson salt will help to remove oxidation from the plates; put it in the cell, move it around some, and let it sit for a few minutes to an hour and then rinse and dry, before adding the acid solution.
@@Rattlerjake1 An older guy at Oreillys who used to do it at a battery refurb shop told me to do it that way and it worked. every three years i replace the acid and it works better afterwood. Thats why i use newer acid its cheap anyway.
@@stevetilbrook3402 - I only mentioned using the old fluid because some people may not be able to get new fluid, or the store is too far; I live in the country and don't drive into town for just one item unless it is a real emergency, I consolidate my trips. You could even use the fluid out of another dead battery if you don't have enough.
@@Rattlerjake1 Yeah I even had an old mustang with a bent valve running on 80mpg by vaporizing the fuel and sending it into the carb throat.. We made a bedini generator once too, its on utube, it producers more power than it uses.. I actually did these things as a lot of people just dismiss stuff if its not spoon fed to them .
@ 08:07 it doesn't make any sense. Didn't say what you put into the batteries, only that you filled them with a turkey baster. How much old battery electrolyte to epsom salt water mixture? Since you didn't test the batteries in your equipment, we can't say they worked. And, if it did work we don't know how you did it.
wouldn't the new mixture have a worse specific gravity than original? SPG fully charged should be about 1.265, dead is about 1.155. Also the lead plates are porous to increase their surface area and increase capacity. This is where sulfation happens, and is very difficult to break down into a solution.
@@gm743633 you're probably more educated about car batteries than the rest of us (no bs). You need to make video restoring batteries and testing their specific gravity to indicate a real restoration - results we can trust using a volt meter and batter SG tester reliably. (Plus a load tester)
Robert Paulson my research started around 2005. the cheapest way I found was to make a “de-sulfinator” circuit. 3mhz 60vdc pulse breaks down the sulfide crystals but takes many months to work and is not a 100% restoration. Best way was to buy a battery acid kit at the auto parts store and change the acid. But those days are gone. That circuit can be used on an old battery. Switching batteries every year you could have two batteries last indefinitely. Keep up the good work and go further my friend.
I don’t believe that you brought these battery’s back to life. You need to do a load test with a Battery Load Tester next. If it passes the load test and shows the CCA (Cold Cranking Amps) to show on the load tester what it shows right on the battery then I will believe you. Sorry. I tried to revive many a battery with Epson Salt and everyone of them failed not one success. It just doesn’t work.
Starting the vehicle puts a load on the battery, hence they were tested and they worked. If you want an indication of battery health you can use the cheap multimeter to measure voltage drop while cranking. If they stay above 10 volts while starting you're in decent shape but if they drop to 7 or 8 it's still a bad battery
Well thats only because you don't understand fully how the process works. there are only a few things that stops energy transfer into lead plates. once you understand this and know how to clean the lead plates to remove the build up you will be able to revive a lead acid battery . I have done this and it has worked for several batteries. some are to far gone because the damage to the plates is too great. but this process works more often than not if you know how to do it...
You’re lucky you can still do that in the USA. Here in the UK all batteries are sealed now. But you’re missing a trick by not settling and then filtering the old battery acid. If you filter the settled acid first through a very fine tea strainer to remove the larger particulate matter, then through coffee filters, you will have a far more extensive process, and end up with a much cleaner, more efficient and longer lasting acid. It’s those floating particles which have come off the plates, that cause the drop in efficiency in batteries.
Car Groves that is of course true. But I’m not talking about metal - as you should already be aware. The corrosion or scale on the lead is correctly termed sulphate. As I believe we have both figured out, it’s this sulphate material that’s clogging up the battery, shorting out the cells and causing it to become inefficient. So it’s the sulphate that’s floating about, not metal. Try thinking before typing a comment based upon assumption and insufficient knowledge. Many of the so-called ‘haters’ on here are actually sharing accurate information. I’m one of them.
There is a guy on the web, that says he can bring back to life any battery, computer drill car batteries, and for 47 dollars he will show you, you ever see this guy?
Your videos completely wrong. The normal voltage on a fully charged battery is 13.78 V nominally. And since the majority of the charge is held at the higher voltage anything under 13 V means your batteries half dead and it goes down exponentially from there so a dead battery is 12volts or less.Further, the question is does your battery retain the charge using the Epson salt solution or does it quickly fail there after. This might work to temporary Lee restore part of the capacity of a battery but it certainly does not rejuvenate 100% or even 50% as you erroneously have concluded. And remember 50% capacity it’s just mostly dead.
Not only that but did they actually store any amps? Amps is what makes a battery work. How many amps? Did they lose their ability to store amps to begin with?
There is an easier method that only requires 15 minutes of 200 cranking amps 5 times, let the battery sit for an hour in between each 15 minutes, it boils all the crap off the inside of the battery and brings it back to life.
This won't remove the contaminants. It's more akin to acid dipping a rusty frame, and letting it sit in it's own oxide juices so they can recombine again. Let your acid cold settle, then decant and filter your acid solution.
Its the cranking amps that start the vehicle So 13V means SQUAT really!!!! if the cranking AMPs are not there. Had a 10yr old battery that would charge to 14.5v but would not start the car because the cracking AMPS was only 120 or so
@@LegendLength it depends. Clean the top of the battery. Use a battery tender to get it to 100 pc. Will take 3,4 days. At 100 pc, take it to auto zone or similar for a conductive battery test. That will tell you how good it is. Oh, if it's a battery that you can add water, top off with distilled and let it sit overnight. Then connect the tender. Do not use a trickle charger. Good luck.
I've done this a few times and what I've come to find out is that you can seem to get them to recharge to a good voltage but the battery never regains it's Cranking amps.
right! That because the plates are sulfated so only the equivalent of a postage stamp surface is available for current draw and the stack of cells are imbalanced (some higher, some lower) In electricity they call that situation "high internal resistance" junk is junk
I tried this on a small sealed led/acid battery and the plates were eventually dissolved into a mass of "black liquid." I guess that you have to get the proper mixture of Epsom's salt into the mixture which I obviously did not have. It would probably be better to desulfate the plates first but this can take a LONG time!
@@CarGroves But..it does not desulfate the plates I would imagine. I could be wrong. They have special electronic devices for that and even with them it takes a LONG time. My plates turned into a "black soup" when I added the Epsom's salt and that was the end of the battery...Lol! Incorrect mixture in my case, l guess?? 😉

