I did this in my electrical mechanic shop class at a skills center in high-school to many batteries. My husband doesn't believe you can do it with a regular car battery because the batteries say on it not to. But I was specifically taught that you can. So I'm sending him this video.
@@roughjeepliving5394fill to just over the lead plates. Make sure it doesn't go below the plates, but I wouldn't fill much higher as it will bubble from the charging and overflow, causing lost battery acid.
Several times I have been reprimanded in the workshop for suggesting doing this for customers to save money. All because the company wants to sell stock and make profits. So its great to see this wealth of knowledge been passed onto the public.
Well said Karl! Thank you so much for watching and sharing, we are glad to help and appreciate your comment, have a great day my friend. mad Mike the hammer SPC
I can’t believe this is my first time hearing about this. I’m kinda stunned in a sense. Definitely going to give this a shot. How often is performing his task necessary?
I used to work at Costco Tire Center and we also sold batteries. By the end of the week we’d have a pallet of old used batteries, we’d shrink wrap the lot and this guy would pick up every week. He said he refurbished batteries and makes a pretty penny. I never knew it was this easy to do this. Outstanding video Karl thank you man
I knew a similar guy. Sadly he passed away quite young. Lead and acid are dangerous on their own. I wouldn't do this indoors without forced ventilation.
Former DODGE mechanic. In 1972 Chrysler came out with a tsb -technical service bulletin on new cars that were sitting a long time and the new batteries would not hold a charge. Take out the battery. Gently bounce the battery on a work bench a few times. Empty and safely dispose of the battery acid. Refill with new acid. Charge normally. Load test and reinstall. Worked 95% of the time and reduced battery warranty claims. Works on old batteries also, except agm and other dry batteries.
Thank you very much you’re exactly correct it works and it works great now you have a spare have a great day thanks for the comment mad Mike Sweet project cars
My grandfather taught me this when I was a wee tot, I musta been too young because I forgot about it until you showed the process, ah the memories unleashed. Life on the Rohnert Park Seed Farm.
The method is quite sound. I'm in my 60's. When I first started driving, a full service Gas Station would not only fill your tank, but also wash your windshield, air your tires, check Oil, Brake Fluid, Trans Fluid and best of all, your battery water level. Batteries lasted the life of the car. Better stations would give the battery a soda bath before checking. (Soda bath is 2 tablespoons of Baking Soda dissolved in 1 gal of water. This is poured over the entire top and down the sides of the battery. It neutralizes the acid that develops as the battery is used. The top of the battery is wiped dry, to ensure none of the soda bath enters the battery when the fill caps are removed.)
I remember all of the full service things as well. It's so pathetic now a lot of places even charge for using the air compressor to add air to your own tires here. Sad, sad world we live in.
My first job at 15 was pumping gas at a full service station in 1963.. we'd jog out to the customer with a smile and give them the full treatment whether it was a buck or a fill. I later graduated to front end work, fixing tires etc. The good old days! 😁
@@sscbkr48 Bet you wouldn't want to be young today. ...sorry, I just had a math teacher in high school who was roughly your age who told us at least twice a year just how much he doesn't envy our generation. I would give an arm and a leg to have been able to get a job at 15.
How does it neutralise the acid on the inside of the battery when this sodamix is poured on the outside and top of the battery? There is thick plastic in between
I remember 20 years ago in Athens, Alabama a man with a small farming tractor emptied out all the water out of his battery added a cup of sulfuric acid and the rest distilled water. ( I honestly do not remember the parts of water to powdered sulfuric acid) Poured it in the battery and charged it. It probably cost him not even a dollar back then and he had a new battery. Absolutely crazy what companies are charging us for simple batteries. Thanks for the video!
Well to be honest, they of course want a profit. But it is quite dangerous for a professional, so you can see the danger for the average idiot. Then we have transport fees and storage fees while the batteries are being refurbished, because "hazardous materials".
I’m a Technician in the shop at a KIA dealership and this does work. A lot of the battery’s I’ve done this to I’ve had to do it more than five times. But if you have the time this does work and you’ll save yourself $$ Thanks for this video.
Worked like a charm, thank you. On mine I had to repeat the process about 12 times, but now a battery that's been dead for maybe 5 years is 100 %. Thanks again.
Excellent!! Thank you for watching and sharing your great results Rock Crusher, we really appreciate it. Some batteries need a little more punch and you did that!! Perfect. Hope you have a nice evening my friend. mad Mike the hammer SPC
I've been doing that since I was a kid when we used to race cars in the '80s we always got a bunch of old batteries from the junkyard and most of them worked again a lot of people don't know about this anymore thanks for the video
100% works. Some batteries may take way longer than others. I'm doing a 12 volt 200 amp hour battery right now for a semi truck. So far has taking me 10 tries with the 15 minutes on 1 hour off. I'm starting to bubble in all cells. Definitely need patience but works. The battery has been sitting for 2 years dead outside
Awesome work michael! Thank you so much for watching and sharing your stupendous results, we truly appreciate it because we KNOW it works as well. Hope you have a great week my friend. mad Mike the hammer SPC
@@completelyafflicted1554I had the same issue, I cycled four times and the cell closest to the negative wasn’t active. I drained the battery fluid and replaced with fresh acid . the cell became active after the first charge
He's giving you a guideline on how to do the process. It may take five times to do it it may take 50 times to do it but it definitely works. Like I said I had two batteries that were outside for 2 years dead. They are both at 13 volts right now charging with my solar system.
Easiest way I think is to get a heavy duty electrical outlet timer. Set for 15 minutes on one hour off. Check every hour or so on the batteries until every cell is boiling. Mine took a day and a half. I do not recommend doing it if you are not going to check on it at night. Just restart in the morning
*UPDATE* My diesel truck has two 12 volt batteries. I tried the 200 amp setting on the first one. It boiled the battery for seconds, then cycled off for a couple minutes. I tried multiple times with same results. I gave up and switched to the 12 volt HI setting and it boiled the battery vigorously. So I used the SPC method over a couple days. Resting the battery for several hours each time. Probably 10 cycles over all and it worked. Battery restored to like new. With the remaining battery, I started off with the 12 HI setting since I knew the 200 amp setting wasn't working, and it wouldn't boil the battery. I tried multiple times same result. So I switched to 200 amp setting and it boiled for a few seconds and cycled. I switched it back to 12 volt HI and low and behold it now boiled vigorously. I continued on with the same process as described above for many cycles and long rest periods. This battery is now testing like new. These are 4 year old batteries in Arizona desert heat. Thanks SPC for showing us the technique.
Good deal azjv you dealt with our video just exactly how we hoped everyone would do you did not give up you tried other methods and it work for you that’s what we do all day long if it doesn’t work we keep trying and adjusting have a great night thanks for the comment Mike
I'll add that the biggest problem we have in a high tech age is that our tools are getting too smart for us to manipulate them into what they think is abuse. Either buy an old school dumb quick-starter, or buy a mid sized welder -- it'll *never* know the difference :-)
I used this method to revive a 8 year old interstate battery for my pickup. Going on its 3rd winter(Minnesota) since the revive.Was going to replace until saw this method.
That's fantastic Dave! SEE our newest Battery Video th-cam.com/video/KzOQH1twpI8/w-d-xo.html Thank you so much for watching and for sharing your results, we truly appreciate it my friend. Hope you have a great day. mad Mike the hammer SPC
@@SweetProjectCars What about all the videos on TH-cam emptying the battery and replacing with the distilled water and Epson salt mix? Would that help this technique any?
I was a little sceptical about this so i had to try it for myself and IT WORKS! I followed it to a "t" as suggested and it definitely made my battery work again. Thanks man,great video!
@@SweetProjectCarsdid the US20 in the link continue to run the entire 15 min? Mine seems to shutoff after about 60 seconds and starts again after 120 seconds. Is this functional correctly?
I did not believe this would work. Too good to be true. But I tried it on two batteries this year. It works like a charm. Thank you so much. This will save me hundreds of dollars.
Thank you for the video, this type of work to keep a battery usable for years is incredibly valuable. You will never learn this from a battery supplier.
I used to charge batteries as a Navy electrician on an old diesel-electric submarine... 504 batteries at once - each one was about 14" X 14" and about 4 feet tall... weight of each battery was 1,000 lbs or so. Trickle charge, deep charge, equalizing charges... good times! Great video! by the way, the bubbles are hydrogen.
This worked 💯 percent top off with distilled water charge at two hundred amps for 15 minutes then let it sit and cool for an hour repeat that cycle several times took my 10 v battery back to a 12-volt battery my only advice would be to turn off battery charger instead of disconnecting terminals cuz the Sparks can and will ignite the hydrogen fumes splashing acid into your eyes so was my personal experience on the third cycle so highly recommend taking advice and not getting acid into your eyes
Glad we could help! Thanks for watching and sharing, anytime you work on your vehicle there's an amount of caution that needs to be taken. We appreciate the input, have a fantastic day my friend. mad Mike
Did I read this right, did you just say you got battery acid in your eyes while doing this? By the way, I always connect a battery charger while unplugged, regardless of whether the battery caps are removed, and then unplug first before disconnecting.
Won't the liquid evaporate ? Should I top off the liquid wth distilled water ? But really , 15 times ? Thats 15 hours waiting plus 15 min. x 15 times ! Thats a lot of time to spend in the garage ! Who has that much free time ? How much is your time worth ? I would rather pay the piper and buy a new battery ! My wife and family think I am watching you-tubes in the garage !
I've followed your method twice now on 2 different batteries, one deep cycle battery, and one regular car battery, it worked amazing! Thank You for this video!!
Glad it helped Cade! That's awesome, watch this as well, th-cam.com/video/VYtkn-N_p4s/w-d-xo.html it's a way faster and better option. Thank you for watching and sharing my friend, it's much appreciated, hope you have a great day. mad Mike the hammer SPC
The bubbling is the gassing phase. This is when the battery is producing hydrogen gas and is at least 80% charged. It's in its most fragile state at this point and there is a risk of losing active material on the plates, but since you're desulfating a battery that most people would scrap, your 15 min cycles at 200 amps shouldn't cause much if any. You'll begin to see cloudy and dark electrolyte when the active material begins to shed. Good video and good tips 👍
Nice video. I have a few questions. After the battery is brought back to life would it be a benefit to dump out the old contaminated liquid, acid, and add new distilled water? Second question, small kid toy 12 volt batteries such as 7 or 9 amh batteries. Suggestions for waking them up? Have a nice day.
Lead acid have around 500charge cycles until they are done. I made a 12v Lto battery for around 120euros has 20000+ cycles holds more charge and its not heavy and has a similar voltage curve as a leadacid, so no special charger needet. And the operation temp is -35to 60 degres celsius. Even those Lto cells wont burn if damaged or overloadet
Great video. When I was a young kid, I had a scrap hauling business. An old farmer neighbor showed me how to do this with older batteries that I would take out of old cars that I would scrap. I had a pallet full and one day he asked me what I was doing with them. I told him that I was making a full pallet to take to the scrap yard to recycle and get money for each pound. He said to forget about that, because he could show me how to make them work again and sell them as working batteries and make more money. He said as long as the casing wasn't cracked or the posts weren't broken, it would work. He did tell me to only use distilled water, like you mentioned. However, I didn't hear you say anything about the fumes and making sure that all of the caps were removed and water was inside the cells Before heating them up. Also, the fumes and being in a well ventilated area is a major safety factor.
In the video he did say to make sure to fill it up with DISTILLED WATER (no minerals or heavy metals in distilled water). and he also said to REMOVE ALL OF THE CAPS. just make sure you let it rest for an hour between like he said as well and don’t get any of the battery acid on you or your clothes or anything. It will burn a hole in your clothes and your flesh. Baking soda and water neutralizes the battery acid so keep both nearby just in case it bubbles over. And protect your eyes and even your whole face by wear protective glasses or a clear face shield in case it splashes. Wear rubber gloves as well and old clothes that you won’t care gets ruined if it does splash onto your clothes. Make sure it doesnt splash on your skin. And don’t put your body or your face directly over the holes in the battery or keep it more than 15 minutes. Batteries can and do explode so use caution and don’t let children get near the battery either. Children are curious and may not be aware of the danger of even touching a battery with bare hands if any acid is on it. I was a mechanic on jet fuel trucks in the Air Force for 9 years but we weren’t allowed to revive old batteries like this. Thanks for the info and keep up the great work!
I know I’m a bit late here but both batteries that I’m wanting to do this on are fairly new and the fluid level is correct in them. Do I leave them be, or do I replace the water that is in them for distilled water.
@@corygoins4187 no dont replace the fluid in the battery just add distilled water as needed because there is a percentage of acid in the water that has to stay in there, only the water evaporates the acid stay in the battery
This is a really practical and money saving video regarding automobiles. Thank you for the video and knowledge. If you have patience a few tools (including sometimes needing to be able to solder) Alternators too can be easily fixed. As 90% of all alternators fail due to faulty brushes. Which is a $5-10 part.
Absolutely Johann!

