Wear gloves and eye protection when working with opened lead-acid batteries. The lead is highly toxic and the acid is bad as well.

That the voltimeter indicate 13.3 volts for a battery of 12vdc 7 AHor 9 Ah, it doesn't implied that the battery is working. If you want to check it you have to add a ligth bulb of 12v 50 watts as a charge and after that you have to check that the voltage is more than 12 volts. Probably for low charges as a led light tube it's working.

I like how you tip battery acid over your hands. God bless India

Step by step is ok but must take the reading of each cell after the initial charge. All are same or near and the battery can be revive. Especially if it was used to its expentacy period.

Impressed , how long will it hold its charge.? Will this work on an e-bike batteries 72volhts 5 is alot of cash for 5 new batterirs .

Don't shake that crud out onto your counter top/workbench, it is very corrosive, shake it into a big plastic bowl

It appears that the lead plates on that middle cell have deteriorated to the extent that they have dissolved, thus the black residue that has been flushed out. This will be the weakest link in the battery, it will overheat under a charge as well as a discharge cycle.

Wow i have several i can try and after 34 years as an auto mechanic and tought auto for 8 years cant believe there are no warnings on how dangerous battery acid can be or damage it can cause after anything is exposed to it and after just a minuter or two with battery acid on unprotected fingers will start to hurt or burn within a few minutes and you get it on your clothes they appear fine till you wash them and then they come out of the wash with holes from the battery acid just one example of what battery acid can do and can be very damaging to your eyes. To anyone without knowledge or experience with batteries and battery acid the lack of warnings seems very much like dereliction of duty as a teacher.

The bottle says water but is it actually battery acid or distilled water? I thought these batteries use a gel e!ectrolite.

Good job with all the best information and knowledge

Very useful but cannot stand the background noise that's supposed to pass for music.

Idol pareho lng bayan Ng rocket na 100ah

За три часа он не зарядитися, я купил один такий в метало базе на нем было 8 вольт я долил немного дистилята и каждый день у меня он заряжался он 6-7 часов, наночь оставлял чтобы простоялся и так через неделю он востановился напряжение 13,7 вольта ❤

I do the same only I use electrolite out of an old car battery works really well

Eu já fiz o mesmo mas utilizei uma seringa para encher novamente a bateria

just wash it, fill it and it's done.. There was no salt and lemon like in the other video... Good clips Bravo

All that violent shaking will destroy whats left of the lead plates..putting a water jet up there might be better. Its not gonna last long after that repair but it will get sold as it will show full charge

I tested the washing up and made a short charging of half an hour in 2amps. It seems that works since i used the battery in a small compresor that takes 2.5 amps and yes it worked for some time. I do not understand why you have to wait 2 days to refill the battery with distilled water. Is there a reasom for this? Also did not understand the use of tube at the negative rail. Is this for degassing during charging?

Thank you for your great video

Thanks a lot ❤

Will the hot water not cause short circuiting in the battery terminals?

great work 👍👌💪

Very very super good idea thanks for you

Love the video and music. Keep up the good work. People that don’t like the music can just turn the volume down. Your not talking anyways so what’s the big deal?

Would putting the battery upside down in an ultrasonic cleaner work ?

Nice work

Excellent production (but for the music 😏 )... But could I stress health and safety most be observed.. The use of gloves and safety glasses would be advised..

Thanks for the video How can u repair 10Ah/12vdc powder battery

Very nice and useful

Very good friend

Просто для ясности------это всё те же по конструкции аккумуляторы, что стоят у каждого в машине под капотом к примеру. Только малых размеров.. Делайте правильные выводы.

خوب بود ایکاش با توضیح بود

That music is enough to drive a person insane ...

Why did you put the bicycle tube seals on only three of the battery fluid openings, and caps only back on three? I thought you were going to use those to seal all six openings.

send this guy a eye dropper

Please give us information, no bad music.

Good work, and good idea

this is wonderful I now get 24 volts from my old battery and it hasn't gone flat for over a month now fantastic.

Hi….. You added only destilled water? No sulphuric acid?

Worth a try but using saftey gloves and eye protection.

Das geht destilliertes Wasser und Salz und Zitrone Aufladen vertig

primer error , utilizar una jarra metálica. se debe utilizar agua destilada y una jarra plástica. o se pondrá en corto circuito.

You need to mind the acid buddy. Be careful. Feels like water but will continue doing damage. Put a drop on a pair of old jeans and check it a few days later.

Slow 2/3 amp charge will be gentler on those compromised plates

Nice work but remember to wear safty glasses and ate least groves next time safety first

What sort of charging device did you used to bring the battery up to 13v.