Whats the ratio between epsom salt and acid solution may I know? Well if there was that much different in the voltage before -after it just might start a car.

@@CarGroves i haven't tried to revive a battery yet. i think some batteries are good enough to be revived, and some maybe not. if most of your revivals work for you, thats a good thing. a lot of the videos show some kind of revival procedure, and show 12 to 14 volts on their meter, but i don't see them carrying the battery to a vehicle, and starting it up. watching your video, you appear to be honest and truthful about your results.
My Motor Home cabin battery was dead and needed to be replaced when my friend said it could be rebuilt. Got me some Apson Salt, took the battery out and went to work. 45 minutes later the battery was back in the car working perfect. That was 8 months ago.
This article is completely misleading he might have brought the voltage up did you see him try to start a vehicle?no you didn't because they won't they don't have any power in them a battery that reads 12v is practically still flat 12v lead acid batteries charged up will read 13/13.5 or even higher up to 14.4
When you add half old acid and Epson salt solution combined is it suppose to sizzle and can I put charger on while sizzling and if you just use acid and water how much in each cell is it 1/2 and 1/2 what,thanks
Batteries need to be tested under load. Any old car battery will give you 12 volts but the minute you try to draw any sizeable current such as to a starter motor, the voltage will drop due to the internal resistance of the shit battery.
At 6:23 you said you were going to "dump this fluid out" which was what came out of the batteries. At 8:25 you said that you mixed the Epsom Salt/Water solution with the acid....but above you said you dumped the acid. (1). Where did the acid come from did you buy fresh acid/water mix? (2.) Did you pour the acid into the entire gallon of the Epsom salts solution? (3.) If you reused the acid, did you filter it with a cloth or did you pour it unfiltered into the Epsom salts? (4.) Wouldn't that dilute the acid concentration like 1 part acid to 50 parts water? I was anticipating you using the Epsom salts/water solution to clean the inside of the battery but you mixed it with the acid before putting it back in, right? Greatly appreciate your information!
Would have been better if he fully charged and put one in a car I agree. What he did falls in line with the reason they were dead, flushing the battery is a good thing too. I think I would have used full electrolyte after the salt/electrolyte bath but not sure what difference it would make or what the outcome of leaving the Epsom salt solution in them would be or how long they would last.