I am speechless. This really works? I'm still a little bit skeptical because it sounds too good to be true, but if this works it's the single most awesome automotive hack I have seen in many years. Wow... just *WOW.*
OK. Have looked at several ways to fix a battery and this one definitely works! I can get free batteries from our local junkyard where I live in Alaska. I am trying to get enough deep cell batteries to use in case our power goes out since it is locally generated. So far I have done 8 that tested bad under load. All I did was what is said in the video. Don't recommend filling up the water completely until your done because it does book out. Check your batteries every time after you do this because some don't require five times. With the exception of one all have been rejuvenated. The one that did not I am still working on. I am on around the 10th cycle. Only doing it because it seemed to gain a little every time I checked it. It slowly charged to a little at a time to 12 volts. The first several times I checked it it would not hold a load. I just checked it and it is at 12 volts and still reads weak but it actually holds that reading. I am so confident it will eventually read good. I have also done 4 car batteries that checked bad and are now good and hold a load. Thank you for this. The best and easiest video on battery repqair.
Can I do this while battery is in the car connected to the car or do I have to disconnect the battery posts and then do this process 5 times for 15 minutes. Thanks for your time and be appreciated for an answer ASAP. Take care
Disconnect the battery from the car. Although these ‘start’ chargers are designed to get your car quickly started with a flat battery they weren’t designed to do this while connected to the car for 15 mins at a time. You might end up with a fried regulator or something else damaged.
Thanks for the info! I'm 72 and I remember when batteries had caps that allowed easy access to refill the cells with water, but I didn't know exactly how to recharge it. Thanks for the simple, yet valuable information!
Absolutely, it's our pleasure J. E. ! Thank you for watching and commenting, see this update as well th-cam.com/video/VYtkn-N_p4s/w-d-xo.html it has additional helpful information about this process. Have a great day my friend. mad Mike the hammer SPC
Thank you for teaching me this. I live in Arizona and my batteries last on average 2 to 3 years. Having multiple cars bikes and quads means lots of money if you have to replace multiple batteries every other year or so.

