Whoa!!!! Dude. Thank you. I'm a retired electrician and I had no idea that one could check each cell on a lead acid battery by sticking a probe into the individual opening. Wow. Thanks. I'm 63 and still learning.
I'm a retired commercial electrician as well, and still learning myself. Do you miss the trade? I sure do. My body gave out before it's time. Too many injuries. Take care
you can check your engine coolant by opening the radiator cap, and put the negative probe in the coolant, and then put the positive probe on the pos terminal of the battery! if your coolant is old the corrosion inhibitors break down and the coolant will pass current. i forget what the cutoff is but if the voltage is above a certain level it means your coolant needs to be flushed. i think it might be like 1.7 volts idk it can be found online. also i might have gotten the polarity wrong but it will just read negative on a dmm.
I have 2 6V 1.2ah batteries from 2007. They were empty so I filled them with distilled water and charger as you said. Charger says they are charging properly. I used a 3cc with needle to fill with. Worked beautifully. Took a lot of water😱😱 Thank you and wish me luck.😅. I
Thanks! Was gonna toss out some UPS batteries but after watching your video I decided to pop them open and see if they had just gone dry. Sure enough, they had gone dry. Refilled them and put the on charge and they are in perfect condition again. Saved me $65 .
Thanks for the video! I had a replacement battery ready to be purchased, saw this video and fixed mine. It was bone dry, added about 3ml to the first cell and got about 2ml in the other 5. Charged it for a couple of hours and now it starts my generator with no problem.
Clear and well-edited video. And thanks for not adding music. One correction, the line voltage in the U.S. is 120v. (Many people still call it 110, but it's been 120 since 1967. I'm sure you know this, but since this is an instructional video....)
This is Killer! I was recently given a diehard jump pack, the previous owner said it wouldn't charge. I'm going to give this a shot. Thanks a ton for such useful and clear information.
Hey. I know this was a while back ago, but I have a similar problem and just came across this video. So did you have any luck with this? Thanks in advance
Mikey ! You are a diamond. I have removed batteries from a back up power supply and now thanks to you I'm going to get them going again if as you say they might recover... Well done... I appreciate it.
I have a 12-10H battery (4 of them), I was using for a 48 Volt lawn mower. Long story short, I re-purposing them for a camping lantern and didn't realize, after an hour, one was dropping to 10.4 Volts powering 400 mA of LEDs. I saw this and a few others and added 50-mL of water to each cell. After one overnight charge 2 hours into the discharge, it still measures 12.8 Volts. Wow what a difference. I'll be adding more for this next charge cycle, but not going to over fill like in this video.
There are several components to battery reconditioning. One plan I discovered that successfully combines these is the Magic Mender Wizard (check it out on google) definately the most helpful course that I have ever heard of. look at this amazing website.
To restrict any spitting of fluids which may occur, simply position your lever, then put a rag over, so you’re sort of working blind. This method can also work in engineering, if you’re removing fasteners that may be sprung or clipped in some manner, a little awkward at times, but easier than looking for that clip that has just been projected fifty feet across the workshop. Eye protection too, don’t forget that.
You would not have pressure in there. These caps are one way valves that relieve any internal pressure during charging but otherwise create a seal. Also known as a 'Valve regulated sealed lead acid battery'. A 12v battery with less than 1v at the terminals that's been sitting around for 4 years will be very difficult if not impossible to recover to a good enough internal resistance by just adding water. There will be thick level 3 sulfate bonds on the plates. Terminal voltage is one thing, let's see you draw some current out of this :) I'm also not sure why you think you would blow a connection between two cells by attempting to charge without adding water?
I know this is old, but I will say this. There was never "water" in the battery to begin with. The acid is absorbed when the battery is manufactured, like M0UKD was saying, they are Valve Regulated. They are sealed from the factory and do not require any acid/water to be put in. simply put, after 4-6 years, its best to just replace it.
Please use distilled water to refurbish the batteries, makes it easier to recycle and they last longer. You can use oil, water or label remover to get rid of the brown tape.
@@chrishayes5755 No. The minerals in tap water can increase both sedimentation and stratification in the battery, and they dilute the electrolyte [in deep cycle batteries].
I have a 12 volt Lead Acid Battery . I have charged it a very long time with Schumacher changer with 1.5 amp It is still only 6 volt in the battery. Why?
So use rainwater, but if it’s not raining water purified, water is fine tapwater distilled water. I’ve always used distilled water in my car batteries. If you do not have distilled water available is bottled water acceptable or should you only use distilled water or rainwater?
Use compressed air to clean the inside of the battery, as opening the caps of the cells would let the junk into the cells. Hold the caps down with your thumb so that the rush of the air will not unseat them. A old toothbrush could be used to brush any gunk away from the cell openings before you remove the caps. Clean each cell thoroughly.
Thanks Rick..The jumping about should be reduced greatly once the cells are refilled and the charger has a few hours. Since you might have been charging them dry be sure and do the cell check with a voltmeter and confirm all the cells are still giving roughly +2v up from the previous.
I know this video is 10+ years old but thanks for that valuable info in 2023! I'm looking to restore my Cyberpower UPS Backup batteries that are SLA. BTW, what voltage are you recharging at, 60 volts DC? WoW!
Hey Mikey, do you have the schematic for dat pimp charger, and why does it charge at such high voltages, I wouldn't think that was good for the battery. very good thumbs up!!
Please I am trying to understand he used only rain water, which he poured into the battery containers, I have seen other videos with stated battery acid to be used. Is this water method right ? Also if I don't have a pimp charger, can I just place it back in the UPS to charge ?
wow. I haven't seen a Casio calculator watch since I was in 2nd grade. my friend freaked out when he realized he'd dropped it in the garbage one day and spent like half hour digging through old hot dogs and ketchup to get it back; a memorable moment.