Thank you
How much old used battery acid do you mix with a concentrated Epsom salt solution. What proportions? Also , once the battery is restored do you leave the Epsom salts and battery solution in the battery and continue to use it like that or does one discard that mixture once battery is fully charged and refill the battery with fresh clean acid?
You all probably dont give a damn but does anybody know a tool to log back into an Instagram account?
I stupidly forgot my password. I appreciate any tips you can offer me
The true test is fully charging those batteries, then run them each with e.g. 20 A load (e.g. 4 headlight bulbs in parallel) until the voltage gets down to 11.0 V. You can then compute the total energy released to figure out how much capacity you end up with (basically the longer it takes the better the battery is). Simply being able to load the battery to correct voltage doesn't mean that you can do anything meaningful with the battery. A good car battery is rated between 50-120 Ah as new and if your reconditioned car battery has 2 Ah, it's practically not usable for anything even if it technically still works as perfectly good 2 Ah battery. If you truly just need 2 Ah battery, you should use NiMH or Li-on batteries instead.
@@christianpowerssavesthewor8404 The 12.58 V that you measured is voltage. When you run the starter you need power and for that you need current. The power is literally current multiplied by voltage.
The problem is that when battery is bad, the voltage drops rapidly when you try to drain practically any current.
A simple test is to measure your battery voltage like you did and then turn on the headlights and turn the ignition to "ON" but not try starting the car.
Then measure the battery voltage once per minute.
The current needed for the headlights should cause less than 0.01 V drop per minute (but the drop from 12.58 V in this example to headlights on state could be e.g. 0.3 V even with fully functioning battery).
The reason for this is that the total energy stored by the battery is limited by the lead surface touching the electrolyte. With damaged battery needing reconditioning the lead surface is damaged and cannot react with the electrolyte over (large?) designed areas.
As a result, you get expected voltage but the total energy is very low so draining any current will drain the energy fast out of the battery.
Again, energy is literally power multiplied by time. So the above test with headlights on is actually draining energy from the battery and the voltage drop is used as a proxy to estimate the remaining energy in the battery.
You can imagine 12.7 V meaning "100%" and about 10.7 V meaning "0%".
@@MikkoRantalainen
Thank you for the explanation, I didn't know when he use the boil distill water because it looks to me he still refill the batteries with the same electrolyte removed from them.
@@Brooslinks Oh, you do need to add any lost water but also the part of the lead surfaces that's always submerged get damaged over time. And all the damage there cannot be recovered, no matter what you do and that's the part of the damage I meant above. The parts that are not submerged obviously do nothing for the energy storage so you always want max amount of distilled water in a lead battery.
Old skool tech
@@brianlitecky9798 Definitely. Lead batteries were invented around 1859 and the only thing that has changed is purity of the materials used. The less contamination you have, the longer the battery can live.
Of course, the body of the battery is nowadays plastic instead of glass for obvious reasons.
Making use of the th-cam.com/users/postUgkxcJ22tnHH9l1vjdIdEIG27iOG55P7LXI8 reconditioning plan, I just saved 2 auto batteries from being completely junked. The guides were very simple to follow. I wish I would have found this years ago! You may use the guide to recondition any battery type
Wait I missed how mmuch battery acid to epsonsalt solution ? 50/50?
About 2 to 1. A gallon is about 8.345 lbs so say 8.35. The bag was 4lbs epsom.salt. so 8.35 ÷ 4 is 2.08. So approx 2 to 1 ratio
How much acid do you put back in before you add Epsom salt solution was kinda vague on that or does it matter thank you
I missed this part also! I'm thinking the epson salt mix is to be flushed out of the battery after a certain amount of time, since we didnt see how he cleans out the corrosion inside. Salt would normally help with something like this. So I'm thinking epson salt solution, let stand for what maybe an hour, then empty. Rinse out the battery, put back the acid and top it off with distilled water (just to under the cap line), then start charging at 200amps for 15 minutes, let stand 30-6-minutes. repeat charging time x3-4, with caps off and ventilated place. When the acid inside starts to boil evenly throughout all cylinders, let stand 1 last hour or so, place caps and done.
@@369SkinneR Thank you!
Hi all. I'm a mechanic of 27 years. Not everything in this video is correct. If you have an old battery, I can give some simple advice. ( But be assured, the battery will never be like new). You MUST use a "load tester" first, to document the condition of the battery. NOT a Multi Meter, but a LOAD TESTER, that you dial the correct CCA (Cold Cranking Amps) value of the battery as displayed on the label. Once you document the poor condition of the batter, now it's time to recondition it. 1) remove car battery and place is on soft ground such as your lawn. DO NOT open caps or remove any acid yet. 2) Roll the battery around over and over for several minutes. use your boot and kick the battery and make it tumble for a few minutes (this rough contact breaks a lot of the buildup stuck to the plates). 3) Drain all the liquid into a container holding the battery upside down to drain it all. Keep this acid and allow the dirty looking liquid to settle over a few hours, This will take time until the sediments settles to the bottom of your bucket. 4) fill battery with water and repeat process of rolling it after putting caps back on, but DO NOT keep this liquid! instead, dispose of this waste. 5) Once battery is empty again and the captured Acid part 3 has settled and looks clear, carefully pour the acid into another container, leaving lead sludge behind. Finally top up the batter with the clean acid and test the battery on a "load tester".. Yes you can charge it, but prior to doing so, test to see if there is improvement. I recently done this to a Pajero V6 Petrol, that had a dead battery. The Battery bounced back and I got 6 healthy months from it, but eventually it failed to hold a charge. No Epsom salts used in this process, however I am sure that will only improve the condition to perhaps give you as much as 12 months of life out of it, but I cannot verify that as I haven't used salts.
You are correct, The trick is to get the stuff at the bottom broken up and out of the battery. That alone (if it causes bridging) can cause the load tester to give a thumbs down so I am not sure what you would gain by using the load tester first. I am not an expert by any means!
Your a mechanic you know well you should just change the battery come on for god sake all that pissing around and then the thing leaves you down at the worst possible moment. If you have got time to this and earn a living repairing vehicles I tip my hat to you sir. 👍
@@Blaaggarding this information is valuable and important to know and I'll give you an example. I was working as the mechanic on a remote stretch of hi way on the Nullarbor in Australia. Known as the worlds longest straight stretch of road. This road consumes many cars that were not prepared for the drive, and "the Car Graveyard" located 2km from where I was working, was full of perfectly good cars, with damaged engines. One day a Toyota 4X4 with a flat battery that couldn't be charged broke down nearby. The two young backpackers driving it was freaking out as they needed to get back to Perth to fly home in 5 days, Yet where we are, it will take a week to have a replacement battery sent in. This is when that knowledge is valuable as I did it to their car battery and got them to a point where they could start the car with ease each time, and keep going to complete their last 1400km journey. I certainly do not advice you do this trick to a dead battery and then rely on it like these people did to cross central Australia through the desert. But for their needs and the fact they had little option, it worked 100%. But you are correct, ALWAYS replace the battery and be done with it. Peace of mind is important.. Women will NEVER be comfortable with a quick fix like this. They freakout at the very idea that their could still break down. Men, love the challenge hahahaha

Why would anyone use that old acid out of the battery why not just put new battery acid in there with the distilled water
Loved that joy u had at the end, starting your ATV. LOL
My car battery would not hold a charge but the cells tested fine. Put a tbsp of concentrated Epsom salt water in each, trickle charged overnight. Battery lasted fine with no problems and I sold the car three years later. I did not flush the battery or anything. My Dad did his lawn tractor battery the same way - still acting like a normal battery after 4 years.
Thanks for the comment!
I think you need to load test, to really know!