The length of battery life is reduced in southern states cause the water boils out of the batteries if you regularly checked the water levels of the batteries you are using
@@robertthegrowguy7115 I live in AZ and battery water level should be checked every 3 months in the spring-fall. Im off-grid on solar. A quality solar charge controller helps also, one that wont boil your batteries.
Hi, I just want to say big thank you for posting this video. I remember when my grandfather was refreshing his car battery. He had two cars purchased brand new at that time. I never saw him buying batteries for car. He did this procedure every spring to refresh batteries from winter “hibernations”
Followed your instructions down to the T. It worked!!! I have several old batteries I will be reviving. Thanks a whole bunch! No more getting screwed over!
Omg people just toss them? My aunt used to buy a new one we thought she was crazy. It's basically jumping a battery and having the alternator run after to put a charge.
I have a 2003 S10 extreme that has not been driven in the winter time,as I’m from Michigan. It was outside until 2017 in winter, at first I would start it on the coldest day and it always started. There was some years I wouldn’t start it at all in winter, and it would always start in the spring like new. Never had a problem with the battery, still starts like new. I contribute it to the insulated battery cover that encased the whole battery. The battery is 20 years old and still starts like new, never ever had to put a charger on it. But I’m glad I came across your channel. Now I know what to do with it if it ever goes bad. Thanks very much for the information on how to rejuvenate batteries.👍
I had several batteries that were weak (ie would not start my diesel tractor even after charging). I tried your method and it worked like a champ. I had another battery that was completely toast (after charging with my "smart" charger, it wouldn't get more than 2 volts). I though it was worth a try. I have cycled it 4 times and now it is up to 12 volts. I think that I will probably cycle it at least 3 more times, but I am sure that it will be good as new. Thanks for the video. It really works.
Awesome WilsonT!! Thank you so much for watching and sharing your fantastic results, we really appreciate it, have a great weekend my friend. mad Mike the hammer SPC
I'm 40 and can remember my dad topping off batteries with distilled water and doing something to bring really old batteries back to life.... I think it was this process. He's getting up in age now and his mind isn't what it once was so i don't bother asking mechanical questions anymore. Thank you for the information, I've got a dead battery in my truck right now and live pretty far from civilization to aquire a new one without paying an arm and a leg ($300+ for a group 78 is outrageously high priced)
This used to be done at the full-service gas stations back in the day as well Dewayne! Watch our update to this process here th-cam.com/video/VYtkn-N_p4s/w-d-xo.html it's our preferred method now and is far more economical if you don't have the required charger. Thank you for the view, hope you have a great day. mad Mike
I don't have a 200 amp charger to try this out. They start at $175 which is more than I pay for batteries with 7 year warranty from a farm implement store. Those seven year batteries last 8-9 years. When they are about six years old and winter is coming on, I buy a new one for my Jeep and put that six year old in one of my several John Deere machines. I trade in the oldest one for the new battery. Starting about 25 years ago I bought the seven year batteries and some have lasted 10 years. None have died before the 9 year mark. That is so nice, I remember years ago the best battery was a five year warranty and they barely made it, sometimes died at 4 and a half. Now, the batteries are way better. I hate to spend that much on a charger when I don't need the 200 amp style. My 20 amp charger does a fine job if I happen to leave lights on or when the JD quit charging its battery. I bought a GOOLOO device in case someone needs a jump. That way I'm not risking my Jeep charging system. Maybe I'll give this a try, I have two batteries in the John Deeres that are approaching the nine year marks. I'll make this video a favorite and if I spring for the 200 amp job, I'll try to remember to come back and share if it worked for me. One important thing you didn't mention was, hold long will the battery be functional after you get it the treatment?
Never mind.......read down previous replies & voila found you had already answered this question. Going to try this and if it works for me, you are a lifesaver!!! Thank you so much
No problem, go ahead and do the process and you will be able to see the results first hand. as you know we do not charge a dime to share our top secret, secret methods. have a great day my friend mad Mike SPC
Sweet Project Cars I see another from Oakcliffpride with a stupid comment to waste your time. I also see the same questions asked over & over. I guess people half ass watch the video & don’t want to take the time to look for the answer because of all the stupid asses that make the comment section so long. Naturally I have to lengthen it by addressing the dumbasses. Haha 😂 😂. Thanks for the great video. I have also seen others using epson salt & distilled water to clean out the batteries of any buildup on the plates. Not all of his batteries showed over 12.2volts after charging though.
Oakcliffpride. Why don’t you just go ahead & make that video for us. I mean you want to see so the only way you will believe is first hand obviously. Plus I wouldn’t try this way & waste your time. Just go buy another one.
@@JBSTOPJBSTOP You bitch about a "dumbass" making a pointless comment by asking "stupid questions" and "making the comment section so long" (despite the amount of comments being one of the most important forms of engagement that directly effects how much YT promotes it), by making two pointless buttsnorkeling comments. There are thousands of these "Renew your car batteries" videos on YT and 99% are shite, so asking for proof of results is hardly a stupid comment.
@@SweetProjectCars The #1 charger in your description I looked in questions on Amazon & the first answer of the first question the guys described this exact method & says this charger turns off after a few minutes on. Thermal protection my guess. He had to set it on 90 minutes to get 15 minute charge. Any input on this or should I buy your second choice.??
There was a battery manufacturer in Sydney Australia (Besco) that used fibreglass envelope style separators for the plates. The lead sediment was contained and never shortened a cell. Those batteries lasted for many years. I have also found the batteries that last have room for cells to expand as they age.
I did this with one of the batteries that still had a little power, and it took about 8 charges to work like he explained it in the video and it did work! I did do it on a complete dead battery that has been sitting for 3 years, but I had no luck with it, yet. I'll keep you all posted.
@@SweetProjectCarsmy charger has a 250 amp charge would that change anything in the process? The water starts boiling within second in all cylinders when charging
I get this video in my recommendations when I just replaced my battery LOL. Funny thing is my last car battery had a warranty of two years, but it made it to 3 years.
?? You say that as if it was made to die at the end of the warranty 🤔 lol Mine actually just died the other day at 37 months with a warranty of 36 months... Hmmm go figure. 🤨
Thank you for this video. This worked for my car battery! Was dead for a year, sitting in my outdoor shed. Used my Associated charger (280 amp) and it charged up using my trickle charger.
Tried this with 200 amps and it really works. My car fired right up with authority. Doing my lawn tractor battery next but with 40 amp since it's so small.
Picked up a New lawn mower battery this last Spring after fiddling around with trying to recover the old battery... Used a Combo of a "dumb" 6amp Charger, a 2/6/12amp "Smart" Charger, a Maintainer Charger, and a "desulfator" device. Guess as mentioned previously I just needed to "have the power". A Manual Charger with a Start Assist might be a good investment/Christmas Gift this year... Considering what I spent on that Lawn Mower Battery a Quality Charger might save me a lot of Money over the next few years.
I used to work in an auto parts store. I would buy cores for 15 bucks and everybody thought I was crazy for not buying new batteries. meanwhile I have a like new battery in all 5 of the cars, atv's and the tractor. that would have cost about 700 bucks!! I did it for 75 bucks. thing is, you do have to use and old school non digital charger cause the new solid state ones suck due to the industry not wanting you to be able to do this, since they lose money.
My charger can only do a 50 amp start but I decided to try it anyway. I had a battery as dead as Lazarus and after this procedure, it gave 4 strong cranks and a start right off the bat! I've yet to see how long it holds out but I must say I definitely wasn't expecting that. Thanks very much!
I’m doing mine right now with a 50 amp engine start feature. I was wondering too if the 50 Amps would be enough. I just started doing it. Do the caps have to be off??
Mike, it worked, it really really worked. I have 7 6 volt batteries in my golf cart that wouldn't hold a charge. I purchased your best battery charger you suggested and began the process. Instead of desulfating each 6 volt deep cycle batteries, I connected two in series to make one 12 volt to save time. The last one I did alone and that worked as well. FYI, if anyone has golf cart batteries this will work for them also.. 7 batteries would have cost me over $1300.00, the charger cost me $277.00, I saved a total of $1023 plus tax.

I have a Interstate workaholic battery in my international tractor for 21 years now and the 2 original batteries in my 2007 silverado duramax for 13 yrs. My secret is I keep a 1amp trickle charger on both vehicles 24/7. The only time I take the chargers off is when I'm actually using the tractor or truck.
I did this by accident because the instruction manual said to leave it on a trickle charge. I got 16 years out of the battery. Pulled it out and did see a lot of sulfication on the + terminal. So maybe hit it with the high current once every couple months as well as the daily trickle charge to keep it topped up
Sweet, I love you guys, these days we all need to make use of older parts. I remember this method from years ago when my shop teacher showed us how to restore a sulfated battery!!! Thank you