There are a few things for battery reconditioning never attempt to do this unless you know what you are doing - the acid can burn you check the voltage first - there may be a dead cell which would waste your time. Check the battery fluid. Try to fully charge the battery. (I learned about these and more on Jons mender guide website )
It`s surprising how easy this reconditioning steps are t.co/Folp6e7Dkc ! My auto batteries, cellphone battery, drill battery, camera battery, along with other forms of batteries are all repaired and useful again! Since starting this program I have ended up saving over $ 400 on batteries!?
The only thing that worried me was when he said he was going to sell it. It's not going to have a long life, it was obviously thrown away for a good reason. I've done this trick myself and the batteries quickly lost capacity. By the way, I was told that top plate is purposely easy to prise off because if the battery has to vent it'll blow those rubber seals and also blow that plate off rather than blow the battery apart. Overusing epoxy or gorilla glue may negate that safety feature. Not that I'd like to be around if it did blow.
If you will be using the device daily, even a worn battery can last a long time, despite it discharging rapidly. When I was 18, my car sat for a month with a six year old battery and it was completely dead, or so I thought, My neighbor did some sort of procedure like this, and brought it up to full charge. I would use that same battery all through the winter, driving my car for half an hour twice or more each day, to school or work and back home. When I let it sit for several weeks over the summer, it died again. Rather than go through the procedure again and risk getting stuck, I asked for, and got, a new battery for my birthday. But it showed me that even batteries on the verge of death can sometimes be kept alive with frequent recharging cycles.
I have love and respect for you in my heart. You are one of my teachers no doubt. When I saw so good result, there was your face in front of my eyes that I saw in your video. It is due to me to tell you honestly about my success that is because of you. Thanks.
Old 64 goat, I am 67 and I have recovered many batteries. but not all of them. I add distilled water from the grocery store at $0.75 per gallon and a gallon lasts me several years. (Rain water has some dissolved minerals from running down the roof and in the air it picks up CO2 and becomes mild carbolic acid so distilled water is the best! ) The sealed battery he is working on is a valve regulated not a gel cell and many are in use if the battery is not too dry the gel will absorb the water.
Hi? Good day. I would like to ask if should i throw the old water from my battery and put a distilled water with salt. Or i keep them as is and just add the distilled water and salt? Thank you in advance, god bless
Comments included this "Iron Out" product and dumping all fluids and replacing with distilled water. Why were you not using new battery acid instead of water? I have no experience with these small batteries but lots with big batt for electric warehouse equipment. We would remove those cells gently wash off the sulfation and clean out the case. As long as the plates were okay and the sulfation was no longer present we would refill with new battery acid, ck the specific gravity of the liquid and recharge like a new battery.
JM these are batteries that are in metal cases with individual cells that are sealed in with an asphalt product. These batteries weigh anywhere from 2 to 5,000 lbs. depending on the equipment and voltage, amperage requirement. We would remove the inner cell connectors and pull the non-performing cell completely out of the case. We then cleaned the cell with baking soda and water and plain water under no pressure greater than what you got from a hose. We vacuum out and cleaned the case with the same solution. After a thorough drying we reassembled the cell in the battery case. We also had floor drains in our battery room where all effluent went into a concrete vault. We had it pumped as necessary by an environmentally approved company. I hope I have answered your question. The battery companies are building these batteries (the individual cells in plastic now) which makes this type of maintenance more difficult but not impossible.
The batteries we are talking about weighed from 1800 lbs for a pallet jack to 5000 lbs for a large counter-balance electric forklift and averaged back in the 80's about a dollar a lb. new. If you could find an old style one today you would be competing with people who would be buying for scrap/salvage. I might look for an old one as well for use as battery backup for a whole house solar project since I could repair it myself and I can't afford the newer Tesla battery backups. The only recent experience I've had was to convert a selector machine like you would see at Lowe's or Home Depot to an elevator for a friends shop. We used the mast and electric hydraulic lift mechanism and removed the wheels and travel mechanism since we mounted it permenantly. By leaving the big 24 volt battery we were able to retain all the controls and just added limit switches to stop it on the second floor and a quality charging system which I salvaged from a 24 volt handicapped scooter. The battery was okay since it only ran the lft motor. If it has problems we will either repair it or replace it with 6 volt golfcart batteries in series to get our 24 volts. You might find a battery like this at an equip auction or scrap yard. The weight would make them desirable for scrap but not much else.
Thanks a bunch. I have a project staring me in the face, that I'm sure your comments will help me. Do you mind if I shoot you a couple of questions, if I need too? Thank you, Dennis
Honourable! Thanks a lot. I am very happy because I have recovered three old batteries according to the valuable informations provided by you. The result is highly very good. It is my very first attempt and I have succeeded. I have no knowledge of technology and I don't know about such things. I am grateful to you very much. Thanks a lot again.
You can also go cell to cell to ensure voltage is fairly even in each cell, dip both test leads into adjacent cells. ; ) Sorry for the late comment but this also helps to verify battery condition.
Kudos for the video content! Apologies for chiming in, I am interested in your thoughts. Have you researched - Lammywalness Trendy Trade Guide (search on google)? It is a great one of a kind guide for learning how to recondition batteries at home minus the normal expense. Ive heard some great things about it and my work buddy at very last got excellent results with it.
Hello need help asap So i was able to revive one of my 2 SLA battery (12v 150ah). The other has a problem because one of the 6 cells inside is reading 0.2v but the other 5 reads 2.1v. It wont continue charging because the other cells already reached max voltage. How do i fix this? also how to balance the 6 cells?
Wooow it work perfectly. I use 19v laptop charger to charge the 12v 7.2ah battery for one hour. Am still using the battery for my electric fence Energizer. Thanks so much
when the water over flows at the top of the battery when charging it, do I clean that water offwith a paper towel or something? Also when do i know when to reseal it?
Kudos for the video content! Excuse me for butting in, I would love your opinion. Have you considered - Lammywalness Trendy Trade Guide (should be on google have a look)? It is a smashing exclusive product for learning how to recondition batteries at home minus the headache. Ive heard some amazing things about it and my best friend Jordan at very last got amazing success with it.
interesting points ,if anyone else needs to find out about how to recondition old car batteries try Panlarko Recondition Planner (do a google search ) ? Ive heard some incredible things about it and my brother in law got great results with it.
