Battery Boiling When Charging??

lubben810 · 01-29-2008, 06:04 PM

Lat night when I put my cart on the charger, after about 3 hours I could smell battery acid and when I looked at my batteries, half of them were boiling out of the top holes. The charger was at 0 amps so Im assuming that it meant the batteries were completely charged. What causes this? Is there just too much water in the batteries or what? They are only a year old Im told.

Could be a couple of things. To much water in the batteries. The charger isn't cutting off like it should. You have a battery or two that is failing causing the charger to boil the rest of them to try and make the one or two other's fully charge.
Take some voltage readings about 30 minutes after you finish charging them. Let them sit and cool off first.
You didn't say what voltage the cart is.
36 = 42-44 volts after charging
48 = 52-54 volts after charging