Dapat bro, mag tutorial ka para mliwanag dapat walang background para mdaling maintindihan

Szia érdekel hogy evel az eljárással lehet e el. Biciglit hajtani?

thanks

Ty 🤙🏻

OK good thanks

I basically had the same problem with my battery. Last month when I was on my way to the store, my car died so I got my multimeter out and I checked the voltage on the battery and it was 9.7378 Volts so I thought “what the heck is going on with this battery”, the next thing I knew I seen some smoke coming from the tips of the battery terminals. I was suspicious on what was going on and I couldn't believe it because this battery was only barely 16 years old which I consider fairly new in today's society, so basically what I want to do is try to clean up the battery with some soap and salt solution and then I might put it on the charger for two or three minutes at a high current rate just to see if it will hold a charge. I'm not sure if that's going to help the battery or not but one thing's for certain before I go out and buy a new battery, I'm definitely going to try these two methods that I suggested. Now on the other hand I could swap the battery out with one from my 1962 Chevy Tahoe but I'm not sure that my old lady would let me do that, so basically what I need to do is first, I'm going to check all the air in the tires before I monkey around with the battery. Then I'm probably going to run a few errands around town down and the next thing I want to do is get some paint and paint the battery terminals because I don't think they look very good without the neon yellow color look on them. If all goes well, I am planning to do a few other things to the terminals. Next after that chore, is get some of that distilled water and pour on the outside of the battery to try to clean up a lot of the dirt and dust its accumulated over all these years. If I have time what I'll do after that it's try to clean both sides of the mirrors on my 1965 Ford Bronco because I've noticed while I was driving that it's hard to see what kind of traffic is coming up behind me. I was having a problem with the battery when I put the headlights on low beam and then when I tried to switch the high-beam I noticed that the voltage excursions were jumping around so I went out and I bought another set of test leads to use on my digital multimeter and there was no difference at all, so I think I may borrow my friend Tony Jones's multimeter just to check those voltage excursions to see if that is normal. Nobody really explained to me how to test a DC voltage excursions when the battery is not in its prime. I am all on my own doing this. A lot of people have contacting me and they said that they've had that problem once or twice and maybe even three times in their lifetime with their batteries but they did something totally different. What they did was loosen the terminals first then they carefully remove the battery and hoisted it out to get rid of all the debris and dirt that's accumulated after all these years then they put it on a slow charge which I believe they told me was 32 milliamps for 6 days, 3 hours and 54 seconds. Next they took the battery caps off and added some distilled water, which they claimed that they bought it at their local Walmart store. I think, if I can remember correctly, they said it was .99 cents plus the sales tax. Can you believe that just 99cents? That's a real good price for one full gallon of distilled water. Speaking of water, yesterday I helped my neighbor that lives to the right side of my house, fill their swimming pool for the new season. It literally took 7 hours to fill. I am not sure how many gallons it is. I have met people in my lifetime that had no idea that there were 4 quarts of water in a gallon jug. They just assumed it was a gallon only. I am not really good at math but I do have a calculator on my cell phone. Speaking of math, it takes me back to grade 11 in high school when my teacher, Mr. Lowry gave us a sneak quiz on algebra. I failed it because I didn't understand what that was all about. I spent most of my high school time stoned and kind of out of it. Some of my classmates were very good at math, and it even showed when they got their report cards. I may have gotten of the path of whatever we were initially talking about. I think it had something to do with blue cheese. No, I remember now, it was car batteries. I never could figure out why they put car batteries in the front of the vehicle and not inside the vehicle. It would be so much easier to work on them, especially in the rain, if they were inside the vehicle. Doesn't that make more sense to you too? Well anyhow, batteries are pretty heavy for their size and some people can't lift them very good. I had a fried, Tony Smith who had asthma and once he tried to lift out his car battery, and sneezed, and the battery fell out of his hands and landed on his right baby toe. It broke the small bones in that toe of his. I called his mothers step daughter Ann but she was not home. So I then called his brothers uncle Fred and told him about what just happened to Tony's toe. He seamed like he was drunk and started laughing at me and said “I don't care about that Bast#rds toe”. I got mad and hung up on him immediately. From that day on, I never spoke to Tony's brother's uncle Fred. I never really liked him in the first place because when Tony and I were 13 years old, we were at a softball game and Fred walked over to us and farted right in our faces. That was not very nice of that old pervert. I heard some stories about him when he was about 20 years old that would make you cringe if you heard them, but I can't get into that right now because I have to finish up my posting here on you tube. I hope I have given you folks some good advice on having some of your problems solved in a timely manner. I like to help out when I can if it is at all possible. I am out for 3 more hours so I want to go now and get a hot dog and a bottle of grape soda. I need to look around for a ride so I can get back to my padded room at the Sinclair Insane Asylum. I hope Dr. Dilbert will not be mad at me for sneaking out....