I added water and battery acid, while it is recharging, the battery become hot and the liqued going out. This is one hour recharging. No advance in volt
After recovery of battery, should one through water from battery out?? If not, ithen what if. Attery is installed in a ups which keeps battery in lay flat horizontal position?
Rainwater! Meat syringe! Your coolness just doesn't stop. I've got to try this, I have two maybe three of these batteries hanging around seeming totally dead.
I\'m not sure but ,if anyone else wants to discover battery reconditioning business try t.co/YpdloYO92F ? Ive heard some pretty good things about it and my neighbor got great success with it.
The true test as to whether or not a battery is fully recovered is to perform a load test and capacity test. So what capacity (at the 20 hour rate that is shown on that battery) did you measure?
If I understand correctly, these batteries don't have liquid water or liquid acid even when new, and they are called gel cells. They can be used in almost any orientations in UPS applications. After adding the water, can you still use it sitting side ways?
The "gel" in a gel cell is silica sand. The electrolyte fills the spaces like a sponge. The normal level of the electrolyte is entirely contained in the sand. The battery should be fine in any position. If I were to copy this method, I'd add the water, charge the cells, drain off the excess water and then replace the caps.
you need to add "desulfate from the SOFT sulfation only" into your description..there are two types of sulfation...soft, which is reversible..and hard, which isn't reversible ..and the hard one is one which happens the most to charge-deprivated long-stored batteries and nothing in this world can fix it
By just adding rainwater you're not going to realize the battery's full potential. You should be using distilled water and add some battery acid before topping up. Otherwise you will be diluting the electrolytes. But I have learnt how to flick a razor blade across the work surface.. Nice watch
Hey dickhead battery acid does not evaporate water does when you are working with an undamaged battery that has dried up the littlebit of water in the cells is actually concentrated battery acid so adding water only dilutes it back to its original concentration. This video kicks ass
Hello and thanks for the video, I have a couple of questions. My UPS battery is not maintaining the charge, it is in use, last week we had a blackout and the UPS got off immediately. 1. For how much time should I have the battery out of the UPS, disconnected, before it is safe to open the battery?. 2. can I use only seawater to improve the performance and useful lifetime? Thanks in advance.
Great video. I never knew these batteries were of the lead acid variety and could be recovered. I figured they were some type of gel cell. (OBTW) I noticed the Casio calc watch you are wearing...I have that same identical one and speaking about batteries. I think I bought that watch in the mid 80's, so it's 25 to 30 years old. The band broke years ago and I tossed it in a drawer. The battery is the original (never been replaced) and it is still working after all these years sitting in a drawer. I take it out and check it from time to time to see if it's still going. It's only lost about 4 minutes in all this time. It amazes me every time!
The fact that the caps are sunk in tells me that no pressure is of concern as the water levels have dropped caving in the caps requiring water , sadly the fact the battery has sat for so long possibly damaged if not one all cells Internally leaving the battery useless , it might show charge and hold temporarily but inevitably will lose charge and render time repairing a wasted endeavor. Nice video and well spoken much appreciated and health wealth and happiness to u and yours sir.
@@jesscast5122 why would you direct someone to put their brain into a battery? I haven't seen any videos on this, does it really work? Did you put yours in one? D:
Yeah you want to fill to just cover the plates as charge and discharge will effect the levels and it can boil and bubble when you charge it if no room for gas and such is left to allow expansion you might cause the battery to rupture if it doesn't have any kind of overflow or pressure release valve, like all sla batterys do not have... the other problem with agm sla battery recovery is that capacity is probably going to be nothing like a new one as the crystallized acid will form between the plates and the glass matting and spread plates sometimes even cause some plates to fracture and recovering from this isn't possible without recasting the lead with the sulfation insulating parts of the left over plates held into place by the agm making pulsing and such not able to cause it to fall off. probably get some use from them in conditions where they are not moving anymore and always in the upright position. wouldn't use them for a scooter or anything...
If you don't have a pimp charger, but just a regular charger, how do you revive it if it shows 0V and does not accept charging current after filled up with water? Thank you.
Luxoriginalis You can use a Dewalt (or any other good quality) cordless drill charger. It not only pulse charges, it also tests the battery to make sure it can even be charged at all and it will shut down when the battery is full.
This is OK if your not going to put it under any usable load. In all reality these days its easier and safer to just buy some new batteries. I just bough 3 of these same 20Hr 12 volt batteries on ebay brand new for $20 shipped to my door. Now if these were higher cap more expensive types ($400 ea) then yes you want to try to salvage them and get more life from them. This ONLY works if the battery is not sulfated and the plates are not damaged. If the plates are damaged you can damage your charger, cause the battery to become too hot too fast and vent or even explode, or start a fire so do this stuff outside always! Instead of a razor blade use a small metal putty knife and a ball pin hammer and tap it gently in until the handle touches the battery then pry it up from the end. You can speed this up with a heat gun too. Putting the cap back on you can epoxy it back on.
Great Video. Did U need 2make a cut under the posts or are only 3 side cuts needed? Also, the rain water - what are its qualities vs Tap Water or Distilled? Thanks in advance 4the Great Video/info.
I'm enjoying my DP2! I'm restoring every old battery I can get my hands on. I have a problem with a new SLA I got off ebay: When inside the UPS, the battery is on its side and leaks some liquid. Any suggestions how to make sure those caps stay on snug (but not too snug)? It's a battery very similar to the one in this video. Thanks
why fill it so fully, you'd dilute the acid more than it's meant to be, and probably reduce the recoverable capacity. the electrodes in this type of SLA battery are more like sponges, they just need to be wet, not floating in liquid acid which could easily leak out if the battery gets knocked over. the plugs are not designed to liquid keep acid in, just let gases out flooded lead acid batteries, like in a car, have more robust screw down caps as they need to keep liquid acid in check.
