Can you revive a dead car battery by inverting its polarity?

29999999999 KM

I did see a video of a guy reviving an old dead battery by passing 80 amps though it using an arc welder in a series of thirty-second bursts.
Presumably the lead sulphate deposit build-up was totally cleaned off.
Then he fully charged the battery normally and it performed like new.

I don’t give a shit about the battery, I’m impressed with that starter! I’m betting it’s smoked now 😂😂😂😂?

Too hell with the battery, I want the starter that can handle cracking that long! WOW

This is working 😂.
I think it was clik bait video.
Then i try on my cheap emergency lamp. No need to buy another emergency lamp 🎉🎉🎉

As a person who is stuck in a rural town where D8 batteries are almost 1000 dollars. My stockpile of bad batteries might see a new life😂

Kinda wonder if this would work on an optima red top AMG battery.

Landfill batteries? REPORTED

Because every starship engineer knows that reversing the polarity fixes everything!

I love your videos and the expirements are excellent to watch. Nazdravlje iz Australia ❤

I'm more impressed with the durability of that Lada starter motor!!!

Air bubbles are fine but Hydrogen bubbles are Dangerous.

Sometimes the reversing polarity technique is better than force charging. Force charging needs a higher voltage and current to boil the electrolytes. But in the reverse technique, even at a very low voltage and current, the liquid quickly boils.

Starting from the lead sulfate of a dead battery, either polarity is possible because there is nothing particularly fancy about either terminal except which plate becomes dominated by elemental lead (-) and which one is dominated by lead oxide (+). Probably will need to add more water to the battery after charging because the process consumes water. It's probably unsafe (fire or explosive case failure) due to different assumptions around the two phase flow venting of hydrogen.

The lead batteries plates have leadgrids filled with oxides. The sulphur acid will change these metallic grids by use to oxides, this twindle is irreversible ☠️

The polarity of a leadbattery is defined by the chemistry of the lead plates. No chance to revitalize by inverse charging at the batterie's end of life😂

How come if you hook a smart charger to a really dead discharged battery, it will show fault but if you connect an "old school" charger to it for even a few minutes, you can charge it using a smart charger? My son ran the batteries down in his Razor go-kart to almost nothing. These are actually fairly new batteries. I picked this go-kart at the county dump. All that was wrong with it was the batteries.

When I connected the dual charger that is actually used to charge the batteries, the indicator on the charger showed green as if it was charged but they were not.

I disconnected each battery (two 12 volt batteries hooked in series) and recharged them one at a time. The smart charger showed a fault. The old school charger showed about 8 amps. After charging the faulty battery a few minutes with the old charger I was able to hook the smart charger to the battery that showed fault.

interesting to see it worked... but the REAL hero was that starter motor.... I was waiting for the starter to burn out...

Wowww, amazing tought and job sir..i was just looking for fix my battery Bosch 12 V 100Ah dosnt charge..hoop it work for me too..thanx and have a great day..without cold wind..lol

Wait, all i've learned is fake ? :o

Excellent video 👌

Can't trust Russians

this brings up an interesting point, if electrons flowed from negative to positive, you would simply be able to reverse polarity of dead batteries to have fully charged batteries, how is it man has imagined two types of electricity (- and +) there are not two types of electricity, there is only charge✊and discharge🖐

Very interesting!

Very cool 😊

Leave it somewhere for the porch pirates to find and then watch the show

"Until, in the midst of my darkness, a sudden light appeared. Change the poles from plus to minus, and minus to plus. I alone became capable of bringing back to life, nay, even more. I alone became capable of bestowing life upon lifeless matter."

Wow, thats suprising. Great work. 👍

Not

That was reversed polarity

Try to reverse it again, no desolfation is complete.

👏👌👍

Will this work on calcified battery?

Adter all those test, did you tryed to revert the battery to the original polarity to see the performance? Thank you!

Thats a good starter 😂😂😂

Charge at 15.8 For sulfication of cells.
Boil batteries.

Incredible! I will be doing the same to my battery pile..

What model is that Toyota? I see it has the same 4A-FE as the corolla

if you have problems with the battery, the best advice is to buy a new one!!!😢

Perfect 😂 Goodyear job.

Ok, hang on and time out!! So, are you saying the way to restore a battery like this is to reverse the polarity in the charging and then...when its complete, the negative will now be the positive and vise versa?

I would not have believed it.

Sodium 🧂🔋 say good bye to lithium ion battery

I didn't know that was possible. But then again, nothing is what we think it is! NOTHING!

An old timer once told me this. I was skeptical. Never tried it myself. Never heard of anyone else trying it either. Good to know he was spot on.