I have done this just put a half teaspoon of the powder into each cell, The battery looks like it then has a charge but it is only a surface charge. As soon as you put a heavy load on it they fail again.

That is one of the most wise comments I have ever read on any how to video. thank you for sharing those super positive and wise words about how to look stuff up online. Feels like some people forget that's how you do it lol
I've seen a lot of folks do this battery restoration. I'd love to see a load test on the battery to gauge the capacity. I know it's not going to be perfect like new, just curious what percentage capacity has been recovered?
I have load tested an 800 amp starting battery with a 500 amp loaded tester. I tested the battery several times before recharging it the electrolyte specific gravity test show the acid to be in the high range before recharging.
Video 2
The open circuit voltage taken on the battery terminal does not indicate any capacity. Volts is potential, capacity is rated in VAh or Volts times Amperes multiplied by the time the load is applied.
You should make a video about "how to make distilled water " ;)
Nice video 👌🏼
I've been doing this for 20 years with batteries found on the curb, I haven't bought a battery for 20 years

Volts mean nothing... it's all about the CCA (Cold Cranking Amps) or in other words, how much work the battery can do when fully charged?
Every spring my batteries are dead. Even after using a tender
@@alex124241 check out scotty kilmer on youtube.This guy knows everything about cars
Not true
Totally wrong
No load volts don't mean much, its voltage under load that matters
I don't understand using the Epsom salt since it doesn't neutralize acid like baking soda.
At the beginning of the video when you talked about voltages, a 10.8V battery is a totally dead battery. A fully charged Flooded Lead Acid (FLA) battery reads above 12.6V...sometimes 0.1 or 0.2V higher. And a voltage test indicates the state of charge of a battery but not its health. You need to do a load test and a capacity test, the latter is time consuming and you need to use specialized equipment. Its all fun though.
There's available volts and then there's available amps. You can have 12 volts but little amps and amps is what you need to drive a motor like a starter.
thats what i wanted to see? see them actually cranking an engine over 👍
Thanks for sharing
The coating in the battery is sulfur oxide. The metal looking debris is mostly lead and some of the steel grid that is imbedded in the lead plate to hold it all together. The Epson salt trick works 1 time. It somewhat removes the sulfur oxide, but over time will deposit magnesium into the plate.
If it works, it works.
At either rate, the batteries are worthless to begin with, so if it’ll buy a even another year or two. That’s still a win win…
The battery should be load tested to see if they're any good they can have voltage but still not work.
amps will be low
Watch video 2 on my channel.
In my case I have a 12 volt 7.2 Ah battery that although the voltage was at 12 volt when it shorted it did nothing. With the distilled water method it improved a lot only that instead of 7.2 Ah it has 5 amperes, with a no-load voltage of 12.40 volt after a week it remains at 12.00
@@enzovideogames
12v indicated with a volt meter is actually considered less than 6% charged.
What most people don't understand, and apparently includes the guy who made this video, is that the percentage of charge for a lead cell automotive/motorcycle battery isn't 100% at 12v and around 10% at 1v, it doesn't work that way.
A battery that shows 12.66v with a hand held volt/ohm meter (VOM) is considered 100% charged.
A battery that shows 11.89v with a VOM is considered 0% charged.
It doesn't work the way that your common sense tells you it will, the percentage of charge doesn't go from 0v indicating 0% charge to 12v indicating a 100% charge.
It actually goes from 11.89v considered 0% charge to 12.66v considered 100% charge, 12.24v is actually considered to be only 50% charged, it's not the same as the battery in a cell phone or a laptop, the difference between 0% and 100% charge with lead cell automotive batteries is completely different then a cell phone or a laptop going from 0% to 100%, this is the mistake people make when evaluating the charge condition of a car battery, they compare it in their mind to how their cell phone works but it's completely different.
And then you have a load test that simulates cranking on your starter, a car battery can indicate 100% charge, which is 12.66v using a VOM like he is in this video, but you hit the button on a load tester type battery meter and watch the needle dive down into the yellow or red zone on the scale, which means that even though with a VOM it's showing 100% charge it won't pass the load test (which simulates cranking on the starter).
Then you have whether or not a battery will hold it's charge after sitting overnight or a few days, you can charge a battery to where it shows 12.66v with a VOM which is 100% charge and leave it sit for 2 days and then put a VOM on it and it'll indicate 12.24v which is 50% charge, meaning that it lost half it's charge sitting for 2 days.
It's far more complicated than this guy leads on to be, the only way to properly test an automotive/motorcycle battery is to charge it to where it indicates 100% charge (12.66v) and then hit it with a load tester for 10 seconds and see if the needle stays in the green zone (acceptable) on the scale or drops down into the yellow (meaning weak) zone on the scale or into the red zone of the scale (meaning bad).
Hand held VOM meters only tell part of the story, and can't properly evaluate that type of battery, auto parts stores like Autozone usually have a hand held load tester and will gladly walk outside to your car with it and load test the battery for you.
The battery still drop.
Car battery is 6 x 2.2v cells the two that showed 11.1v were close to 5 x 2.2v = 11v which shows that each battery could have a dead cell. You could prove this if you had charged overnight before ending this video
So for what you mixed the destill3d water and epson salt, when using the OLD used stuff to refill the batteries or did i miss something???
He mixed the distilled water/epson salt solution with the old battery acid, before he put them back in the battery.
You failed to load test each of your batteries. A good battery should not drop below 10v while under load and the load should be held for at least 5 secs. A recharged battery will show 12v if tested shortly after a charge if the battery has no dead cells.
It cld show 13 volts and still fall on it's face with a load tester. Agreed.
Load test completed...