Couldn't agree more with your conclusion. These batteries should NEVER be flooded like a car battery/Flooded Lead Acid. By just getting enough moisture into each cell that the "matting/Sponge" is damp and never totally wet, the battery "May" be recoverable if no internal warping or degradation has taken place 👍👍👍
Was looking at the site you have linked, why is "opensource" image posted on the page of the charger, but no actual source documents, i.e. no schematic, board design files, or bom?
Yeah, I know, right!!! Does it have to be a "Specific" type of rain water or can I just use the "Acid Rain Water" that we get here in "My" country or does the rain water in his area distil itself before leaving the clouds, leaving it particulate free??? 🤣🤣🤣
You'll need a charger like da pimp to overcome the internal resistance. Also you might want to check each cell and see the readings (not while charging).
thank you very much !!! most likely you saved me about $30.00 I have a monster portable speaker that I have not used for over two years and now the battery is dead. How interesting they way you measured each cell. Thanks again.
I mean, it is called a *Sealed* Lead Acid battery for a reason. They are not designed to be opened and filled with water. the electrolyte is absorbed into the plates during the manufacturing process. But you may get a little bit of life out of it for short term, but I wouldn't use it for emergencies.
Hi. After charged, should I drain part of the water or can I leave the battery with water? And can I charge a "old" battery with a standard charger, like the standard UPS Charge System?
Excellent methods, I didn't know before. I was finding new, but odd brand drill packs at truck line salvage stores and moving the rechargeable cells in those into these old battery cases, to make up 12 volt battery packs for my radios, but I definitely like this recovery even method..
@Michael Robinson Distilled water is pure water. Rainwater condenses around cloud condensation nucleii such as mineral dust, pollen, bacteria etc and then collects huge amounts of airborne dirt, vehicle pollution , minerals etc as it fall through the atmosphere. Rainwater is actually pretty dirty and is also usually collected from dusty gutters, metal buckets or any othe container left outside for weeks to collect muck.
What coincidence finding this video 3days after I did this to a CSB 7,2ah battery :) I got the battery for free and checked it had ok voltage, when trying to draw alot of amps it died immediately and charged suspiciously fast. Then I decided to check the caps and surprise surprise I could see all the lead plates dry inside so I filled er up and now it starts my mini quad easily.
Ive bought a £250+ electric scooter that's basically just lost power due to low battery fluids. Cheap fix but I read somewhere that you can (or "must) use distilled water. So rainwater is also ok? Good to know. I also read that you can add soda to the water to help set up the charging. Is that also correct or a good idea?
Aww man so awesome I'm in a wheelchair and I had a power wheelchair given to me and it has set about as long as your battery it takes two batteries and they are about $300 a pair I can't afford that so I'm going to let these cool off they have been on charge a while and I'm going to take them apart and try what you just showed me thank you so much my good friend
Roy Nelson I have a brand new electric wheel chair that was my mothers, the ticket on it was $10,000 and some change. The two batteries on it are $400 each but I was able to revive only one. I use it on my solar power battery bay now. As for the chair.. I need to find a buyer for it. I'm not selling it for $10K lol that's insane! but it has all the bells and whistles on it. I also have a 3 wheel Scooter that I modified the gearing on to go faster... Mom liked that one best, she was a big drag racing fan too so right up her ally! It has the seat that goes up and down with a button press and a charger built into it with a retractable cord.
That's awesome brother it really is I have a youtube channel you should check it out sometime I put some motorcycle speakers on my power wheelchair MC 400 they rock pretty good lol I'm into RC cars and stuff I do different kinds of videos with those me and my grandson when he's here I do a lot on my own I'm doing a build right now and test and tuning put some boost bottles when this one here better throttle response
Roy Nelson I been doing some Arduino wireless stuff recently, I got some of those esp wifi modules and I can see great potential with those for home automation and even RC applications. Somewhere around this mess of a shop I have an RC drone with a servo camera on it.. Paid over $450 for it a year ago.. I use it to inspect radio towers before we climb them.
That's awesome brother and hell yeah on the drone that's really cool what you used it for I've never had one one of these days I will get one after I quit playing with these cars and settle down for a little flight time I want to get an airplane and its called the e flite apprentice that's what I want man
I never had an actual RC plane, a friend of mine had a B-52 RC gasoline plane and it was HUGE! The drones are tricky to fly and takes practice because you don't want to crash one, expensive to repair.. I also have model HO scale trains too.
Chaz Madge as hydrogen gas is produced through the small vents, it will over time lose its content. If batteries were not vented, gas build up would lead to a rupture or explosion.
plastic isn't 100% waterproof, also the hydrogen and oxygen of the water (and other gases from electrolysing sulfuric acid? i don't know) can vent out if there isn't a part of the battery that burns it down to water again (so i heard), also as WireTamer said, build in obsolescence also could be a thing with those batterys

*Guys I found the best Battery Reconditioning program over here **Batteryrestorationn.blogspot.co.uk** all you guys should try it*
To restrict any spitting of fluids which may occur, simply position your lever, then put a rag over, so you’re sort of working blind.
This method can also work in engineering, if you’re removing fasteners that may be sprung or clipped in some manner, a little awkward at times, but easier than looking for that clip that has just been projected fifty feet across the workshop.
Eye protection too, don’t forget that.
You would not have pressure in there. These caps are one way valves that relieve any internal pressure during charging but otherwise create a seal. Also known as a 'Valve regulated sealed lead acid battery'.
A 12v battery with less than 1v at the terminals that's been sitting around for 4 years will be very difficult if not impossible to recover to a good enough internal resistance by just adding water. There will be thick level 3 sulfate bonds on the plates. Terminal voltage is one thing, let's see you draw some current out of this :)
I'm also not sure why you think you would blow a connection between two cells by attempting to charge without adding water?
M0UKD Couldn't the connection in theory be affected by the lack of acid/water ?
I'm still new to this kinds of stuff, so I'm slowly learning about it.