Thanks for the video.. Very informative. I recently have been looking at prolonging battery life. I started with protecting the battery from engine heat and been trickle charging the batteries weekly. I had come across people topping up maintenance free batteries and you have taken it a step further. I would consider doing something similar but the maintenance free batteries we get dont have any stickers or plastic cover you can remove to access the individual cells. You would effectively have to dig out the plastic at the top and drill holes to access the cells. At that point i stopped looking as it was a lot of work just to add water to get maybe another 6 months. Now seeing the comments about how much longer people get, i will have to rethink and see if i can find a maintenance free battery that has access to the cells and do the recharge that you have shown.
At least some batteries "hide" the cap covers rather smartly. (Have batteries in my UPS Power Strips that have a Plastic Plate glued down inside a recessed lip making access difficult but not impossible. Plus usually by the time the UPS throws a "replace battery" light it is "cooked"/bone dry and too late to recover... Or maybe not.) Having seen A LOT of scrapped "core exchange" Maintenance Free Batteries at various stores... I've always been curious if many of them could have a second life had its owner just tried to clean the terminals/face... much less checked the water level (most "maintenance-free" seemed to have "removable" caps if someone just had a screwdriver)
@@lgoamity I'd be very careful about trying to recondition a UPS battery. You are talking about sensitive electronics protecting expensive electronics. Do you really want to put a computer at risk to save the $15 - $30 replacement cost of a backup battery?
I just did this with a motorcycle battery. So far it has started right up and worked great. Better then new honestly. Will try again in the morning. Edit: tried it again in the morning and the motorcycle fired right up. Wish I new this years ago. I went through alot of batteries in my life.
The Schumacher SC1309 does a decent job but is a pain to get there. As mentioned here many times, the 'smart' modes in the chargers help from battery damage, but they time out. The SC1309 will give 10 minutes of high power on the 40 Amp/Boost mode, and this is the best mode if the battery holds a good charge and you're trying to clean the plates. Basically i would have to press the Start/Stop button twice every 10 minutes (the charge would drop down to ~13.5V then go up to ~15.5V). (Luckily the charger didn't break after doing this 30 times or so, and i was within warranty period). After 30 minutes of high power charging, I would give it the hour break. I did this on 4 batteries. The 200 Amp mode will only charge with high power if the voltage is low (
Thank you for sharing my friend that’s why we suggest the big charger over all the other ones I’m sure your comment will help many people have a great night Mike sweet project cars oh and wait till you see the video on the update of this video and how well the batteries we did worked

Minuteman you’re very correct I learned this from my grandfather many many many many years ago thanks for sharing have a great day Mike sweet project cars
I’ll be trying this out in the near future with high hopes. I plan to build a battery bank to power my house out of scrapyard junker car batteries. With this method I hope to revive them, then with a windmill or two that I’ve built, I’ll be able to charge the bank and then offset a ton of electricity bill expenses👍🏼👍🏼👍🏼
You need deep cycle batteries for powering things. Regular car batteries are good for a few starts when they have a full charge, but loose amperage quickly as they drain.
Thank you so much!! I can't wait to do this to my car battery. It's brand new but I didn't start the car enough over the winter so it's "bad" now. Hoping this does the trick!

I’m so happy to know this procedure now. I’m clear on everything but when you add the distilled water. You did that first but it was to the other battery and it looked like the one you demonstrated on was low on water so I’m not sure if topping off the water is the first step or the last.

Great video , I don't have that charger but I've learned you can use a welder to do the same thing. Yeah you hook the ground to the ground and the stringer( make sure it's electrode positive) to the positive. Turn up the amps. My welder's is 140 amps DC. This should be interesting I'm going to try it on an old lawn mower battery that's been dead for years.

@@kevinburns7255 Same question... Although I'm more curious about when using a Smaller (say 150A) Charger's Start Function... Or even an old school "dumb" charger (that left unattended could just as easily overcharge/cook a battery) on an "average" car battery.
As I’ve had to do several hands on w/my car, your vid came up and this is priceless for me. I will surely do this before getting a new battery…just have to make sure I have another battery on hand. Thank you so much. 😊

Thanks for the tip, you just saved me $200 on a replacement battery that sat dormant for two years. I used a 160A unit followed by a Optima battery charger over night.
There was an old school battery shop in Fresno that did this . They'd hit it about 500 amps for about 10 minutes (depending on battery size ) and then 20 amps for an hour and then the trickle charger. Old Joe had a heart attack and his family sold it . They just sold new batteries for awhile and now it's gone .
I remember working in a service station when I was younger, and they never sold new batteries. Always would bring the battery back to full charge. Like cutting rotors you buy new ones.
Absolutely charlie! This process is a lost art, no one does this anymore, they just keep buying new and discarding the old when it's not necessary. Thank you for watching and sharing, have a great day my friend. mad Mike the hammer SPC
I’ve usually buy a $39 battery tender trickle charger and keep it on my cars or motorcycle batteries when they are new and I’ve had batteries last me over 10 years without any maintenance.
Wow thanks for this upload. I am always getting ads on how to revive your car battery and, never buy another one again. The thing is they want you to pay for their secret. You shared for free and that earned a subscription!
I wish you would have showed us the batteries actually work/being used afterwards! It leaves alot of doubt for alot of folks who will watch this video. I believe it works and I'll definitely be giving the method a try! Thanks for the video anyways it's awesome!
Would've been kinda cool to see you load test before and after to see the net effect by the numbers. Jealous you have a 200A charger. I only have a 50A but am going to try your tips anyway. Thanks.
First time I've seen your channel...Great video!! Should this be done as routine maintenance every couple of years, or should we wait until the battery shows signs of failing? It gets nasty cold here in the winter, so I'm hoping the idea is to do this as regular maintenance when it's nice outside....and not wait for Ma Nature to turn off the heat!! Keep up the good work.
my car battery is not completely dead, but I had to have it jumped after sitting a couple years and the distilled water is low. can I do this method on this battery?
Fixed my girlfriends battery last night following this method, battery was around 8v, when you tried to crank the cars starter obviously didnt engage and dash goes off (lacking amps and voltage), unfortunately i did not have my load tester available for before and after comparisons. She didnt believe me it could be fixed and was willing to pay 100$ for a replacement. This morning she has gone to work in her own car now and no longer needs to use mine, which i am happy about - battery at 12.8v now even after sitting off charge over night. Thanks mate.
Dude! Okay, I feel like an idiot for not delving into this earlier in my my life as I'm old enough (58) to remember "topping off" batteries with distilled water. However, I didn't know about the reconditioning aspect so better late than never, and I'm going to go give it a go on my John Deere tractor/mower battery that crapped out. I have discovered as a newbie in Arizona that the heat kills pretty much everything which is logical when you think about it, but hey, live and learn. I'll report back in a couple days to probably say the same thing everyone else is saying in response to your video. Thank you for putting your knowledge out there and also adding improvements as you go. I'm excited to try this out and by the way, I'm a woman and like to challenge myself with these types of things and learn how to help myself and not expect others to do it for me or pay greedy manufacturers to sell me something I don't need. God bless you!

So I don't need to replace the battery acid in the battery if it's low just use still water to top it off. I was told that it won't charge without battery acid or if it's low?
Hey SPC, thanks for the vid! I've been watching you for quite some time now and have bought/used many of the products you suggest with really good results. Thank You! This one has me stumped, however! I bought the Associated Equipment battery charger you show as "best". I got it literally just before my battery failed in my truck. I just completed the "15 minutes on and 1 hour off" sequence - 5 times. But, I still have one cell that is not responding - nothing. All of the others are actively boiling. Suggestions??? Thanks!!!
Do the process again, up to 3 more times. If that doesn't you have got a battery that cannot be reconditioned. Thanks for asking. Have a great night my friend. mad Mike the hammer SPC
Interesting timing, I just had a guy come around last week looking for old batteries to refurbish. Gave him the one out of my car which has been sitting for 2 years. I wonder if I could have used your method on it. Also, would this work on a motorcycle battery?

Nice! I left my key on for like 3-4 hours and when I went to start it again after I finally got my ball joints done, it wouldn’t start of course. I let it charge overnight on a 10 amp setting (2 10 and 50 are all it has but it’s free) but it’s still only at around 11-12 Volts. I wanna take the battery out of the vehicle and let it charge until I’m able to grab the jump box from my place of employment that’s very similar to the one you recommend. Maybe I already have some distilled water sitting around from the coolant flush a year ago. Thanks for the great video! There’s a second battery for a different vehicle that’s showing the same behavior, maybe your video will save us hundreds!

I know, I was waiting for when they added the water. He just kinda skipped over that part, after telling everyone to watch very carefully and follow every step. I'm a bit confused as to when the water is added and to what level.