Hey everyone, the best success that I have had was by following the Magic Mender Wizard (i found it on google) without a doubt the most helpful info that I have ever followed.
I had one that'll charge to 12.7 volts, but after an hour, it'll die to 10.9 volts. Sign of a dead cell. It's dangerous, but you can pop it with a welder sometimes & get the dead cell to take. There's a video on here somewhere where a Mexican guy did it.
@@virginia7125
Very dangerous, when you "cook" a battery like that it makes hydrogen gas which is highly explosive.
I had a motorcycle battery blow up in my face like that, it wasn't a car battery but it was a large motorcycle battery, one of the biggest one's ever used and when it blew up it blew an entire section off of it, I'm lucky I still have my face.
I was putting it back in the bike after trying something like that and when I was putting the chrome cover back on it the cover touched the positive terminal and sparked, an instant later there was a white flash and the next thing I remember was standing fully upright about 6 feet from the bike with my 2 friends screaming at me but I couldn't hear anything they were saying, because I'd temporarily blown out my hearing.
Sometimes in life it just pays to bite the financial bullet and buy a new battery instead of trying these homemade ways of doing things thinking your going to beat the system, you do wind up with a new battery out of it after all.
Looks good , interested to see if there is a volt drop over night

The batteries maybe restored to like new. Idk
But testing a battery for voltage doesnt represent in anyway what the batter does under load. A big amp draw like a starter might see the battery voltage fall below what is acceptable. Get yourself a load tester and be sure about your findings. Thanks for posting though.

Battery minimum voltage should be 12.5.
They should also be load tested.
Hate to be negative, but there is many ways that a battery can fail.
As a battery ages the lead decomposes and ends up in the bottom. It belongs on the plates.
Even if one can bring it back to life it will usually have low cranking amps or test amps. If the battery gets discharged too many times it can also sulfate.
K Kenason absolutely! 13.5 is the optimal voltage
12.5 volts is the Minimum voltage if the battery is sitting not connected to a charger.
It is a static rest voltage.
Sometimes the battery will be higher if it is pulled off the charger but it will settle to 12.5 or very slightly above within a few tenths if it is good and all the cells are contributing..

I'm afraid I don't think your voltage testing is sufficient. Can you not try and measure the voltage under a load.. Even if you connect up a car headlamp bulb, in parallel with the meter leads.. and measure potential across the bulb. \
Proper battery testers have a very low resistance as a shunt with a meter tapped into the shunt. We need to know the Amps, under load, not the unloaded volts..
New video with CCA coming soon.
All you are measuring is Surface Voltage .... most batteries off the charger measure a good voltage... load test it ... you may be really disappointed .
sulphation is the killer, sediment settles to the bottom and shorts out the cells. After bathing the batteries in epson salts( for an extended period), and a thorough flush, use distilled water, and proper amount of sulfuric acid to fill the cells. Don’t use the old electrolyte! You won’t be able to remove all the sulfation between the lead plates, but some more limited service of these used batteries is possible. The capacity and cranking amps will still be compromised. Worthwhile to do IF the batteries were not frozen when discharged, and no bulging or distortion of the lead plates is visible. cheers!
Obviously new acid would be ideal. I was just showing how to do it the cheapest way possible. Thanks for watching!
right, of all the assholes in the comments at least one person was able to be objective. if the plates can be cleared and new clean solution added some service can be restored.
in my mind, i think this process in combination with a large capacitor for extra cranking capacity is a pretty good solution.(then once failure takes place, find more dead batteries, rinse/repeat but obviously the capacitor would still be good)
Protip, don't dump out sulfuric in to a bucket acid while wearing flipflops and sweat pants. Also have a bucket with a baking soda solution to pour on you if you have a mishap

The batteries build up sulfates that retard the charging process and ability to hold a charge.
@ im extremely sorry to have upset you by using the plural of sulphate. I should be purged. This is the part i hate about messages and comments from afar. Id rather discuss things of this matter in person. Its much more fun to meet a snotty little prick face to face then to have them grade your paper and attach little notes to it. Ill try to do better asshole. Look! No plural.
This mans got 4 crapped out batteries all in the same time frame? No wonder he’s fed up figuring out how to recondition them lol.
tell us CCA of each battery after charging....getting 12V doesn't mean anything
I'll do a second video soon with CCA
@Brunz M That would be nice to see befores and afters. You'd think that folks would be aware of that since that's what it's all about. ;)