M0UKD
M0UKD
I know this is old, but I will say this. There was never "water" in the battery to begin with. The acid is absorbed when the battery is manufactured, like M0UKD was saying, they are Valve Regulated. They are sealed from the factory and do not require any acid/water to be put in. simply put, after 4-6 years, its best to just replace it.
That is only if the valves are working. This guy has clearly experienced a pressure incident, or he would not have mentioned it.
Please use distilled water to refurbish the batteries, makes it easier to recycle and they last longer.
You can use oil, water or label remover to get rid of the brown tape.
He used rainwater, which is probably good enough off the cuff.
@@jcpt928 why cant you use tap water? mineral content should help conductivity no?
@@chrishayes5755 No. The minerals in tap water can increase both sedimentation and stratification in the battery, and they dilute the electrolyte [in deep cycle batteries].
Tap water has a ton of added chemicals the city puts in That might turn the batteries gay

I have a 12 volt Lead Acid Battery . I have charged it a very long time with Schumacher changer with 1.5 amp It is still only 6 volt in the battery. Why?
Put some salt in one pinch
@@gamespace0125 are you for real
Half of your cells are dead.
So use rainwater, but if it’s not raining water purified, water is fine tapwater distilled water. I’ve always used distilled water in my car batteries. If you do not have distilled water available is bottled water acceptable or should you only use distilled water or rainwater?
I would highly recommend distilled water.
Use compressed air to clean the inside of the battery, as opening the caps of the cells would let the junk into the cells. Hold the caps down with your thumb so that the rush of the air will not unseat them. A old toothbrush could be used to brush any gunk away from the cell openings before you remove the caps. Clean each cell thoroughly.
Just distilled water added, and not new sulfuric acid needed? Nice to see these "paperweights" I've got laying around may still be useful.
Thanks Rick..The jumping about should be reduced greatly once the cells are refilled and the charger has a few hours. Since you might have been charging them dry be sure and do the cell check with a voltmeter and confirm all the cells are still giving roughly +2v up from the previous.
sir if I don't have a charge
how method can be?
Is there an updated link where we can get the plans for the charger? Link is not working now. Thanks!
Watched your video, managed to restore & use successfully an emergency power supply.
Thank you.
Does the pimp work for gel batteries?
Thanks so very much for taking the time to record, upload and share your knowledge with us. Respect from Ireland.
I know this video is 10+ years old but thanks for that valuable info in 2023! I'm looking to restore my Cyberpower UPS Backup batteries that are SLA.
BTW, what voltage are you recharging at, 60 volts DC? WoW!
Hey Mikey, do you have the schematic for dat pimp charger, and why does it charge at such high voltages, I wouldn't think that was good for the battery. very good thumbs up!!
Please I am trying to understand he used only rain water, which he poured into the battery containers, I have seen other videos with stated battery acid to be used.
Is this water method right ?
Also if I don't have a pimp charger, can I just place it back in the UPS to charge ?
wow. I haven't seen a Casio calculator watch since I was in 2nd grade. my friend freaked out when he realized he'd dropped it in the garbage one day and spent like half hour digging through old hot dogs and ketchup to get it back; a memorable moment.
There are a few things for battery reconditioning
never attempt to do this unless you know what you are doing - the acid can burn you
check the voltage first - there may be a dead cell which would waste your time.
Check the battery fluid.
Try to fully charge the battery.
(I learned about these and more on Jons mender guide website )
I should learn to read slower...I thought to myself "why would he have a garage full of old hotdogs and ketchup?"
Then I read again.....GARBAGE!!
It`s surprising how easy this reconditioning steps are t.co/Folp6e7Dkc ! My auto batteries, cellphone battery, drill battery, camera battery, along with other forms of batteries are all repaired and useful again! Since starting this program I have ended up saving over $ 400 on batteries!?
Battery water is perking out of cell tops. ?
The only thing that worried me was when he said he was going to sell it. It's not going to have a long life, it was obviously thrown away for a good reason. I've done this trick myself and the batteries quickly lost capacity. By the way, I was told that top plate is purposely easy to prise off because if the battery has to vent it'll blow those rubber seals and also blow that plate off rather than blow the battery apart. Overusing epoxy or gorilla glue may negate that safety feature. Not that I'd like to be around if it did blow.
If you will be using the device daily, even a worn battery can last a long time, despite it discharging rapidly. When I was 18, my car sat for a month with a six year old battery and it was completely dead, or so I thought, My neighbor did some sort of procedure like this, and brought it up to full charge. I would use that same battery all through the winter, driving my car for half an hour twice or more each day, to school or work and back home. When I let it sit for several weeks over the summer, it died again. Rather than go through the procedure again and risk getting stuck, I asked for, and got, a new battery for my birthday. But it showed me that even batteries on the verge of death can sometimes be kept alive with frequent recharging cycles.
I have love and respect for you in my heart. You are one of my teachers no doubt. When I saw so good result, there was your face in front of my eyes that I saw in your video. It is due to me to tell you honestly about my success that is because of you. Thanks.
Old 64 goat, I am 67 and I have recovered many batteries. but not all of them. I add distilled water from the grocery store at $0.75 per gallon and a gallon lasts me several years. (Rain water has some dissolved minerals from running down the roof and in the air it picks up CO2 and becomes mild carbolic acid so distilled water is the best! ) The sealed battery he is working on is a valve regulated not a gel cell and many are in use if the battery is not too dry the gel will absorb the water.
Hi? Good day. I would like to ask if should i throw the old water from my battery and put a distilled water with salt. Or i keep them as is and just add the distilled water and salt?
Thank you in advance, god bless
What happens if only 4 cells have bubbles coming out the hole? Does it means only 4 cells are working? Sorry I don’t have a voltmeter rn.
Dude you are awesome. And I love your calculator watch! I used to have one of those back in the 80s. Sweet.
What's the name of acid used?
Comments included this "Iron Out" product and dumping all fluids and replacing with distilled water. Why were you not using new battery acid instead of water? I have no experience with these small batteries but lots with big batt for electric warehouse equipment. We would remove those cells gently wash off the sulfation and clean out the case. As long as the plates were okay and the sulfation was no longer present we would refill with new battery acid, ck the specific gravity of the liquid and recharge like a new battery.
