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
@@LygerTheCLawyou did k no ow at a point in time. If you was used just the dial pad to write a text message. For letters like are would required a lot of key presses.

My technique is super simple. I open it up to get to the cells. Then make a boiling hot solution of potassium aluminum sulfate AKA alum. Then while still piping hot inject 1 or 2CCs per cell. Next I add distilled water to top them up over the plates. Then wait 24 hours. Next apply AC through a 100W light bulb to the battery till the bulb lights brightly. Next add a diode and give the battery DC for 15 minutes and charge normally. If it goes to high voltage very quick or fails to light the bulb the battery is dead. Helps to put the battery in a glass pie dish when doing the initial sulfation breaking and charge with the lightbulb. You can scale up to do bigger batteries the same way
if there is zero sulphuric acid and only distilled water you will get nada Volts..not even 1.. Se3cond point. Acid will take a while time to cause damage to yourself (skin), but it does stuff you. I've worked with hydrochloric acid for over 40 years on a daily basis without using any safety gear. I can no longer live in a cold climate as my skin absorbed the vapours and now my finger tips go black in the cold and hurt. My lungs are also fkd (never wore a mask) and the fumes burnt my insides. I'm old school thought it was tough not to wear ppe or safety gear and now I'm suffering, yes it took a long time, but you only need to get caught in a vapour cloud once and damage is done.. Sorry about the long winded comment but im just trying to explain how important it is to wear safety gear. BE CAREFUL HANDELING ACID
Do you want to restore a lead acid battery for sure ? You must remove the old electrolyte , clean out all the old mineral deposits , some of which conduct electrons from between the plates , the. Reassemble the battery , and put back new electrolyte .
So i have a similar battery , from a ups , 12v 7.2AH/20HR . So the story goes , i had an old ups i wanted to use, i left it to charge for 8hours roughly, The ups didnt get charged at all and it also heated , ALot . I took it apart to find the battery really hot and not holding charg at all . even after 8 hours of charging it had only 1.6 V . So i watched this video followed everystep. I used distill water i got from the hardware store . i put water in the battery waited about an hour before charging , while charging , i connected it back to the ups board because i dont have a battery charge. and like he said while charging i didnt put the caps vback on yet because of the gas build . so i connected it to the ups and it started charging , and very soon the water started bubling , very hot and started to overflow and flow out of the batter hole and this is being done in a well ventilated area but i ca definetly smell some sort of chemical in the air, a tiny hint
Can this method be used for battery that has been undergone say 800 cycles and can no longer hold charge well? Really appreciate your help on this. Thanks
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.
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
@@samuelumoh7744pls don’t use anything besides distilled water. The water is an insulator or dielectric. So the impurities in the water is what conducts electricity. So most non distilled water including rain water has minerals within it. Actually each rain drop is made from one meteor dust particles. It will allow the water molecules to condense on a surface. So the dust particles is the catalyst to water drop formation. So distilled water is the only thing to be used. A normal lead acid battery. As it is discharge power. The sulfuric acid turn into Epson salt. Also hydrogen gas is released in the process. Which highly flammable. They sell 12v dc battery for cars that has the holes that allow you to periodically add water. Due to evaporation over time.
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 ???
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)
@@allenrusselljr 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 )
@@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 .
My Welder disagrees, that bugger connected welding terminals on my battery and it started to boil, he did it 3 times, to cut the long story short, i'm still using a that battery on my hyundai.
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.
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.
Just reverse the polarity? fill with distilled water,drain the battery down to absolute zero (very important) volts and with a suitable charger capable of starting charge cycle at o.o volts place positive on negative and the negative on the positive and charge like you normally would.
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
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.
@@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

How high voltage did you get it to?
that was great thanks
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?
Capacity is much reduced and it won't last long at all.
You can restore a 'dead' battery with this method, but the problem is it will drain quickly. Basically no use.

I notice the gloves you don't have on!

one is a "schumacher speed charge" : amzn.to/3ViXuGO
and the other one is a cheap charger this one here : amzn.to/3XpkHtM