Hey! I'm trying this right now on two batteries with 650 cca and 780 ca. These two batteries are used on a Chevy Silverado 3500 Duramax 6.6 liter diesel. They both started at like 0.01 volts. After round 1 each was about 8 V, Round 2 just over 10V so it is increasing but I noticed the voltage is now slowly dropping, seems to have stabilized about 9 V. So far no boiling/bubbling. Round 3 thru 5 same story. Ok so just completed round 6 and they are finally just starting to bubble!
@@MMGJ10 I tested a battery using a snap on dtac plus. It didn't hold a charge and registered as "bad" with cca of 601/730. Tested after as "good" with a cca of 632/730. The battery works now but I think it is unrealistic to think it will be as "good as new". Also consider I used this method on an "ideal" battery (in vehicle bought new that was only driven 10000 miles in ten years). It has held the charge for a year so far. I would use this method for low cca requirements but not if you need reliable high cca power.
can't wait to try this. it's a great time to do this work before frigid winter weather has a chance to kill the battery. my batteries ALWAYS conk out at 30 and below. one question: how come you don't replace the battery acid instead of using distilled water? doesn't the factory installed battery acid get weaker as the years go by?
Hello Rob, the acid doesn't evaporate like the water, this amzn.to/3gb9Ni0 rehydrates the sulfuric acid. Thanks for watching, have a great day. mad Mike the hammer SPC
I'm going to try this on my 6v golf cart batteries. Should I leave them in series at 12v to charge or charge them individually at 6v? Thanks for the video!
You want to have some water in the battery before charging but you DONT fill it until it's fully charged because water expands as it gets hot and will leak all over.
Water expand wen cold e.g. ice wen in can d air expand .if d battery not fill to specify level it will never full charge. If it is resting on the ground it will never fully charge. .don't believe try . Rest on wood or plastic thicker d beter .💡✔💡
No they want them for the lead they melt them down and restart but there are places that sell refurbished battery's that use a charger that pretty much does this there the batter is still not 100% what they were new but they will keep going for years. Make sure to check acid level and don't run down your battery use them just to start and not sit listen to the radio they can last 15 year.
If I remember back to my science school days, (many years ago) at some point the far distant future, the electrons in the acid will become UN-revivable. That is when you dump out the acid (after charging as best as possible) and replace it with new sulfuric acid and voila, a new battery. Maybe that idea no longer applies with this great method, but who knows, it might. Great video. Thank you. I saw the one with the stick welder too. Awesome.
I did this in my electrical mechanic shop class at a skills center in high-school to many batteries. My husband doesn't believe you can do it with a regular car battery because the batteries say on it not to. But I was specifically taught that you can. So I'm sending him this video.
I love it when a woman gets to teach a know-it-all man something like this!
How much watter do you fill in the holes?
@@roughjeepliving5394 In another video doing the same method, it mentions filling to where the plastic plugs would end.👍
@@roughjeepliving5394fill to just over the lead plates. Make sure it doesn't go below the plates, but I wouldn't fill much higher as it will bubble from the charging and overflow, causing lost battery acid.

He said he refurbished batteries and makes a pretty penny. I never knew it was this easy to do this. Outstanding video Karl thank you man
I knew a similar guy. Sadly he passed away quite young. Lead and acid are dangerous on their own. I wouldn't do this indoors without forced ventilation.

Former DODGE mechanic. In 1972 Chrysler came out with a tsb -technical service bulletin on new cars that were sitting a long time and the new batteries would not hold a charge. Take out the battery. Gently bounce the battery on a work bench a few times. Empty and safely dispose of the battery acid. Refill with new acid. Charge normally. Load test and reinstall. Worked 95% of the time and reduced battery warranty claims. Works on old batteries also, except agm and other dry batteries.
Wish Id have seen this yesterday. I just spent $142.00 on a battery for my grand daughter. I fixed her old battery with this technique. It does work.

Shout out from your southern neighbors just a few miles down the 101 in Petaluma!
The method is quite sound. I'm in my 60's. When I first started driving, a full service Gas Station would not only fill your tank, but also wash your windshield, air your tires, check Oil, Brake Fluid, Trans Fluid and best of all, your battery water level. Batteries lasted the life of the car. Better stations would give the battery a soda bath before checking. (Soda bath is 2 tablespoons of Baking Soda dissolved in 1 gal of water. This is poured over the entire top and down the sides of the battery. It neutralizes the acid that develops as the battery is used. The top of the battery is wiped dry, to ensure none of the soda bath enters the battery when the fill caps are removed.)
Thank you so much for watching and sharing Jim, very interesting. Have a great day my friend. mad Mike the hammer SPC
I remember all of the full service things as well. It's so pathetic now a lot of places even charge for using the air compressor to add air to your own tires here.
Sad, sad world we live in.
My first job at 15 was pumping gas at a full service station in 1963.. we'd jog out to the customer with a smile and give them the full treatment whether it was a buck or a fill. I later graduated to front end work, fixing tires etc. The good old days! 😁
@@sscbkr48 Bet you wouldn't want to be young today.
...sorry, I just had a math teacher in high school who was roughly your age who told us at least twice a year just how much he doesn't envy our generation.
I would give an arm and a leg to have been able to get a job at 15.
How does it neutralise the acid on the inside of the battery when this sodamix is poured on the outside and top of the battery? There is thick plastic in between
I remember 20 years ago in Athens, Alabama a man with a small farming tractor emptied out all the water out of his battery added a cup of sulfuric acid and the rest distilled water. ( I honestly do not remember the parts of water to powdered sulfuric acid) Poured it in the battery and charged it. It probably cost him not even a dollar back then and he had a new battery. Absolutely crazy what companies are charging us for simple batteries. Thanks for the video!

Well to be honest, they of course want a profit. But it is quite dangerous for a professional, so you can see the danger for the average idiot.
Then we have transport fees and storage fees while the batteries are being refurbished, because "hazardous materials".

@@qua7771 200 amps its gonna boil pretty quick
He's giving you a guideline on how to do the process. It may take five times to do it it may take 50 times to do it but it definitely works. Like I said I had two batteries that were outside for 2 years dead. They are both at 13 volts right now charging with my solar system.
Easiest way I think is to get a heavy duty electrical outlet timer. Set for 15 minutes on one hour off. Check every hour or so on the batteries until every cell is boiling. Mine took a day and a half. I do not recommend doing it if you are not going to check on it at night. Just restart in the morning
*UPDATE* My diesel truck has two 12 volt batteries. I tried the 200 amp setting on the first one. It boiled the battery for seconds, then cycled off for a couple minutes. I tried multiple times with same results. I gave up and switched to the 12 volt HI setting and it boiled the battery vigorously. So I used the SPC method over a couple days. Resting the battery for several hours each time. Probably 10 cycles over all and it worked. Battery restored to like new. With the remaining battery, I started off with the 12 HI setting since I knew the 200 amp setting wasn't working, and it wouldn't boil the battery. I tried multiple times same result. So I switched to 200 amp setting and it boiled for a few seconds and cycled. I switched it back to 12 volt HI and low and behold it now boiled vigorously. I continued on with the same process as described above for many cycles and long rest periods. This battery is now testing like new. These are 4 year old batteries in Arizona desert heat. Thanks SPC for showing us the technique.

Did I read this right, did you just say you got battery acid in your eyes while doing this? By the way, I always connect a battery charger while unplugged, regardless of whether the battery caps are removed, and then unplug first before disconnecting.