Ok bud, you have presented the same problem which you started your comment out with. How did you remove the sulfation? Iron out? How much did you use?
JM these are batteries that are in metal cases with individual cells that are sealed in with an asphalt product. These batteries weigh anywhere from 2 to 5,000 lbs. depending on the equipment and voltage, amperage requirement. We would remove the inner cell connectors and pull the non-performing cell completely out of the case. We then cleaned the cell with baking soda and water and plain water under no pressure greater than what you got from a hose. We vacuum out and cleaned the case with the same solution. After a thorough drying we reassembled the cell in the battery case. We also had floor drains in our battery room where all effluent went into a concrete vault. We had it pumped as necessary by an environmentally approved company. I hope I have answered your question. The battery companies are building these batteries (the individual cells in plastic now) which makes this type of maintenance more difficult but not impossible.
@@denniswarren3211 Sounds like a battery I would Like to "get my hands on"
Probably hellishly expensive I would assume!
The batteries we are talking about weighed from 1800 lbs for a pallet jack to 5000 lbs for a large counter-balance electric forklift and averaged back in the 80's about a dollar a lb. new. If you could find an old style one today you would be competing with people who would be buying for scrap/salvage. I might look for an old one as well for use as battery backup for a whole house solar project since I could repair it myself and I can't afford the newer Tesla battery backups. The only recent experience I've had was to convert a selector machine like you would see at Lowe's or Home Depot to an elevator for a friends shop. We used the mast and electric hydraulic lift mechanism and removed the wheels and travel mechanism since we mounted it permenantly. By leaving the big 24 volt battery we were able to retain all the controls and just added limit switches to stop it on the second floor and a quality charging system which I salvaged from a 24 volt handicapped scooter. The battery was okay since it only ran the lft motor. If it has problems we will either repair it or replace it with 6 volt golfcart batteries in series to get our 24 volts. You might find a battery like this at an equip auction or scrap yard. The weight would make them desirable for scrap but not much else.
After filling the battery cells how much voltage to charge and is it AC or Dc
Thanks a bunch. I have a project staring me in the face, that I'm sure your comments will help me. Do you mind if I shoot you a couple of questions, if I need too? Thank you, Dennis
Thank you for posting this. I've never repaired a sealed lead acid battery before, but your method looks good. :)
Honourable!
Thanks a lot. I am very happy because I have recovered three old batteries according to the valuable informations provided by you. The result is highly very good. It is my very first attempt and I have succeeded. I have no knowledge of technology and I don't know about such things.
I am grateful to you very much. Thanks a lot again.
No mention of the badass calculator watch!!! And it still works!!
You can still buy those, saw them at Wal Mart recently. Still Casio, just like the ones we had in the '80s.
Rain water, NOT distalled?
Rain water is distilled water
You can also go cell to cell to ensure voltage is fairly even in each cell, dip both test leads into adjacent cells. ; )
Sorry for the late comment but this also helps to verify battery condition.

Hello need help asap
So i was able to revive one of my 2 SLA battery (12v 150ah). The other has a problem because one of the 6 cells inside is reading 0.2v but the other 5 reads 2.1v. It wont continue charging because the other cells already reached max voltage.
How do i fix this?
also how to balance the 6 cells?
this was helpful got my scooter battery back to life thanks.
Wooow it work perfectly. I use 19v laptop charger to charge the 12v 7.2ah battery for one hour. Am still using the battery for my electric fence Energizer. Thanks so much
when the water over flows at the top of the battery when charging it, do I clean that water offwith a paper towel or something?
Also when do i know when to reseal it?

Please tell us about that battery charger.
interesting points ,if anyone else needs to find out about how to recondition old car batteries try Panlarko Recondition Planner (do a google search ) ? Ive heard some incredible things about it and my brother in law got great results with it.
I added water and battery acid, while it is recharging, the battery become hot and the liqued going out. This is one hour recharging. No advance in volt
After recovery of battery, should one through water from battery out?? If not, ithen what if. Attery is installed in a ups which keeps battery in lay flat horizontal position?
Rainwater! Meat syringe! Your coolness just doesn't stop. I've got to try this, I have two maybe three of these batteries hanging around seeming totally dead.
Very Good video. one question, replacing the cover. does that cover just press back on?
how long do I need to wait to open the cells if I have been trying to charge
I\'m not sure but ,if anyone else wants to discover battery reconditioning business try t.co/YpdloYO92F ? Ive heard some pretty good things about it and my neighbor got great success with it.
The true test as to whether or not a battery is fully recovered is to perform a load test and capacity test. So what capacity (at the 20 hour rate that is shown on that battery) did you measure?
If I understand correctly, these batteries don't have liquid water or liquid acid even when new, and they are called gel cells. They can be used in almost any orientations in UPS applications. After adding the water, can you still use it sitting side ways?
Sure, it doesn't effect the performance.
Won't it leak if sideways?
The "gel" in a gel cell is silica sand. The electrolyte fills the spaces like a sponge. The normal level of the electrolyte is entirely contained in the sand. The battery should be fine in any position. If I were to copy this method, I'd add the water, charge the cells, drain off the excess water and then replace the caps.
Those are not gel batteries...
This is an SLA battery , what you refer to is AGM.
Good to see the Doc back streaming
feel like this clip dated back to the 80's where the watch calculators was popular back then.. excellent project to recover the dead battery
WHAT BRAND IS CHARGER U USE? NICE VIDEO.
you need to add "desulfate from the SOFT sulfation only" into your description..there are two types of sulfation...soft, which is reversible..and hard, which isn't reversible ..and the hard one is one which happens the most to charge-deprivated long-stored batteries and nothing in this world can fix it
Uu

@@JohnSmith-bd3xh No thanks, not even clicking that link.
