Here is a video showing how to open a sealed flooded lead acid battery so distilled water can be added. Be careful when opening any battery.




I have another for SLA gels coming.

If I didn't say thank you loud enough;
Lean towards your window, you may hear me!

THANK YOU!!

Just re-filled both batteries!
Simple when someone tells you how.

May I ask, hopefully without hijacking the thread...
If, indeed, these batteries are sulfate'd, as folks suggested,
I figured I'd see something while re-filling.

Looked pretty clean in there... but, then again, haven't a clue what I'm looking besides crud..

Nice video,
Its good to wear eye protection because usaully theres always some droplets flying around when you pop that cap out and you really dont want that stuff in your eyes.
And what he said at the end is also very important...rule of tumb is 10mm above the cells.
Have work with forklift using massive batteries and it does happends that someone over filled it and put it under charge...oh boy.

Hi ODR

What you will see is a light gray to a dark brown almost rust and see how that works

Thanks guys! Glad to have helped. Its way more fun than arguing with Mag! (LOL , just kidding Mag)

@ ODR : You may or may not see anything in them. The sulfation will be between the plates. I have overfilled them and made a mess more than once. None of these batteries should be too far gone to save. It may take some time to desulphate them but its worth it. You nice big machine should have no trouble bringing them back to full power or very close to that. I have one I have been working on for weeks now. Some days I just don't get to run cycles so it makes it take that much longer.

@ IAEC : Thanks. They do make a large mess when they overflow. I get mad at myself everytime.

Doug, I used a piece of white paper to dip in there to see what I'd pickup. Little bits of debris, but nothing more than what I expected. My good batteries do the same. I may just have some hope for these!

Fan, I'm pleased to hear even if I did somewhat sulphate them, I can get them back.

All in all. A Good Day!

Hi ODR. The SLA gel cells are the ones I have the most trouble with. I have fixed one or two but usually they have been left on a charger and cooked dry. After that there is not much hope for them. I have fixed two that were dry. Do not hook a dry one to your big machine first. When they are too low or have been dried out the voltage spikes up really high and can damage your machine. Try them on a small machine and observe the neon. If it doesn't light on the small one you should be able to put it on a bigger one.

Hi fan and ODR

I use a little 4 transistor and turn the pot to its max about 100 ma and just let it cook 4 or 5 days then have a 1.2 amp light and drain it to -0- and then charge again but this is only if you exceed 18 volts at start up and it stays there. This a drastic step so make it a last resort. I call this SHOCKING and I am doing this with one now on its 3rd time.