Who has that much free time ? How much is your time worth ? I would rather pay the piper and buy a new battery ! My wife and family think I am watching you-tubes in the garage !
I think it's only 5 times to repeat. @@triumphmanful
Then there’s me who’s 19 and doesn’t care because he already has lead poisoning from welding and soldering so what is more lead going to do?
I've followed your method twice now on 2 different batteries, one deep cycle battery, and one regular car battery, it worked amazing! Thank You for this video!!
Glad it helped Cade! That's awesome, watch this as well, th-cam.com/video/VYtkn-N_p4s/w-d-xo.html it's a way faster and better option. Thank you for watching and sharing my friend, it's much appreciated, hope you have a great day. mad Mike the hammer SPC
The bubbling is the gassing phase. This is when the battery is producing hydrogen gas and is at least 80% charged. It's in its most fragile state at this point and there is a risk of losing active material on the plates, but since you're desulfating a battery that most people would scrap, your 15 min cycles at 200 amps shouldn't cause much if any. You'll begin to see cloudy and dark electrolyte when the active material begins to shed. Good video and good tips 👍
Thanks for watching and sharing. Have a great day. mad Mike the hammer SPC
Good advice, well demonstrated.
maybe worth mentioning not to smoke and be in a ventilated area during process. Hydrogen gas being highly explosive.
Nice video. I have a few questions. After the battery is brought back to life would it be a benefit to dump out the old contaminated liquid, acid, and add new distilled water?
Second question, small kid toy 12 volt batteries such as 7 or 9 amh batteries. Suggestions for waking them up? Have a nice day.
Lead acid have around 500charge cycles until they are done. I made a 12v Lto battery for around 120euros has 20000+ cycles holds more charge and its not heavy and has a similar voltage curve as a leadacid, so no special charger needet. And the operation temp is -35to 60 degres celsius. Even those Lto cells wont burn if damaged or overloadet
@@nevillecapper6529 if we are being honest, it’s not nearly enough hydrogen to cause an explosion
Great video. When I was a young kid, I had a scrap hauling business. An old farmer neighbor showed me how to do this with older batteries that I would take out of old cars that I would scrap. I had a pallet full and one day he asked me what I was doing with them. I told him that I was making a full pallet to take to the scrap yard to recycle and get money for each pound. He said to forget about that, because he could show me how to make them work again and sell them as working batteries and make more money. He said as long as the casing wasn't cracked or the posts weren't broken, it would work.
He did tell me to only use distilled water, like you mentioned.
However, I didn't hear you say anything about the fumes and making sure that all of the caps were removed and water was inside the cells Before heating them up. Also, the fumes and being in a well ventilated area is a major safety factor.
Thank you for watching and sharing Jeremiah, we really appreciate it. Have a great week my friend. mad Mike the hammer SPC
In the video he did say to make sure to fill it up with DISTILLED WATER (no minerals or heavy metals in distilled water). and he also said to REMOVE ALL OF THE CAPS. just make sure you let it rest for an hour between like he said as well and don’t get any of the battery acid on you or your clothes or anything. It will burn a hole in your clothes and your flesh. Baking soda and water neutralizes the battery acid so keep both nearby just in case it bubbles over. And protect your eyes and even your whole face by wear protective glasses or a clear face shield in case it splashes. Wear rubber gloves as well and old clothes that you won’t care gets ruined if it does splash onto your clothes. Make sure it doesnt splash on your skin. And don’t put your body or your face directly over the holes in the battery or keep it more than 15 minutes. Batteries can and do explode so use caution and don’t let children get near the battery either. Children are curious and may not be aware of the danger of even touching a battery with bare hands if any acid is on it. I was a mechanic on jet fuel trucks in the Air Force for 9 years but we weren’t allowed to revive old batteries like this. Thanks for the info and keep up the great work!
I know I’m a bit late here but both batteries that I’m wanting to do this on are fairly new and the fluid level is correct in them. Do I leave them be, or do I replace the water that is in them for distilled water.
@@corygoins4187 no dont replace the fluid in the battery just add distilled water as needed because there is a percentage of acid in the water that has to stay in there, only the water evaporates the acid stay in the battery
Same method then?
This is a really practical and money saving video regarding automobiles. Thank you for the video and knowledge. If you have patience a few tools (including sometimes needing to be able to solder) Alternators too can be easily fixed. As 90% of all alternators fail due to faulty brushes. Which is a $5-10 part.

I am speechless. This really works? I'm still a little bit skeptical because it sounds too good to be true, but if this works it's the single most awesome automotive hack I have seen in many years. Wow... just *WOW.*
Same here. I'm afraid to try it, because my battery just died today (it's at 10.2v), but I don't have any charger.
OK. Have looked at several ways to fix a battery and this one definitely works! I can get free batteries from our local junkyard where I live in Alaska. I am trying to get enough deep cell batteries to use in case our power goes out since it is locally generated. So far I have done 8 that tested bad under load. All I did was what is said in the video. Don't recommend filling up the water completely until your done because it does book out. Check your batteries every time after you do this because some don't require five times. With the exception of one all have been rejuvenated. The one that did not I am still working on. I am on around the 10th cycle. Only doing it because it seemed to gain a little every time I checked it. It slowly charged to a little at a time to 12 volts. The first several times I checked it it would not hold a load. I just checked it and it is at 12 volts and still reads weak but it actually holds that reading. I am so confident it will eventually read good. I have also done 4 car batteries that checked bad and are now good and hold a load. Thank you for this. The best and easiest video on battery repqair.
Awesome Steve!! Thanks for sharing your great results. Take care. mad Mike the hammer SPC
Can I do this while battery is in the car connected to the car or do I have to disconnect the battery posts and then do this process 5 times for 15 minutes. Thanks for your time and be appreciated for an answer ASAP. Take care
Disconnect the battery from the car. Although these ‘start’ chargers are designed to get your car quickly started with a flat battery they weren’t designed to do this while connected to the car for 15 mins at a time. You might end up with a fried regulator or something else damaged.
The water is no longer distilled but disturbed:) I came here cause I was feeling low and now I'm all perked up again. Excellent video.

Omg people just toss them? My aunt used to buy a new one we thought she was crazy. It's basically jumping a battery and having the alternator run after to put a charge.
Did you use the Associated Equipment US20 charger?
I have a 2003 S10 extreme that has not been driven in the winter time,as I’m from Michigan. It was outside until 2017 in winter, at first I would start it on the coldest day and it always started. There was some years I wouldn’t start it at all in winter, and it would always start in the spring like new. Never had a problem with the battery, still starts like new. I contribute it to the insulated battery cover that encased the whole battery. The battery is 20 years old and still starts like new, never ever had to put a charger on it. But I’m glad I came across your channel. Now I know what to do with it if it ever goes bad. Thanks very much for the information on how to rejuvenate batteries.👍

Would have been nice to see voltage readings before and after "treatment"
Why...interstate battery sells reconditioned batteries that they used this prosses on for decades.
I had several batteries that were weak (ie would not start my diesel tractor even after charging). I tried your method and it worked like a champ. I had another battery that was completely toast (after charging with my "smart" charger, it wouldn't get more than 2 volts). I though it was worth a try. I have cycled it 4 times and now it is up to 12 volts. I think that I will probably cycle it at least 3 more times, but I am sure that it will be good as new. Thanks for the video. It really works.

I'm 40 and can remember my dad topping off batteries with distilled water and doing something to bring really old batteries back to life.... I think it was this process. He's getting up in age now and his mind isn't what it once was so i don't bother asking mechanical questions anymore. Thank you for the information, I've got a dead battery in my truck right now and live pretty far from civilization to aquire a new one without paying an arm and a leg ($300+ for a group 78 is outrageously high priced)

@@SweetProjectCars I actually have a 200a charger already. I've not tried it yet, I'll watch your other video first though.
I don't have a 200 amp charger to try this out.
They start at $175 which is more than I pay for batteries with 7 year warranty from a farm implement store. Those seven year batteries last 8-9 years. When they are about six years old and winter is coming on, I buy a new one for my Jeep and put that six year old in one of my several John Deere machines. I trade in the oldest one for the new battery.
Starting about 25 years ago I bought the seven year batteries and some have lasted 10 years. None have died before the 9 year mark.
That is so nice, I remember years ago the best battery was a five year warranty and they barely made it, sometimes died at 4 and a half. Now, the batteries are way better.
I hate to spend that much on a charger when I don't need the 200 amp style. My 20 amp charger does a fine job if I happen to leave lights on or when the JD quit charging its battery.
I bought a GOOLOO device in case someone needs a jump. That way I'm not risking my Jeep charging system.
Maybe I'll give this a try, I have two batteries in the John Deeres that are approaching the nine year marks. I'll make this video a favorite and if I spring for the 200 amp job, I'll try to remember to come back and share if it worked for me.
One important thing you didn't mention was, hold long will the battery be functional after you get it the treatment?
Never mind.......read down previous replies & voila found you had already answered this question. Going to try this and if it works for me, you are a lifesaver!!! Thank you so much

This sounds crazy, but we used to do this with batteries with my Dad. Worked almost every time. Blew my mind.
There was a battery manufacturer in Sydney Australia (Besco) that used fibreglass envelope style separators for the plates. The lead sediment was contained and never shortened a cell. Those batteries lasted for many years.
I have also found the batteries that last have room for cells to expand as they age.