By just adding rainwater you're not going to realize the battery's full potential. You should be using distilled water and add some battery acid before topping up. Otherwise you will be diluting the electrolytes. But I have learnt how to flick a razor blade across the work surface.. Nice watch
H 2. So4. Added
Hey dickhead battery acid does not evaporate water does when you are working with an undamaged battery that has dried up the littlebit of water in the cells is actually concentrated battery acid so adding water only dilutes it back to its original concentration. This video kicks ass
No need to add "battery acid". When the water evaporates the sulfuric acid stays behind. Just use distilled water.

Hello and thanks for the video, I have a couple of questions. My UPS battery is not maintaining the charge, it is in use, last week we had a blackout and the UPS got off immediately. 1. For how much time should I have the battery out of the UPS, disconnected, before it is safe to open the battery?. 2. can I use only seawater to improve the performance and useful lifetime? Thanks in advance.
Great video. I never knew these batteries were of the lead acid variety and could be recovered. I figured they were some type of gel cell.
(OBTW) I noticed the Casio calc watch you are wearing...I have that same identical one and speaking about batteries.
I think I bought that watch in the mid 80's, so it's 25 to 30 years old. The band broke years ago and I tossed it in a drawer. The battery is the original (never been replaced) and it is still working after all these years sitting in a drawer. I take it out and check it from time to time to see if it's still going.
It's only lost about 4 minutes in all this time. It amazes me every time!

Why rain water ? Can it be just regular water ? Or distilled water ?
Coz rain water is almost like distilled water ...
U can use distilled water too
The fact that the caps are sunk in tells me that no pressure is of concern as the water levels have dropped caving in the caps requiring water , sadly the fact the battery has sat for so long possibly damaged if not one all cells Internally leaving the battery useless , it might show charge and hold temporarily but inevitably will lose charge and render time repairing a wasted endeavor. Nice video and well spoken much appreciated and health wealth and happiness to u and yours sir.
Can battery like that with 1 dead cell still be used as 9 volt battery for 9 volt fan ? I
Is there a particular reason you used rain water or could I used bottled or distilled?
How to NEVER pay for new Batteries Ever Again: JoxCharge. com
distilled water,, always
Ya
voltage do not indicate battery recovery and 2:45 these rubber caps cannot physically build up significant pressure.
so it's all about filling the cabs with distilled water ?
+gfg5452
yes
what was the green-cased gadget - something home made?
I always believed that when topping up a battery you only went just over the plates. Not until it flowed out of the top of the cells.?
Yes, you don't want to add to much because of the ratio of acid.. It should only be done as a last ditch effort anyway.
USE your own brain.........if you have one.................................
@@jesscast5122 why would you direct someone to put their brain into a battery? I haven't seen any videos on this, does it really work? Did you put yours in one? D:
Yeah you want to fill to just cover the plates as charge and discharge will effect the levels and it can boil and bubble when you charge it if no room for gas and such is left to allow expansion you might cause the battery to rupture if it doesn't have any kind of overflow or pressure release valve, like all sla batterys do not have... the other problem with agm sla battery recovery is that capacity is probably going to be nothing like a new one as the crystallized acid will form between the plates and the glass matting and spread plates sometimes even cause some plates to fracture and recovering from this isn't possible without recasting the lead with the sulfation insulating parts of the left over plates held into place by the agm making pulsing and such not able to cause it to fall off. probably get some use from them in conditions where they are not moving anymore and always in the upright position. wouldn't use them for a scooter or anything...
Did you take the water out after fully charged and the put the caps back on?
If you don't have a pimp charger, but just a regular charger, how do you revive it if it shows 0V and does not accept charging current after filled up with water? Thank you.
Luxoriginalis I was wondering the same. but i have a UPS system. i am going to try charging my battery with that.
Luxoriginalis This entire video is an advertisement for da-pimp charger
Nasrani MinAlGharb Pimp my charger ;P
Luxoriginalis You can use a Dewalt (or any other good quality) cordless drill charger. It not only pulse charges, it also tests the battery to make sure it can even be charged at all and it will shut down when the battery is full.
This is OK if your not going to put it under any usable load. In all reality these days its easier and safer to just buy some new batteries. I just bough 3 of these same 20Hr 12 volt batteries on ebay brand new for $20 shipped to my door.
Now if these were higher cap more expensive types ($400 ea) then yes you want to try to salvage them and get more life from them.
This ONLY works if the battery is not sulfated and the plates are not damaged. If the plates are damaged you can damage your charger, cause the battery to become too hot too fast and vent or even explode, or start a fire so do this stuff outside always!
Instead of a razor blade use a small metal putty knife and a ball pin hammer and tap it gently in until the handle touches the battery then pry it up from the end. You can speed this up with a heat gun too.
Putting the cap back on you can epoxy it back on.
What do you money trolls doing on a DIY page!
Keep your money.
This is about learning survival skills, not penny pinching
may i ask, what reason for this "recovery"...?
do you doing it professionally ?
Because it's like a dollar a gallon for distilled water, compared to 25-60 dollars for a new battery, depending on brands.
Great Video. Did U need 2make a cut under the posts or are only 3 side cuts needed? Also, the rain water - what are its qualities vs Tap Water or Distilled? Thanks in advance 4the Great Video/info.
I'm enjoying my DP2! I'm restoring every old battery I can get my hands on. I have a problem with a new SLA I got off ebay: When inside the UPS, the battery is on its side and leaks some liquid. Any suggestions how to make sure those caps stay on snug (but not too snug)? It's a battery very similar to the one in this video. Thanks
Why my acid battery 12v after i filled distilled water getting heat
why fill it so fully, you'd dilute the acid more than it's meant to be, and probably reduce the recoverable capacity.
the electrodes in this type of SLA battery are more like sponges, they just need to be wet, not floating in liquid acid which could easily leak out if the battery gets knocked over. the plugs are not designed to liquid keep acid in, just let gases out
flooded lead acid batteries, like in a car, have more robust screw down caps as they need to keep liquid acid in check.
