Thanks for the info. I've got an old Yale forklift that's been sitting for a long time. I'm working on slowing bringing the battery voltage up. I started at 7v and now I'm at 31v with the charger disconnected. Lot's more charging and desulfating to go. After I've run it through a few cycles I'll probably have to adjust the electrolyte mixture a bit. It has a watering system but it looks like it's been overflowed before, so that'll probably get replaced.
@@graphicsequip7863 I didn't add any acid. I got the battery working but unfortunately one of the cells developed a short. It took about a week to charge with the charger I was using.
What purity of sulfuric acid do you recommend using. Obviously not fuming but are you using battery grade 30 to 45 percent sulfuric acid or something stronger?
Hey, I have a question. What would happen if I use common lithium batteries like 100amp 12 V or a higher voltage battery to make the voltage that was required. What is unique about forklift lithium batteries that are different from the ones we can buy off Amazon? What are the potential hazards of using the common large lithium battery array?
i would only add more solution of sulfuric acid if the battery have gone through a 24h or 48h desulfation and the specific gravity readings were yet as low as 1225. That would indicate that the battery possible fell down and lost a little of its solution (which usually is the case with those tall and slim 48 V forklifty batteries) or that it is too old (deep cycle batteries here usually last up to 5 years, if well cared and kept).
Thanks for awesome video. I did everything you said after watching your video. All the reading are good but after couple minutes of use forklift bugging and start cutting power and dies. That I put the 3x12volts car battery too bring it back to life and it works just fine with car batteries. What do you think the problem might be? Thanks in advance
No it doesn't. If you think you have a blown fuse in yours it will be one the links is broken. Also one of the posts could be cracked under the plastic or under a link
Call battery shops in your area and ask them if they sell battery acid "sulfuric acid" or if anyone else sells in the area. I purchased a 5 gallon jug for $30 US dollars
Like your video. Where to buy the sulfuric acids ? Liquid vs powered and difference ? I added water already. Can I add acids after or should i remove a little bit of the water ? Thanks so much.
@@siduolocin I'm in the states. I found lab grade sulfuric acid but I'll continue to shop around and see if I can find some that's a little more affordable. How much acid did you need for that battery?
Daaaaaamn . . . You actually pulled out a 2700 pound battery with your hands? That looks like 18-125-17 battery... Man, my back hurts just by watching you...
That battery is toast, these batteries will only last 10 to 12 years at most, what you have done is a waste of money, scrap the battery and get a new one
They are called CELLS not battery All the cells together make up a battery.... Batteries don't last 20 years or more. Most forklift batteries last 5 to 10 years. You do get the odd one every now and then that may reach 20 years but its well and truly stuffed by then. 99% are pretty stuffed even at 10 years. What limits capacity on an old battery is sulfation that grows on the lead plates. This is the main failure mode and adding sulfuric acid wont fix that. It might raise the terminal voltage a bit but wont give any extra capacity. That battery like most forklift batteries is designed to give 8 hours of operation not 4. Your video might give a few tight arseses that warm fuzzy feeling inside thinking they might save $8K (actually $5.5K) on that battery but the truth is it will save them nothing and then they have to buy a battery for $6k
Anybody that knows anything about forklift batteries knows that you didn't do anything, you did not repair that battery, all you did was put some New battery acid in If that improved the battery then there was nothing wrong with the battery to begin with. Just low on electrolyte.

Awesome video. I appreciate you streamlining the process as well as the specific instructions at each step. Thank you!
Very good information, great guy
Do you have the link for the battery acid? Thanks
What do you use to remove electrolyte to add more acid if the the cell is to full?
What purity of sulfuric acid do you recommend using. Obviously not fuming but are you using battery grade 30 to 45 percent sulfuric acid or something stronger?

Bro this is a lead acid battery , you need to do alit more research before doing anything .

Thanks in advance
what concentration of sulfuric acid did you use?
Where can I buy the acid
Can you do the welder technique on batteries like this? Attach a welder for 15 mins on?

Does that battery come with an internal fuse? Thank you 🤓
No it doesn't. If you think you have a blown fuse in yours it will be one the links is broken. Also one of the posts could be cracked under the plastic or under a link
@@microwave-vh2uc thank you. Have a battery powered pallet jack with the battery not charging. Thank you 🤓
How strong are your sulfuric acid soluton??.. here in Denmark I can get 14%, 20% and 95%

Where did you get the sulfuric acid?
you from australia? try www.netra.com.au

@@siduolocin hey mate do you know what brand and concentrate you used and I guess where to purchase in Australia?

He used a forklift to pull it out......
Hi I want help

If you have LFP battery forklift? Or who knows where I can get it from?
When mixing electrolyte, always pour acid into
water - never pour water into acid. Pouring water into acid will cause a dangerous chemical action.

Believe it or not I have a 42 year old Nissan 1.5 ton forklift that original battery’s are only recently gone
You doing that while it's charging over 232 volts when adding the sulfuric acid There's a rule of thumb to acid adjusting a lead acid battey
