Sealed Lead Acid Battery Recovery / How to refill lead acid battery 

Refreshing to watch a tutorial that isn't just "Do this one simple thing to fix". Informative but realistic. Thank you

I want my eleven minutes back please

He is like a doctor trying to recover his patients

Thanks for the video, I know it´s an old one but just wanted to know how you got the charger working on a battery that has less than 1 v , supposedly the charger needs at least an 8 v reading before it can start to work.

So video didn't show justice to the caption. Wasted my precious 11.06 minutes of life.

Thank you very much.

after watch this video, I decide to buy a new battery..

Very good video. Excellent production value and information content. I learned a lot. Thank you for pointing out the age of the battery as to be considered. Other videos on this same topic did not mention the possible fails as well as yours.

The was deposits in the bottom of the battery. You should have checked resistance of each cell and also rinsed the battery out first. Then refill and charge

Thanks for the video mate. Very informative. God bless you!

Battrey life is 5 years only my friend ,we have to remember this

How do you check how much acid or distilled water is left in the Battery before you start refilling it. The hydromers for cars are to big. Please advise where you obtain such a device from and how much they cost in UK sterling (£) thanks for your help .

Thank you 🙏🏼

Thanks.... I got the same charger. I just drilled a sealed lead acid 85Amp & topped up with distilled water & is now charging via pulse repair. When unplugged after a couple of hours voltage was 13.1Volts so I'm continuing pulse repair looks like I have restored it. I will use hot glue to seal the holes & which will be easy to remove for a further top-up. The sealed batteries can be brought back if you can get water in.

Hello . I did same to you and i got problem you know the ruber black caps . i have all blue but my problem is the plastic x-x did come with my blue cap . is a ways to plug the hole after did fll up water ?

I have the same battery size that was manufactured in 1999. It had been sitting dead probably since 2005. I did the same procedure as this guy did except I added 20 ml of sulfuric acid to each cell and the rest with distilled water. I did the pulse repair for a few days and it was worthless. I got 12v and maybe 70w/hr for all that repair. Forget the pulse repair hype, they are worthless. I had purchased a bunch of VoIP phones from a failed business in 2008 which had plug in wall adapters that would produce 26v at 2amp. I connected this power adapter to the battery along with a voltage meter. For 24 hours I was getting a voltage reading at about 25.9v. Several more hours later, 2 or 3, I went back to look at it again and the voltage had dropped to 20.1. Before I went to bed for the night, I looked again and the fuse had tripped on the power adapter. Voltage meter now reading 5.72 volts. I went to bed. In the morning voltage was down to 3.1 volts. I connected up another power adapter to the battery for the total count of 2 power adapters connected to the battery at 26 volt. That brought the voltage back to 22.2 volts. 12 hours later it was down to 21.5 volts. The next morning, both fuses had tripped on the power adapters voltage at 4.45 volts. I reset the trip fuses and turned them back on. 15 minutes later I went to check and once again both fuses had tripped. I have a 200amp car battery charger that would start a diesel Mac Truck. I connected that up. It was pulling more than 40 amp. 12 hours later, I went out to check and disconnected the car charger. It was maintaining 11.1 volts. I did a discharge test and got 3150w/hr. I plan on doing a few more fully discharge and recharge with 200amps. I fully believe that this battery will come back to life.

Hello need help asap So i was able to revive one of my 2 SLA battery. The other has a problem because one of the 6 cells inside is reading 0.2v but the other 5 reads 2.0v. How do i fix this?

Beautiful

You allowed the battery to reach a normal voltage, but you have no amp hours. This can breathe a little life back into an old battery, but will not bring back the capacity of the battery.

Nice 👍👍 🇮🇳 || Kuki

I restored my battery with this guide BUT my batteries stay horizontally, not vertically inside the scooter and some liquid was spilled as the rubber caps cant keep the liquid inside. Question: can I permanently put some glue on the holes and seal them shut so there wont be anymore spills OR it releases gases and it can blow due to creating pressure if I seal the holes????

Desulfide the surface of the battery plate first by using crystal soda and hot water to neutralise the sulfites and empty out before re add battery acid and re trickle charge

Wow.. you don't seems to understand a single basic fact in this instrument. 1) This is both repair and charge unit. 2) With repair mode, this unit will desulfate your battery. On the way, it will charge, but not necessarily enough. 3) Battery with 0.3V is almost dead and will need lot's of desulfate process. i.e. You will need to repair it for couple of days. 4) After couple of days of desulfating, you will try to recharge it (not the same as repair) 5) If no good, then I would discharge the battery and try again to repair it with high voltage repair pulse feature. ps. I wouldn't have voltage meter on battery while repair it.

Could you please suggest me how charging unit needed for 12v/4ah battery. Please I need your help

Once a battery is recovered, what is the run time vs a new battery the same size?

Thanks for the information ♥ ️ I have a problem with this charger and I lack experience. Can you help? ♥ ️ ♥ I put maintenance and the operation was successful, but the problem The battery is empty of charge 0/100 and despite long hours in this charger does not exceed 20/100 what is the solution

Why the voltage gradually decreasing?