Thanks for the video.. Very informative. I recently have been looking at prolonging battery life. I started with protecting the battery from engine heat and been trickle charging the batteries weekly. I had come across people topping up maintenance free batteries and you have taken it a step further. I would consider doing something similar but the maintenance free batteries we get dont have any stickers or plastic cover you can remove to access the individual cells. You would effectively have to dig out the plastic at the top and drill holes to access the cells. At that point i stopped looking as it was a lot of work just to add water to get maybe another 6 months. Now seeing the comments about how much longer people get, i will have to rethink and see if i can find a maintenance free battery that has access to the cells and do the recharge that you have shown.
Absolutely mpcp27! Let us know what you come up with! Have a great day! mad Mike SPC
At least some batteries "hide" the cap covers rather smartly. (Have batteries in my UPS Power Strips that have a Plastic Plate glued down inside a recessed lip making access difficult but not impossible. Plus usually by the time the UPS throws a "replace battery" light it is "cooked"/bone dry and too late to recover... Or maybe not.) Having seen A LOT of scrapped "core exchange" Maintenance Free Batteries at various stores... I've always been curious if many of them could have a second life had its owner just tried to clean the terminals/face... much less checked the water level (most "maintenance-free" seemed to have "removable" caps if someone just had a screwdriver)

The Schumacher SC1309 does a decent job but is a pain to get there. As mentioned here many times, the 'smart' modes in the chargers help from battery damage, but they time out. The SC1309 will give 10 minutes of high power on the 40 Amp/Boost mode, and this is the best mode if the battery holds a good charge and you're trying to clean the plates. Basically i would have to press the Start/Stop button twice every 10 minutes (the charge would drop down to ~13.5V then go up to ~15.5V). (Luckily the charger didn't break after doing this 30 times or so, and i was within warranty period). After 30 minutes of high power charging, I would give it the hour break. I did this on 4 batteries.
The 200 Amp mode will only charge with high power if the voltage is low (

Minuteman you’re very correct I learned this from my grandfather many many many many years ago thanks for sharing have a great day Mike sweet project cars
Just told my wife that I leaned this in high school.
The last Minuteman they expect you not to do it (encourage you) by putting a sticker of the fill caps and advertising it as a “maintained free”.
Yep, remember my dad doing this back in the ‘70s when I was a kid.

I’ll be trying this out in the near future with high hopes.
I plan to build a battery bank to power my house out of scrapyard junker car batteries. With this method I hope to revive them, then with a windmill or two that I’ve built, I’ll be able to charge the bank and then offset a ton of electricity bill expenses👍🏼👍🏼👍🏼
Thank you for watching and sharing my friend. Have a great day. mad Mike the hammer SPC
Wtf you have windmills??? Do you have a video??
I want to see that should great a dream come true how sweet.
You need deep cycle batteries for powering things. Regular car batteries are good for a few starts when they have a full charge, but loose amperage quickly as they drain.
My grandpa used to do this to his old pick up. He never would buy a sealed battery.
Thank you so much!! I can't wait to do this to my car battery. It's brand new but I didn't start the car enough over the winter so it's "bad" now. Hoping this does the trick!
Thank you for watching and sharing, also see this update th-cam.com/video/VYtkn-N_p4s/w-d-xo.html it has a lot of helpful information about this process. Have a great day and all the best on your project my friend. mad Mike the hammer SPC
I’m so happy to know this procedure now. I’m clear on everything but when you add the distilled water. You did that first but it was to the other battery and it looked like the one you demonstrated on was low on water so I’m not sure if topping off the water is the first step or the last. Thanks for the valuable knowledge
Yes, then you do it again during the resting times. Thanks for watching. See this video for additional info th-cam.com/video/VYtkn-N_p4s/w-d-xo.html Thank you for watching and asking. Hope you have a great day. mad Mike the hammer SPC
Great video , I don't have that charger but I've learned you can use a welder to do the same thing. Yeah you hook the ground to the ground and the stringer( make sure it's electrode positive) to the positive. Turn up the amps. My welder's is 140 amps DC. This should be interesting I'm going to try it on an old lawn mower battery that's been dead for years.
Watch this th-cam.com/video/VYtkn-N_p4s/w-d-xo.html it's an update to this method, it's a far better option we've found. Thank you for watching and sharing Chilll, have a great day and all the best on your project. mad Mike the hammer SPC
@@SweetProjectCars I already knew about this that's why I posted what I did
Almost every used motorcycle I buy has a dead battery. Been using this method for years.

FS- What do you set your charger at to do these smaller batteries and time ?thank you
@@kevinburns7255 Same question... Although I'm more curious about when using a Smaller (say 150A) Charger's Start Function... Or even an old school "dumb" charger (that left unattended could just as easily overcharge/cook a battery) on an "average" car battery.
@@kevinburns7255 WHAT DO YOU SET YOUR CHARGER AT TO DO THESE SMALLER BATTERIES AND TIME? THANK YOU!
As I’ve had to do several hands on w/my car, your vid came up and this is priceless for me. I will surely do this before getting a new battery…just have to make sure I have another battery on hand. Thank you so much. 😊

Thanks for the tip, you just saved me $200 on a replacement battery that sat dormant for two years. I used a 160A unit followed by a Optima battery charger over night.
Excellent Tony!! Thank you so much for watching and for sharing your results, Great Job my friend. Have a stupendous week. mad Mike the hammer SPC
There was an old school battery shop in Fresno that did this . They'd hit it about 500 amps for about 10 minutes (depending on battery size ) and then 20 amps for an hour and then the trickle charger. Old Joe had a heart attack and his family sold it . They just sold new batteries for awhile and now it's gone .
Cbmech what does a trickle charger do?
California?

Glad you like them! Thank you very much for your view and comment. Hope you have a great day my friend. mad Mike the hammer SPC
I remember working in a service station when I was younger, and they never sold new batteries. Always would bring the battery back to full charge. Like cutting rotors you buy new ones.
Absolutely charlie! This process is a lost art, no one does this anymore, they just keep buying new and discarding the old when it's not necessary. Thank you for watching and sharing, have a great day my friend. mad Mike the hammer SPC
I did this with an ancient batt. Yet it was 20 minutes with a 45 minute break 4x times. It worked too. Just sharing.
Thank you for sharing Paul we appreciate that Mike Sweet project cars
Did you use the Associated Equipment US20 charger?
I’ve usually buy a $39 battery tender trickle charger and keep it on my cars or motorcycle batteries when they are new and I’ve had batteries last me over 10 years without any maintenance.
I trickle charge once a year in the summer and I get the same result.
Wow thanks for this upload. I am always getting ads on how to revive your car battery and, never buy another one again. The thing is they want you to pay for their secret. You shared for free and that earned a subscription!

I wish you would have showed us the batteries actually work/being used afterwards! It leaves alot of doubt for alot of folks who will watch this video. I believe it works and I'll definitely be giving the method a try! Thanks for the video anyways it's awesome!
well when you try it thats your proof and we did do a update video on them working th-cam.com/video/qNPZsP-arm0/w-d-xo.html thanks Mike
Would've been kinda cool to see you load test before and after to see the net effect by the numbers. Jealous you have a 200A charger. I only have a 50A but am going to try your tips anyway. Thanks.
I'm thinking that with a 50amp you will have to let it charge for an hour instead of 15 min.
I was thinking the same thing. The proof is in the test results, before and after.
My 50 amp boils the battery fluid after 3-4 minutes so I think a 200 amp is over kill.
Andrew Buchen - did you do it on a dead battery or a good one? Probably won’t do that so quick on a dead one.
@@AndrewBuchen did it fully charge your battery? I'm just bought a 50amp so i hope it works
First time I've seen your channel...Great video!! Should this be done as routine maintenance every couple of years, or should we wait until the battery shows signs of failing? It gets nasty cold here in the winter, so I'm hoping the idea is to do this as regular maintenance when it's nice outside....and not wait for Ma Nature to turn off the heat!! Keep up the good work.
Scott great to have you with us!!! we do this for most of our customers once every 2 to 3 years have a great day my friend spc mike
my car battery is not completely dead, but I had to have it jumped after sitting a couple years and the distilled water is low. can I do this method on this battery?
Fixed my girlfriends battery last night following this method, battery was around 8v, when you tried to crank the cars starter obviously didnt engage and dash goes off (lacking amps and voltage), unfortunately i did not have my load tester available for before and after comparisons. She didnt believe me it could be fixed and was willing to pay 100$ for a replacement. This morning she has gone to work in her own car now and no longer needs to use mine, which i am happy about - battery at 12.8v now even after sitting off charge over night. Thanks mate.