Had a Sears battery that being about a month old died in the middle of a crank. Full voltage yet no amperage would not even activate the solenoid.
Took back to Sears told the guy what it did, he put on test bench put big leads on to it. Tested acid with hygrometer- all even- full charge. He hit the amps test and the needle hardly flinched. Threw it in the pile wrote me up for another.
No, it means SOMETHING, but..I know what you mean. And even the 12V, we need to know if it HELD that 12V.
Voltage is one thing but current delivery is another. The amount of amp hours and cranking amps can't be measured with a multimeter and I doubt they would last
in operation. Sulphated plates cannot be physically cleaned this way as the plate separators are compressed with the swelling of sulphation, jamming the lead sulphate in place.
A tell tale of these un recoverable dead batteries is the bulging of the case, especially at the ends. The epsom salts may clear around the edges of the plates, but you'd be very lucky to get even 10% back.
How does interstate battery sell reconditioned batteries?
@@CarGroves two ways they can recondition them, one is to do production line impedance and load test and reject below a certain capacity, the other is to cut around the case just below the seam, lift out the plate assemblies, pressure blast the cell clusters and clean out the sediment cavity then reassemble, ultrasonic welding the plastic back together and adding new acid before charging. Again, they would be graded before reconditioning and any falling below the standard just get recycled. Car batteries are 99.9% recyclable, so they can't lose either way.
@@alasdair4161 a charged battery has the highest acid level. So if you took partially charged lead plates out and pressure blasted them and put them back in considering that they have some of the acid absorbed or converted into them or whatever. If you added full-strength acid after cleaning the plates and putting it back together wouldn't it make the acid level too high?
th-cam.com/video/RNnSYuTuLk4/w-d-xo.html
Alasdair, do they sell lead at the hardware or welding shops? wouldn't it be eaiser for consumers to just buy lead plates and build batteries from scratch?
thanks for sharing your experience sir. but something i missed here regarding the acid is there any acid been added or just solution of distilled water and epsom salt, thanks.
Did dude really say “neutralize the acid with ... vinegar” 😂😂 you don’t neutralize acids with more acid
Baking soda neutralize acid fast
10.8 v for a 12 v battery is dead
th-cam.com/video/RNnSYuTuLk4/w-d-xo.html
12v for a 12v batter is dead. 13.6v is fully charged.
@@JoeLinux2000 batteries come 12v new, watch my second video
@@JoeLinux2000 13.76 v while the car is running is fully charged.
I used a meter on the battery when starting and, unfortunately, the voltage dropped by about 1 volt after i shut the motor off; this indicates that at least one cell in the battery can no longer hold a full charge; and the battery should be fixed or replaced. While waiting to get a new battery at the store, i contacted the dealer and, after the car struggled to start, i managed to get to the service rep at the dealer and they replaced the battery FOC as the car is still under warranty (less than 2 years old). So "13.76 v while the car is running" is *not* an accurate statement. 13.76 v *after the engine is shut off with no voltage drop" is an accurate and true statement.
Bro is ka cost Kitna ta ?
my take is that you didn't clean the plates with the rinse or the epsom , but with the initial 50A charge. Sulfates are stuck on the plates and you'll need high amps to dissolve those precipitated placks on the plates. Usually a good 10-20 minutes on a 100-200A charge until you see bubbles coming out of the cells will recondition your batteries . I wouldn't advise playing around with highly concentrated sulphuric acid. It's extremely corrosive and dangerous if it gets on the skin , it literally slowly burns away any fabric.
and charging that same acid at 200amps is safe lol, pot meet kettle
You used way too much Epsom salt. The other thing when you said your four-wheeler wouldn't crank with the battery that had around 10 volts that's because it needs around 12 volts Plus to turn it over to crank it.
Thanks for the comment. What ratios would you use?
The battery I have all the cells had very dark H2SO4 electrolyte fluid from dissolved plates. Flushed and filled with baking soda then drained flushed and replaced with distilled water and Epson salts. Tried to boost with 55 amps to activate the cells for 15 minutes and let it rest for an hour 5 times. Then charged with a smart charger overnight. made absolutely no difference. These techniques only seem to work with batteries that are weak but not with bad plates like mine. It was not keep up with a smart charger every time which might have killed it. If the charge becomes very low the plates seem to dissolve.
I have two other batteries that are over 10-15 years old and they are still 100%. Kept them up with smart chargers whenever they got low so the de-sulfating setting could work well.
How much epsom salt do you put in the battery acid before refilling the battery?
None!!
"i've got epsom salt and battery acid mixed together..." Well, what ratio? You skipped the most important part...
All of it
@@CarGroves what the heck kind of an answer is ALL OF IT? Why can't you list all supplies and mix ratios in the notes?
He said on the vid, 4lb bag to 1 gal of water.
@@oscarpallaresmedia21 Seems to me if you put 4 lbs of Epsom Salts into a box of lead plates of that size, all you will do is liquify the plates instead of removing the sulfated lead....maybe test that ratio first, on an old lead plate from a useless battery first; or even better, find a junk, useless battery with 1 volt and try that.
How much acid and how much salt water?
Yeah, make sure you get all of that leaded water back into thesystem
I used to make car batteries so I know how they work and i know that you can't bring back to life an old dead battery any more than you can bring back to life an old dead person
You are wrong
you just dont want peeps to know the battery scam
You use distilled water for you solution, but you rinse your batterys with a garden hose with city water, then put old acid in.
If a battery reads 12v doesnt mean it will crank a car.you need a load tester. Ive done this with batterys before ,sometimes it works. But never for very long. If you live where it gets cold in the winter, it wont work a all.
Thanks for the info
David, for flushing you could use old pond water, it doesn't matter.
12v is basically a dead battery when talking about cranking amps.
Anywhere from 12.7v to 13.1v usually a fully charged battery.
Where I live the way we test when battery getting too old is when it gets cold. It cranks at 30 degrees F will it crank at 10 degrees? Or even zero F.
Currently on the rejuvenation of a battery. I'm noticing how much time,salt,water ,stove,charger , for hours. May or may not work. And how long will it last?
How they hold up when you put a load on the batteries with a load tester
Cheers for the video content! Forgive me for the intrusion, I would love your thoughts. Have you thought about - Rozardner Powerful Battery Reality (google it)? It is a good one off product for learning how to recondition an old battery without the normal expense. Ive heard some unbelievable things about it and my mate after many years got great results with it.
Agree, getting an open circuit voltage is one thing but if there is still plate oxidation on the outside of the plates, you won't be able to pull any decent current. So you have nice voltage restored, but still no ability to crank a motor. He needs to do short circuit current testing
What is the mixture of epsom salt to acid ?
10.8v after charging sounds like it has one bad cell.
So you leave an epsom salt/acid mix in the batteries?
You don't need this epsom salts treatment with a battery which has just gone out like it wont quite crank enough to start your car,, just drain the original acid and rinse out cells with a garden hose , drain them dry, then quick rinse each cell with distilled water.. then go to the parts store and buy some battery acid and fill with fresh acid..put on slow charge until charged.. its a 50/50 chance the batt will be ok. if its just under par then it'll light up easy.
@@stevetilbrook3402 - You can use the old battery acid as long as you 1) let it sit for 24-48 hours so all of the junk settles to the bottom, then 2) move the good clear fluid to another container so you can check the density with a hydrometer, and 3) add more acid or water if the density is off. Once this is done the fluid can be put back in the battery. ***Always keep the fluid in a container that can be capped so there is no evaporation! The epson salt solution would actually be good to use to rinse out the cells as the epson salt will help to remove oxidation from the plates; put it in the cell, move it around some, and let it sit for a few minutes to an hour and then rinse and dry, before adding the acid solution.
@@Rattlerjake1 An older guy at Oreillys who used to do it at a battery refurb shop told me to do it that way and it worked. every three years i replace the acid and it works better afterwood. Thats why i use newer acid its cheap anyway.
@@stevetilbrook3402 - I only mentioned using the old fluid because some people may not be able to get new fluid, or the store is too far; I live in the country and don't drive into town for just one item unless it is a real emergency, I consolidate my trips. You could even use the fluid out of another dead battery if you don't have enough.
@@Rattlerjake1 Yeah I even had an old mustang with a bent valve running on 80mpg by vaporizing the fuel and sending it into the carb throat..

