Battery acid leakage
Just curious as this can probably happen from time to time and is normal.
I charged my batteries up and for the first time I notice two spots on my concrete floor from acid dripping through the drain holes on the bucket. I looked and it was the two batteries on driver side, (4) 12v batteries. I looked and it seeped out of the factory caps on my U.S. batteries. I know they don't make a perfectly tight seal and the batteries were at proper levels and not over filled. I just have never noticed it doing this before and would like to know what you guy's think. |

Re: Battery acid leakage
you will get a little seepage when charging batteries that are above the fill line , i know you said not over filled , they will bubble while charging .. caps are not air tight to allow gasses to escape , so a little acid will splash on caps and leak out

Re: Battery acid leakage
I have seen a little acid near the caps in the past charges but never to the point to cause leaking down the side and through the bucket drain holes. Maybe it was a longer charge cycle and those two batteries were fully charged before the other two and from boiling longer caused this, thoughts?

Re: Battery acid leakage
that's a possibility, i would go check the water levels on all the batteries

Re: Battery acid leakage
Just read the thread below and use the same type of bottle. Maybe it has over filled a couple cells just enough to cause the leakage issue I had.

Re: Battery acid leakage
As my batteries have gotten older (AKA really old and clearly losing storage capacity); I've had to add water more often - and each time I add, some cells are much lower than others. PLUS a number of the batteries are showing wetness on top after charging, and they never used to.
I have rationalized that its due to uneven battery capacity due to some batteries performing more poorly than their buddies in the pack - so some cells are called upon to take more than their equal share of "pressure" from the charger until the correct pack voltage has been reached. |

Re: Battery acid leakage
Important thing is to never fill the batteries before charging. Always fill them after charging. The level goes up when you charge.

Re: Battery acid leakage
I've seen the seals on the caps go bad. You may want to try switching the caps and see if the same ones leak on different batteries.
