[@simonlinser8286]

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.

[@MrTeff999]

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....)

[@johnhamer4556]

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.

[@jspence001]

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.

[@ferrellsl]

[@sklarmgoodlifelab]

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.

[@نسيمالجنوب-و7ظ]

sir if I don't have a charge how method can be?

[@lomgshorts3]

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.

[@krazytroutcatcher]

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.

[@numbr6]

Just distilled water added, and not new sulfuric acid needed? Nice to see these "paperweights" I've got laying around may still be useful.

[@johnp21]

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?

[@etunimi4206]

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.

[@nickbillzoes86]

[@horstgaller4095]

M0UKD

[@ryanlabonte5341]

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.

[@wiretamer5710]

That is only if the valves are working. This guy has clearly experienced a pressure incident, or he would not have mentioned it.

[@bobgreene2892]

The sealed, lead-acid battery is designed to be used in almost any orientation, including mounted on its side. What prevents the distilled water you have added from leaking out of each cell, past the rubber seal/cap, and onto the appliance?

[@BobyUdrea]

[@DennisMilesEVprofessor]

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.

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.

[@propfella]

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.

[@d.e.b.b5788]

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.

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 )

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?

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.

[@denniswarren3211]

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-yx1lm]

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?

[@denniswarren3211]

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.

[@-Gadget-]

@@denniswarren3211 Sounds like a battery I would Like to "get my hands on" Probably hellishly expensive I would assume!

[@denniswarren3211]

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.

[@grahamkallis1127]

[@sklarmgoodlifelab]

An old style charger will not be able to overcome the resistane of batteries that have been left uncharged for years. You will need a charger that can handle a large voltage range even for brief periods to overcome the internal resistance.

[@brettmaxfield2974]

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.

[@-Gadget-]

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 👍👍👍

[@tigerbody1]

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.

[@moheideenalmadani3773]

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

[@goldbunny1973]

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?

[@SpiritsOfWarding]

Is there a particular reason you used rain water or could I used bottled or distilled?

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.

[@gang208]

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?

[@JahanZeb1976]

Sure, it doesn't effect the performance.

[@carlfalk7251]

Won't it leak if sideways?

[@videolabguy]

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.

[@j5892000]

Those are not gel batteries...

[@bn880]

This is an SLA battery , what you refer to is AGM.

[@RyanHull76]

Is there an updated link where we can get the plans for the charger? Link is not working now. Thanks!

[@whereserik]

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

[@EpicHeroSandwich]

battery tender is a maintenance charger used for 12v batteries on lawnmowers and motorcycles, it WILL NOT desulfate a battery. it's just a trickle charger. you need a specific tool to desulfate a battery.

[@roynelson7613]

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

[@Elfnetdesigns]

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.

[@roynelson7613]

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

[@Elfnetdesigns]

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.

[@roynelson7613]

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

[@Elfnetdesigns]

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.

[@bujjammapolimati4176]

Very helpful... But I have a doubt... That is What is the liquid used to fill that one.???? Help me..

[@gfg5452]

so it's all about filling the cabs with distilled water ?

[@FloryJohann]

+gfg5452 yes

[@adrianTNT]

I wonder if it would be relevant to accurately weight the battery when new, write it down, then over tiem check by weight how much it dried out, would that be relevant ?

[@imgrateful2750]

Good video. Thanks. Can you give us a brand name for your battery charger and where we might buy it.

[@sklarmgoodlifelab]

It is called the DP2 available from: screwdecaf.cx/dp2.html

i just need to know how long you should let a battery sit after charging before you open it

[@simpleme1279]

may i ask, what reason for this "recovery"...? do you doing it professionally ?

[@Whiskey5_]

Because it's like a dollar a gallon for distilled water, compared to 25-60 dollars for a new battery, depending on brands.

[@DiscoveringSpain]

I started the process but discovered classification inside the battery, should I fill it with coke or maybe baking soda to clean it?

[@nightingaleron]

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.?

[@mrtonytj5000]

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.

[@jesscast5122]

USE your own brain.........if you have one.................................

[@SailingSarah]

@@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:

[@NeverSuspects]

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...

[@liaomei843]

i saw in another video doing similar thing but added a spoon full of salt to the water to get battery to life again. What do you think of this idea?

[@ryanlabonte5341]

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.

[@Elfnetdesigns]

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.
