This will work for a small amount of time cuz inside battery the cells r oxidated if u really do a good job u need to desulfate the battery with high current like welding machine and switch a few times the liquid inside till the oxidation on plates r gone

@MrJerrybnapao Місяць тому

Do you advise to use this revived battery together ( in series or parallel) with newer batteries?

@SFitzy-ms3vs Місяць тому

Does this reduce the capacity of the battery? If I used a battery acid solution instead of water, would it retain it's original capacity?

@lorddiablo8575 29 днів тому

I've tried the same method to my jump starter battery which has been dead for about one year. I used battery liquid bought from Auto Zone instead of distilled water or rain water. I also used the harbor freight charger like yours, but even leave it charged for 3+ hours, the voltage only stayed about 7 volts. Afterward, I also charged it over night but there is no gain of voltage .... So, I wonder if this method really works ???

@allenrussell6135 23 дні тому

Did you drain it first? If your using acid from AutoZone id drain it, fill with hot water and drain (even do this twice) then refill with straight acid. Wear eye protection and remember even 1 drop eats holes in your clothes (imagine it on your skin)

@@allenrussell6135 Thanks for reply ! The battery was totally dried out and there was nothing to drain ( just some black powder fell off when I turned it up side down ). I had filled with very hot water and drained it twice then filled it up with AutoZone battery liquid ( contains surphuric acid ), left the chambers open and charged for 2-3 hours, the voltage was just 7.0 then I charged it again for 24 hours but the voltage was just 7.4. ( I met a friend who is working in a battery shop and he told me, battery factory stopped using liquid and use GEL for more than 10 years and he told me that my battery could used GEL instead of battery liquid and told me to buy a new one )

@allenrussell6135 22 дні тому

@@lorddiablo8575 interesting, I didn't realize we could use a gel instead. I'll be honest, I'm clueless when it comes to gel batteries. What type of charger are you using? Does it have a boost option? The reason I ask is Ive seen videos where you remove the caps to each chamber and charge it again on the boost setting. I THINK but am not positive that they used 50 amps setting. You ONLY do this for 5 MINUTES every hour until every cell is bubbling. I haven't tried this process yet but people swear by it. Then there's always the chance your battery has an internal short in it. If that's the case then nothing's going to fix it .

What do I do if it is heating up? 12v 4ah. I'm running another 12v POS to POS and neg to neg.

@OMNITEK 2 місяці тому

a bit of heat is normal, you should see some bubbling, but if it gets too hot disconnect it...let it rest...then reconnect...but some heat happens in this process..just keep an eye out for the water not to boil over and make a mess plus make sure there is enough ventilation around and not in a closed room.

It wont stay charged. Ive never had one fully recover.

Can we use rain water.. and I have a gel battery are they the same?

@julian17359 2 місяці тому

No you can’t

@OMNITEK 2 місяці тому

i haven't tried myself with rain water but I have heard others use it in older batteries...i can't really say if it works but that is a cool idea for me to try though

@samuelumoh7744 27 днів тому

Can rain water be used in place of distilled water?

@petruse8893 Місяць тому

A snake oil promoting clip. If Pb battery is old and half dead/dead the plates will be irreversibly sulfated and no charging in the world is going to bring it back to life.All magic procedures using MgSO4 are BS and replenishing missing volume of electrolyte does nothing.Yes, you might reach 12V or slightly below.However it is about VOLTAGE and CAPACITY and a "recovered" battery will die within minutes.All warnings about H2SO4 at 33-34% are greatly exaggerated .One can stop one's finger into battery acid for a couple of seconds ,rinse it and observe no damage

@judsonmontemagno Місяць тому

To use the term "snake oil" would imply something is being offered for sale. Something that doesn't work or is not needed. Yet no sales pitch interview video. Also I have personally done this to my batteries and they work like new now. Keep your know it all opinions to yourself.

@petruse8893 Місяць тому

@@judsonmontemagno One can sell an item or an idea,a figure of speech.I'd like to believe you that all your " revived" batteries are almost " like new", but sorry,unless you demonstrate the capacity of the battery is at least 60% of its rating,it will remain a wishful statement.Recovery of the voltage rating is not good enough.If the battery is truly reconditioned,it will hold voltage levels relatively steady over weeks,once fully charged

this kind of batteries doesn't require acid or water like you did

@radiumreplays6045 19 днів тому

They only claim to be maintenance free. ALL lead acid batteries require the acid and water. Adding water back to replace the evaporated liquid is only the start. Lead oxides on the plates needs to be cleaned by applying high current in short bursts in order to de-sulfate.

@@makaveli087 Actually, I don't have sulfuric acid in my toilet -- so I don't have to worry about the occasional splash. This way I don't even need a protective cover for my toilet. I also just replaced my lead acid battery with a lithium ion battery, and I shouldn't ever have to replace it. For goodness sake, why play around with sulfuric acid when a splash could blind you, or burn you severely, when you can pony up $20.00 and buy a replacement?

@russchadwell 22 дні тому

Almost worked. Went from 3 volts to 11 volts. The Simonini starter needs 12 or slightly more volts. Starter sort of moved, but no full starter engagement. One cell is totally dead. A short down in the bottom somewhere, apparently. Saw a video on cutting apart the battery to rebuild the cell, but that seems to require welders, plastic reforming, fresh battery acid, new plate separators, stuff like that since you'd basically be rebuilding part of the battery after completely draining and cleaning it. Looks like, if there is nothing else I could do instead of all that, I'd be better off just buying a new battery. I am such a "consumer"... not a genuine technician at all, apparently! Lol.