Can use normal battery water?

How do you discharge the battery @2:26??

Sir pwd b gamitin yung nbibili sa hardware na tubig ng batery galon na puti

You need to add acid,only water will not work for such old batteries.

Just a note to everyone who doesn't realize this. Even if the battery was able to be recovered, it has to remain upright all the time. Boosters use VRLA batteries. As such, those have to remain sealed because I'm sure that they'll get tossed in the trunk when not in use. The moment you tear the plastic lid off, good luck keeping it sealed.

I personally think is a waste of time using Epsom salt and water I think it's best to crystal soda and hot water to desulfite the plates a few time before refill with it's own acid and trickle charge

Can i use battery acid

150Ah battery can recovery for this..?

is battery water the only important thing to put in the battery?

Pwde lang ba yang ganyang batt for tricycle po boss 12V / 7ah siya pwde lng b sa motor yan.?

sir pede p0 b mag p repair ng e-bike battery lead acid 48volt 20ah saan p0 kau lugar ppuntahan

You cant say you're recovering the capacity of a battery if you don'trun a capacuty test at the start and at the end

How can I charge this battery with Solar panel and also how can I protect it from overcharging through solar panel?

Come si chiama la bottiglia per caricare la batteria

HAHAHAHAHAHA Made me laugh in the end. Maaaan. That was so realistic.

I use new orriginal fluid to revive batts works much longer

2.05 for safety: Wear safety gloves. Both hands are equal, especially the left one so when the boot is on the other foot, obviously the left glove protects the right hand. OK Gottit, makes perfect sense ; )

Maganda at impormative pero kailangan magsalita ka rin para lalong maunawaan. txn

when repair battery need to wait 1 day until the pulse sign turn to full sign

I don’t understand. At the end you say that it was “far too gone” but then say later that it was revived.

The definition of regret is watching this video

sir gudam pede p0 b mg p repair ng e-bike battery lead acid 48volt 20ah saan p0 pede kau mapuntahan salamat p0

I charged my battery is with closed holes....is it bad to my repair?( please reply please)

is it distilled battery water

Were is haveing lead acid

Needs to be charged in parallel for it to have any chance of actually retaining anything

Same music everywhere.

When i connect mine to another battery, the water boils?

The only thing I found useful is "safety first" 😂 shitty recovery. He needs to drain all the acid from the battery first then mix fresh 80% distilled water to a 20% ratio of sulfuric acid. (that's why it's called a lead acid battery) This guy is misguiding people. Please don't follow this. He needs a 200amp charger to charge for a duration of 2 hours and then wait for 1 hour to cool down the battery after which he needs to repeat the process of charging for 2 days it's a lengthy process and takes time but the results are good. People with half knowledge do this like this and mislead people for views and likes. 80/20 ratio is important else it won't work. It's like having only water and no food to give you energy ⚡.. 😂

From where should I buy the demonized battery water's please let me know you're reply as soon as possible or please share me the links to purchase

The video is a bit stuck. Like a DVD, there's some prob.

How many ounces of lead could one recover out of that battery?

I m charging my 12v 7Ah batterty with 14v 7.5 ah charger… battery is charging up to 12.60v but after 3-4 hours voltage decreases (10-11v) without use. What should i do?

how come I watched for 11 minutes and the conclusion is unable to recover...

Do it 5 hours for repair time.

Never use steel needle

So the whole video you basically did nothing. The battery was dead and remained dead. Your biggest problem is the filling of the battery. you need to put the needle deep into the battery and fill a specific amount usually about 10 - 30Ml per cell and let it soak in. Then charge the battery. your watering didn't do anything.

12v ki battery ko 6v ka bna diya

You can not restore it.. don't put liquid or water into AGM (absorbed glass mat) battery which uses PbCaSn alloy for plate grids Details: An AGM (absorbed glass mat) battery contains a special glass mat separator that wicks the electrolyte solution between the battery plates. This material’s design enables the fiberglass to be saturated with electrolytes - and to store the electrolyte in a “dry” or suspended state rather than in free liquid form. As the battery works, the electrolyte is transferred from the glass mat to the battery plates as required. The mat contains enough electrolyte for the battery to deliver its total capacity, and - should the battery case become damaged, or the battery is tipped on its side - its electrolyte will not spill.

I wouldn't recommend taking a lead battery apart there sealed for a reason.

I'm thinking lead acid battery doesn't work that way.. sometimes they will fail overtime and lead to expire battery but good try

you should use acidic water, like lemon water and charge it with high voltage, like 30v and charge and discharge using halogen lamps, it's a long process, for me, it takes 3 days to recover

You have failed. Lol You need acid water not distilled water, there nothing to ionized in empty water.

Z

Don't do any of these, just turn the battery upside down. Because The electrolyte settles down due to usage thumps and gravity. 🤘.

Buy 5 batteries instead of these craps

Non sense kuch bhi nahi he iasme bus time pass he

Ha ha ha. I wasted 11min

you can't talk?

my led battery light is not working , lets check if video helps lol

Absolute crap.

These Charlie Chaplin (silent) videos just SUCK!!!%

waste of time ..dislike