how about a carbon load test
@ 08:07 it doesn't make any sense. Didn't say what you put into the batteries, only that you filled them with a turkey baster. How much old battery electrolyte to epsom salt water mixture? Since you didn't test the batteries in your equipment, we can't say they worked. And, if it did work we don't know how you did it.
50/50
He did test the motorcycle battery. Worked like a charm
wouldn't the new mixture have a worse specific gravity than original? SPG fully charged should be about 1.265, dead is about 1.155. Also the lead plates are porous to increase their surface area and increase capacity. This is where sulfation happens, and is very difficult to break down into a solution.
@@gm743633 you're probably more educated about car batteries than the rest of us (no bs). You need to make video restoring batteries and testing their specific gravity to indicate a real restoration - results we can trust using a volt meter and batter SG tester reliably. (Plus a load tester)
Robert Paulson my research started around 2005. the cheapest way I found was to make a “de-sulfinator” circuit. 3mhz 60vdc pulse breaks down the sulfide crystals but takes many months to work and is not a 100% restoration. Best way was to buy a battery acid kit at the auto parts store and change the acid. But those days are gone. That circuit can be used on an old battery. Switching batteries every year you could have two batteries last indefinitely.
Keep up the good work and go further my friend.
but the voltage is dropping every second. One more day, the car or motorcycle won't start
tick tok
8 D cells will produce 12 volts,won'do anything to start your car!,!!! Load test!!!
I don’t believe that you brought these battery’s back to life. You need to do a load test with a Battery Load Tester next. If it passes the load test and shows the CCA (Cold Cranking Amps) to show on the load tester what it shows right on the battery then I will believe you. Sorry. I tried to revive many a battery with Epson Salt and everyone of them failed not one success. It just doesn’t work.
No shit.
ffas23 It started the vehicles, test passed as far as I’m concerned
@@CarGroves You need a LOAD tester. Even a dead battery can give you 12 volts. Put a LOAD test on it.
Starting the vehicle puts a load on the battery, hence they were tested and they worked. If you want an indication of battery health you can use the cheap multimeter to measure voltage drop while cranking. If they stay above 10 volts while starting you're in decent shape but if they drop to 7 or 8 it's still a bad battery
Well thats only because you don't understand fully how the process works. there are only a few things that stops energy transfer into lead plates. once you understand this and know how to clean the lead plates to remove the build up you will be able to revive a lead acid battery . I have done this and it has worked for several batteries. some are to far gone because the damage to the plates is too great. but this process works more often than not if you know how to do it...