For effective repairing change all plates with new one

I couldn't watch because the "music" was driving me INSANE

IF YOU USED BATTERY WATER,,ISN'T BATTERY ACID,,,THAT BATTERY FILD BY ACID ,,AM I CORRECT ,,???..

After the renewal, how long does it last ?

You have certainly recharged your battery but that is not remarkable. With no information about the battery type, its capacity when new and its capacity now, you show nothing in numbers to support your claim to have "repaired" the battery.

Sure you can put a small surface charge back on a dead battery. But what is it's total capacity? It sure won't be 9 Amp hours, probably much less than 1. Also, a new battery of that capacity can actually start the engine of a small car. I bet that one can't. Its internal resistance will be way too high due to plate deterioration. I played with this sort of thing for months, and once the plates have been eaten away or heavily calcified, the battery is simply dead. It's easier to build one from scratch or just go buy a replacement.

What about asid ? How do you explain it and how you lightning the LED without charging the battery ? 👍

The background music was so bad that I actually felt that the battery should have been blown away with a 12 gauge shotgun beyond recognition.

Buen video pero siento que falto explicar esa parte

What is battery water? Is it distilled water? Does it also have sulfuric acid in it?

in many countries that care about the environment, it is difficult to buy battery acid

Good work but a very slow video

Seen distilled water been put and then charged well how does this work without acid involved.

Cool video but that music is annoying as hell

it seems to be good but the accumulator water was only destilated water

LMAO, "Battery Water", what a harmless sounding substance. Anyway, that dark stuff dumped out of the battery with the water is Lead(IV) Oxide. That is what the positive plates of the battery are made of. That battery is no longer serviceable. Just replace it with a good battery.

That's the very next step to save $9 dollars on a new battery on the corner store

Can u help me please ? Even i got a battery name Eaton i can use for it pls ?

Nice music

Same lng ba Ng maintenance

Is it one battery or two separate batteries? The color is suspicious.

Where do the red and black crocodile clips come from??

I've tried flushing out an old battery to get rid of plate residue that can cause shorted cells. Wasn't very successful and the capacity will be degraded.. Scratch that one!

Thanks a lot.

is it a distilled water (battery tonic water) or a pure acid of battery?

Video good. Music bad. Please pass on the music next time. It distracts from the video.

Tebrik ediyorum helal olsun

Nice video :) thanks.

dang you crazy man! no gloves or ppe? wow...

Why did you not add any acid back in, just distilled water?

This is very dangerous! Do not do this! Plus putting a volt meter on it without any kind of a load on it does not mean a thing. Put a 9 amp load on it and it would probably drop the voltage down to almost nothing.

Yes, other methods are given on several videos. But this one is the best. And nobody used Hot Water to drain out the dirt and residued collected in the battery over time. Yes, there is a limp on this video.The battery was charged for three years; with what kind of device or charger The ratings should have been mentioned about the 3 hours charging. More or less this was a good video. Thanks!

على ماذا تحتوي هذه القارورة البلاستيكيه هل على ماء مقطر أم على أسيد البطاريات أرجوا الرد

can i use for my computer

In my case, the voltage drop quickly. Can this be repair?

Funny how the gray battery becomes brown then gray again, and the markings on the original top don't match the final battery weird, no?

Voltage alone says nothing. What is the capacity, or in it other words how long can it support a load. Probably far from the 9 Ah labelled on the outside. In order to really „repair“ the battery, you need to deconstruct it, make the internal cells new and put in back together. Those guys from Pakistan do that all the time and have many videos on UKposts. Simply exchanging the water will help very little, if anything.

HELLO DEAR IS PANI KON SAY DALNA HAI BATTRY SHOP SAY MIL JAI GA ?

All you need to do is paint it black -!- will work forever-!- than find one of your buddies with that shade tree -!-

Thank you

can use long long time?

Dear sir, how to dispose the acid contaminated water you removed washing after clean that cells, can I flush in go toilet?

Hy i have a problem with regulator i can't connect it 3 yellow wire , black, green,red

Why using cycle tubes

First video of repairing a battery that shows them putting in new acid

What kind of paper was that you cut off round??🤔🤔

Sou Jailson quero saber que produto coloca nessa bateria 🔋

Bonjour svp j'ai eu une batterie solaire (12v200mh avec 2 panneau de 200W ) de marque GLT , elle se charge pas comme il le faut , en pleine journée la tension tourne au tour de 12,3v cette tension chute au fur et à mesure que le soleil s'incline à 18h je peux me retrouver avec 11,9v au petit matin tout s'arrête pourtant j'ai 5 lampes de 12v ( 3 de 9w et 2 de 7w) avec un petit écran LED de 26 pouces