I only have a 50 amp charger, i wonder if this would still work? Thanks for the video!
IRATA plumber it will, just that it takes 4 times more time on the charger
Dude! Okay, I feel like an idiot for not delving into this earlier in my my life as I'm old enough (58) to remember "topping off" batteries with distilled water. However, I didn't know about the reconditioning aspect so better late than never, and I'm going to go give it a go on my John Deere tractor/mower battery that crapped out. I have discovered as a newbie in Arizona that the heat kills pretty much everything which is logical when you think about it, but hey, live and learn. I'll report back in a couple days to probably say the same thing everyone else is saying in response to your video. Thank you for putting your knowledge out there and also adding improvements as you go. I'm excited to try this out and by the way, I'm a woman and like to challenge myself with these types of things and learn how to help myself and not expect others to do it for me or pay greedy manufacturers to sell me something I don't need. God bless you!

Watch this update too th-cam.com/video/VYtkn-N_p4s/w-d-xo.html it has a lot of helpful information.
So I don't need to replace the battery acid in the battery if it's low just use still water to top it off. I was told that it won't charge without battery acid or if it's low?
Hey SPC, thanks for the vid! I've been watching you for quite some time now and have bought/used many of the products you suggest with really good results. Thank You! This one has me stumped, however! I bought the Associated Equipment battery charger you show as "best". I got it literally just before my battery failed in my truck. I just completed the "15 minutes on and 1 hour off" sequence - 5 times. But, I still have one cell that is not responding - nothing. All of the others are actively boiling. Suggestions??? Thanks!!!
Do the process again, up to 3 more times. If that doesn't you have got a battery that cannot be reconditioned. Thanks for asking. Have a great night my friend. mad Mike the hammer SPC
@@SweetProjectCars Awesome! Will do! Thanks for your reply, Mike. You're one cool dude...
@@harrley Greetings, did you manage to recover the dead cell and continue with the process?
Interesting timing, I just had a guy come around last week looking for old batteries to refurbish. Gave him the one out of my car which has been sitting for 2 years. I wonder if I could have used your method on it. Also, would this work on a motorcycle battery?
watched lots of videos, THIS is by far the best, best explained and it made absolutely sense. Now i have to find a 200Amp Charger here in Thailand.

@@SweetProjectCarsHi mate, what's the voltage range for 200A needed?
Nice! I left my key on for like 3-4 hours and when I went to start it again after I finally got my ball joints done, it wouldn’t start of course. I let it charge overnight on a 10 amp setting (2 10 and 50 are all it has but it’s free) but it’s still only at around 11-12 Volts. I wanna take the battery out of the vehicle and let it charge until I’m able to grab the jump box from my place of employment that’s very similar to the one you recommend. Maybe I already have some distilled water sitting around from the coolant flush a year ago. Thanks for the great video!
There’s a second battery for a different vehicle that’s showing the same behavior, maybe your video will save us hundreds!
Be sure to watch our update to this process here th-cam.com/video/LMulvB6TtQA/w-d-xo.html & th-cam.com/video/1z_f2Wen_UI/w-d-xo.html it works way better and is far more economical if you don't have the required charger. Thanks for watching, have a fantastic day. mad Mike & team
hey friend, didn’t see on the video that you refilled it with distilled water so I take, you refilled it first before the charging correct?
always make sure there is enough water to cover the cell first. if its too low the cell will overheat.
I know, I was waiting for when they added the water. He just kinda skipped over that part, after telling everyone to watch very carefully and follow every step. I'm a bit confused as to when the water is added and to what level.
Wondering the same. I suppose you need to MAKE SURE you fill each chamber with distilled water first or you will do more damage than good?????
You always charge the battery fully before you add any water
I was just about to ask the same thing. I think so yeah???
I faintly remember my electronics instructor at UTI telling me about this. I never repeated this work in the dealership I worked at because... well you know. We need to sell moooor parts. I am going to try this on my semi truck's EIGHT batteries. This is gunna save me around $3500 in parts!

What kinda batteries are you buying and what truck takes 8 batteries I know my mack 10 wheel only has 3 and it cost me $487.50 about a month ago $3500 wow I will sell you 8 for 2k with free delivery
Hey! I'm trying this right now on two batteries with 650 cca and 780 ca. These two batteries are used on a Chevy Silverado 3500 Duramax 6.6 liter diesel. They both started at like 0.01 volts. After round 1 each was about 8 V, Round 2 just over 10V so it is increasing but I noticed the voltage is now slowly dropping, seems to have stabilized about 9 V. So far no boiling/bubbling. Round 3 thru 5 same story. Ok so just completed round 6 and they are finally just starting to bubble!
Thanks for sharing your progress, keep it up, you will love the results. Have a great day my friend. mad Mike the hammer SPC
Did you get them fully charged? Still going strong? Just curios
@@MMGJ10 I tested a battery using a snap on dtac plus. It didn't hold a charge and registered as "bad" with cca of 601/730. Tested after as "good" with a cca of 632/730. The battery works now but I think it is unrealistic to think it will be as "good as new". Also consider I used this method on an "ideal" battery (in vehicle bought new that was only driven 10000 miles in ten years). It has held the charge for a year so far. I would use this method for low cca requirements but not if you need reliable high cca power.
can't wait to try this. it's a great time to do this work before frigid winter weather has a chance to kill the battery. my batteries ALWAYS conk out at 30 and below. one question: how come you don't replace the battery acid instead of using distilled water? doesn't the factory installed battery acid get weaker as the years go by?
Hello Rob, the acid doesn't evaporate like the water, this amzn.to/3gb9Ni0 rehydrates the sulfuric acid. Thanks for watching, have a great day. mad Mike the hammer SPC
@@SweetProjectCars tx!
I'm going to try this on my 6v golf cart batteries. Should I leave them in series at 12v to charge or charge them individually at 6v? Thanks for the video!
Thanks! Cut the charge time in half for those batteries. Have a great day. mad Mike the hammer SPC
You want to have some water in the battery before charging but you DONT fill it until it's fully charged because water expands as it gets hot and will leak all over.
The water on my planet expands when it freezes. Not when it gets hot.
@@mrdad1541 what
It evaporates with heat. Doesn't expand
Water expand wen cold e.g. ice wen in can d air expand .if d battery not fill to specify level it will never full charge. If it is resting on the ground it will never fully charge. .don't believe try . Rest on wood or plastic thicker d beter .💡✔💡
@@mrdad1541 go back to school...how do you think steam engines work...duh
So this why they tell ya to bring your old one in when you buy a new one 🤑🤔
Exactly. Or pay double price:)
Yup. The core is still good, hence "core charge"
Copper block inside
No copper block. it's lead block.
No they want them for the lead they melt them down and restart but there are places that sell refurbished battery's that use a charger that pretty much does this there the batter is still not 100% what they were new but they will keep going for years. Make sure to check acid level and don't run down your battery use them just to start and not sit listen to the radio they can last 15 year.
If I remember back to my science school days, (many years ago) at some point the far distant future, the electrons in the acid will become UN-revivable. That is when you dump out the acid (after charging as best as possible) and replace it with new sulfuric acid and voila, a new battery. Maybe that idea no longer applies with this great method, but who knows, it might. Great video. Thank you. I saw the one with the stick welder too. Awesome.
Thanks for watching and sharing your knowledge, we really appreciate it, hope you have a great week my friend. mad Mike & team
Great tutorial! Anyone know where the scale goes? Does it settle or evaporate?
It returns into the acid. Sulfate is a chemical compound. You are un compounding it