Great info but please do not have Soft drinks out and open toe shoes during these projects.....but overall great job, great information.
You’re lucky you can still do that in the USA. Here in the UK all batteries are sealed now.
But you’re missing a trick by not settling and then filtering the old battery acid. If you filter the settled acid first through a very fine tea strainer to remove the larger particulate matter, then through coffee filters, you will have a far more extensive process, and end up with a much cleaner, more efficient and longer lasting acid.
It’s those floating particles which have come off the plates, that cause the drop in efficiency in batteries.
Metal doesn't float in acid
Car Groves that is of course true. But I’m not talking about metal - as you should already be aware. The corrosion or scale on the lead is correctly termed sulphate. As I believe we have both figured out, it’s this sulphate material that’s clogging up the battery, shorting out the cells and causing it to become inefficient. So it’s the sulphate that’s floating about, not metal.
Try thinking before typing a comment based upon assumption and insufficient knowledge. Many of the so-called ‘haters’ on here are actually sharing accurate information. I’m one of them.
will a coffee filter work ?

Its a scam, just watch a youtube video. Thanks for watching!
Your videos completely wrong. The normal voltage on a fully charged battery is 13.78 V nominally. And since the majority of the charge is held at the higher voltage anything under 13 V means your batteries half dead and it goes down exponentially from there so a dead battery is 12volts or less.Further, the question is does your battery retain the charge using the Epson salt solution or does it quickly fail there after. This might work to temporary Lee restore part of the capacity of a battery but it certainly does not rejuvenate 100% or even 50% as you erroneously have concluded. And remember 50% capacity it’s just mostly dead.
The real question is do they hold a charge?
Yes
th-cam.com/video/RNnSYuTuLk4/w-d-xo.html
Not only that but did they actually store any amps? Amps is what makes a battery work. How many amps? Did they lose their ability to store amps to begin with?
Sorry, but what you are measuring is a float voltage. After a period of drain, they will go low again.
Seemed to work good for me.
th-cam.com/video/RNnSYuTuLk4/w-d-xo.html
Yea
Thank you very much i have safe money. You are a great help .
Why dont they test amperage? Because they wont hold amperage anymore that's why! You need amps to start a car!
yep yep it’s all about the amps. DUH
The amps go up too. Second video coming soon.
There is an easier method that only requires 15 minutes of 200 cranking amps 5 times, let the battery sit for an hour in between each 15 minutes, it boils all the crap off the inside of the battery and brings it back to life.
1000% correct. Only if people knew
What?
WTF?
This won't remove the contaminants. It's more akin to acid dipping a rusty frame, and letting it sit in it's own oxide juices so they can recombine again. Let your acid cold settle, then decant and filter your acid solution.
Maybe not wear flip flops
Checkout your batteries with load hot free load....
Its the cranking amps that start the vehicle So 13V means SQUAT really!!!! if the cranking AMPs are not there.

I think its right say
Volt yes. But no crank amp
Maybe a truck battery will be good for small car
right!
That because the plates are sulfated so only the equivalent of a postage stamp surface is available for current draw
and the stack of cells are imbalanced (some higher, some lower)
In electricity they call that situation "high internal resistance"
junk is junk
I tried this on a small sealed led/acid battery and the plates were eventually dissolved into a mass of "black liquid." I guess that you have to get the proper mixture of Epsom's salt into the mixture which I obviously did not have. It would probably be better to desulfate the plates first but this can take a LONG time!
The whole point of this is to clean the plates.
@@CarGroves But..it does not desulfate the plates I would imagine. I could be wrong. They have special electronic devices for that and even with them it takes a LONG time. My plates turned into a "black soup" when I added the Epsom's salt and that was the end of the battery...Lol! Incorrect mixture in my case, l guess?? 😉
You did not say the mixing solution for the distilled water and mixed acid solution
without load testing those numbers are useless
Not really, it shows that the epson salt cleaned the plates.

Batteries need to be tested under load. Any old car battery will give you 12 volts but the minute you try to draw any sizeable current such as to a starter motor, the voltage will drop due to the internal resistance of the shit battery.
Bad batteries will not show 12v if the plates are bridged. Starting the vehicle is a load test
How much salt solution is mixed with acid?
At 6:23 you said you were going to "dump this fluid out" which was what came out of the batteries. At 8:25 you said that you mixed the Epsom Salt/Water solution with the acid....but above you said you dumped the acid. (1). Where did the acid come from did you buy fresh acid/water mix? (2.) Did you pour the acid into the entire gallon of the Epsom salts solution? (3.) If you reused the acid, did you filter it with a cloth or did you pour it unfiltered into the Epsom salts? (4.) Wouldn't that dilute the acid concentration like 1 part acid to 50 parts water? I was anticipating you using the Epsom salts/water solution to clean the inside of the battery but you mixed it with the acid before putting it back in, right? Greatly appreciate your information!
You know put can have 12.7 VOLTS AND 00.0 amps sooo this really is not all that helpfull.
Would have been better if he fully charged and put one in a car I agree.
What he did falls in line with the reason they were dead, flushing the battery is a good thing too. I think I would have used full electrolyte after the salt/electrolyte bath but not sure what difference it would make or what the outcome of leaving the Epsom salt solution in them would be or how long they would last.
Its actually impossible to have 12.7 volts and 0 amps