Couldn't agree more with your conclusion. These batteries should NEVER be flooded like a car battery/Flooded Lead Acid. By just getting enough moisture into each cell that the "matting/Sponge" is damp and never totally wet, the battery "May" be recoverable if no internal warping or degradation has taken place 👍👍👍
No acid is added? I do the same with acid and it workes fine
DUDE... that cell testing thats bloody cool
bkingk8
Was looking at the site you have linked, why is "opensource" image posted on the page of the charger, but no actual source documents, i.e. no schematic, board design files, or bom?
Is the LCD flickering or is that the camera effect?
Camera effect.
oh,ok thanks :)
Rainwater to refill???
Yeah, I know, right!!!
Does it have to be a "Specific" type of rain water or can I just use the "Acid Rain Water" that we get here in "My" country or does the rain water in his area distil itself before leaving the clouds, leaving it particulate free???
🤣🤣🤣
You'll need a charger like da pimp to overcome the internal resistance. Also you might want to check each cell and see the readings (not while charging).
thank you very much !!! most likely you saved me about $30.00 I have a monster portable speaker that I have not used for over two years and now the battery is dead. How interesting they way you measured each cell. Thanks again.
Really needed to see the proof once you were finished
Please tell me you filed it with plain water that we use for drink or ???
I mean, it is called a *Sealed* Lead Acid battery for a reason. They are not designed to be opened and filled with water. the electrolyte is absorbed into the plates during the manufacturing process. But you may get a little bit of life out of it for short term, but I wouldn't use it for emergencies.
Hi. After charged, should I drain part of the water or can I leave the battery with water? And can I charge a "old" battery with a standard charger, like the standard UPS Charge System?
+Thiago Rocha (thiagoqualquercoisa) Leave the water in there it turns to acid, take it out and you fuck up your battery again!
+Thiago Rocha (thiagoqualquercoisa) so you poured water in didn't you ?
Excellent methods, I didn't know before. I was finding new, but odd brand drill packs at truck line salvage stores and moving the rechargeable cells in those into these old battery cases, to make up 12 volt battery packs for my radios, but I definitely like this recovery even method..
can i use distilled water instead of rain water?
Yes, you should use distilled water. Rainwater is only used when you don't have distiled water.
Really, just use rainwater? With all its ionization and contamination with minerals? I'd have thought you'd have to use distilled water...
@Michael Robinson Distilled water is pure water. Rainwater condenses around cloud condensation nucleii such as mineral dust, pollen, bacteria etc and then collects huge amounts of airborne dirt, vehicle pollution , minerals etc as it fall through the atmosphere. Rainwater is actually pretty dirty and is also usually collected from dusty gutters, metal buckets or any othe container left outside for weeks to collect muck.
You used rain water?
What coincidence finding this video 3days after I did this to a CSB 7,2ah battery :)
I got the battery for free and checked it had ok voltage, when trying to draw alot of amps it died immediately and charged suspiciously fast. Then I decided to check the caps and surprise surprise I could see all the lead plates dry inside so I filled er up and now it starts my mini quad easily.
you filled them up with what? drinking water? pure water? battery acid? plz let me know dear
Distilled water since water evaporates leaving mostly the acid behind :)

Ive bought a £250+ electric scooter that's basically just lost power due to low battery fluids. Cheap fix but I read somewhere that you can (or "must) use distilled water. So rainwater is also ok? Good to know. I also read that you can add soda to the water to help set up the charging. Is that also correct or a good idea?
Aww man so awesome I'm in a wheelchair and I had a power wheelchair given to me and it has set about as long as your battery it takes two batteries and they are about $300 a pair I can't afford that so I'm going to let these cool off they have been on charge a while and I'm going to take them apart and try what you just showed me thank you so much my good friend
Roy Nelson I have a brand new electric wheel chair that was my mothers, the ticket on it was $10,000 and some change. The two batteries on it are $400 each but I was able to revive only one. I use it on my solar power battery bay now. As for the chair.. I need to find a buyer for it. I'm not selling it for $10K lol that's insane! but it has all the bells and whistles on it. I also have a 3 wheel Scooter that I modified the gearing on to go faster... Mom liked that one best, she was a big drag racing fan too so right up her ally!
It has the seat that goes up and down with a button press and a charger built into it with a retractable cord.
That's awesome brother it really is I have a youtube channel you should check it out sometime I put some motorcycle speakers on my power wheelchair MC 400 they rock pretty good lol I'm into RC cars and stuff I do different kinds of videos with those me and my grandson when he's here I do a lot on my own I'm doing a build right now and test and tuning put some boost bottles when this one here better throttle response
Roy Nelson I been doing some Arduino wireless stuff recently, I got some of those esp wifi modules and I can see great potential with those for home automation and even RC applications. Somewhere around this mess of a shop I have an RC drone with a servo camera on it.. Paid over $450 for it a year ago.. I use it to inspect radio towers before we climb them.
That's awesome brother and hell yeah on the drone that's really cool what you used it for I've never had one one of these days I will get one after I quit playing with these cars and settle down for a little flight time I want to get an airplane and its called the e flite apprentice that's what I want man
I never had an actual RC plane, a friend of mine had a B-52 RC gasoline plane and it was HUGE!
The drones are tricky to fly and takes practice because you don't want to crash one, expensive to repair..
I also have model HO scale trains too.
What kind of water you refilling is this?
So you have a sealed battery, yet it lost water? not very good seal then
Water? Its sulfiric acid
not pure, its diluted and its water that will evaporate first, that is why you top up with distilled water...
Ever heard of built in obsolescence?
Chaz Madge as hydrogen gas is produced through the small vents, it will over time lose its content. If batteries were not vented, gas build up would lead to a rupture or explosion.
plastic isn't 100% waterproof, also the hydrogen and oxygen of the water (and other gases from electrolysing sulfuric acid? i don't know) can vent out if there isn't a part of the battery that burns it down to water again (so i heard), also as WireTamer said, build in obsolescence also could be a thing with those batterys
Is this distilled water.?you put inside the battery..
Is this an agm battery?
NoVaKane Yes. VRLA/SLA.
