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.
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).
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
Water in Acid ? I heard that they are opposite of each other. then why battery manufacturer not making Affordable Sealed Rain Water Batteries ? my 7.5mah ups battery is not fully dead but giving poor performance over the years . should I add Rain Water in it. will give better performance ?
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?
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

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.
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.
Complete bullshit. I watched 10 of these similar videos, and nobody shows you a proper load test. The trick is that this way they can recover the Voltage somewhat, but not capacity. They show you a Voltage test, maybe a very ligth load for a coupe seconds, but never a proper load (60-70watts at least).
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].
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.
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.
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
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....)
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.
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.
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 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
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 ?
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
If you have a smart charger it wont start charge below 11 volt. Use a second full battery to get the old battery to 10.8 - 11 volt before connecting it to your smart battery charger. Or hook it up to your car battery and let it run for 15 minutes... Plus on plus - minus on minus...
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! 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 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
should be deionized water, not rain water, tap water or distilled water.... Deionized water is created though reverse osmosis which is far more pure than distilled water, deionized water is water that has had all the dissolved mineral particles removed from it in a way that is far more pure than distilled water.
@@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...
Depends how far gone it is,have done it many times and it works --to be really precise one should equalise the electrolyte by leveling each cell with one another water,check specific gravity,adjust with acid if necessary,and obviously level up with distilled water, charge up and off you go.
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!!
amazing, didn't know one could put water in those dry batteries. Well, now what is that charger? looks to start putting 50V in a 12V battery first, then 25, looks unusual procedure... usually chargers put a little bit over 13V to charge.
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.

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?
@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.
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.
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.
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.
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.
fingers are overrated .... i would get a 3rd world immigrant and exploit them.... hey buddy , ziz, zur , etc. ..... i have some razor blade work i want done
Well there's a reason there's do acid floating around in there You just diluted it less than half the strength it should be! Batteries deteriorate & after 5 years of even light use that battery would be toast. Utter waste of time. If you could do this to revive batteries I wouldn't have 5 pallets of car batteries here ready for the scrap man. I'd revive them & sell them for about $50 each on Facebook!
If There were No Available Parts Store Around, If You were on an Abandoned Island and Just Needed Something to Do for The Day, This Is Useful Information. One could go buy a Battery, Install it, Start Their Equipment and Have It Running in the Time it takes to do or watch this.
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 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!
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.

I recently got the EZ Battery Reconditioning program and just reconditioned two car batteries. The guides were very easy to follow [Check Details Here==> t.co/YpdloYO92F ]. I wish I would have found this years ago! 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 👍👍👍
I have revive many of these batteries. Distilled water will not do the trick. I simply use normal battery acid and fill the battery just covering the plates. you should be very careful not to spill acid and use gloves. In short many batteries will be as new but few of it will not
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..

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.
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.
this was helpful got my scooter battery back to life thanks.
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 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
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 ?
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.
@@lloyddubose4814 how do you mean?
@@jollynery😊dxxfxze
If you have a smart charger it wont start charge below 11 volt.
Use a second full battery to get the old battery to 10.8 - 11 volt before connecting it to your smart battery charger.
Or hook it up to your car battery and let it run for 15 minutes... Plus on plus - minus on minus...
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
Somebody just gave me a jump Box with one of these batteries inside. It's dead but I may try to revive it but a new one's only $20
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 .
Which liq you used to refill it
@@thief101 water
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
Dude you are awesome. And I love your calculator watch! I used to have one of those back in the 80s. Sweet.
should be deionized water, not rain water, tap water or distilled water.... Deionized water is created though reverse osmosis which is far more pure than distilled water, deionized water is water that has had all the dissolved mineral particles removed from it in a way that is far more pure than distilled water.
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...
voltage do not indicate battery recovery and 2:45 these rubber caps cannot physically build up significant pressure.
Bull, only a new battery will work. Needs taking off the internet this man.
Amen, this will never have anywhere near a usable capacity - voltage is not Amp-Hours!
Depends how far gone it is,have done it many times and it works --to be really precise one should equalise the electrolyte by leveling each cell with one another water,check specific gravity,adjust with acid if necessary,and obviously level up with distilled water, charge up and off you go.
What's the name of acid used?
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!!
amazing, didn't know one could put water in those dry batteries. Well, now what is that charger? looks to start putting 50V in a 12V battery first, then 25, looks unusual procedure... usually chargers put a little bit over 13V to charge.
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.
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?
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.
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.
I followed your video and managed to revive my battery which was almost dead. Thanks so much!
Just google VLRA battery you will see this is all crap!!!
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
Why my acid battery 12v after i filled distilled water getting heat
@2:03 just gently... flick the razor blade across the table xD

Don't fill to the top
hah i used to have that watch loved it. Had everything including a calculator.
This method does not work tried it on multiple batteries with no luck.
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?
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!

Watched your video, managed to restore & use successfully an emergency power supply.
Thank you.
Well there's a reason there's do acid floating around in there You just diluted it less than half the strength it should be! Batteries deteriorate & after 5 years of even light use that battery would be toast. Utter waste of time. If you could do this to revive batteries I wouldn't have 5 pallets of car batteries here ready for the scrap man. I'd revive them & sell them for about $50 each on Facebook!
If There were No Available Parts Store Around, If You were on an Abandoned Island and Just Needed Something to Do for The Day, This Is Useful Information. One could go buy a Battery, Install it, Start Their Equipment and Have It Running in the Time it takes to do or watch this.
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 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!
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.

Rain water, NOT distalled?
Rain water is distilled water
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.
Battery water is perking out of cell tops. ?
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 👍👍👍
I have revive many of these batteries. Distilled water will not do the trick. I simply use normal battery acid and fill the battery just covering the plates. you should be very careful not to spill acid and use gloves. In short many batteries will be as new but few of it will not
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..
Does the pimp work for gel batteries?
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.
It's a distilled water,, water for battery.
I think you put too much water.
Yes, he dissolved the acid way too much. That battery (if it does actually come back) won't last long!
I just replaced a 12volt lead acid with a new one and the new one wont hold a charge.Its in my crate guitar battery amp.I barely got thru a 45 minute set when the amp light showed red and started to distort.Hmm what could be the problem?thx
