I thought id be a hero and add some distiled water to my flat battery and then hooked it up to my charger. 15 hours later, there is some water on top of the battery and a bubbling coming out through one of the screw holes.

There is no noticable bulging. Is my battery worthless now? Im not sure if I overcharged it or I added to much water.

Normal dude. Will bubble when being charged

Hydrogen gas produced by charging process. Be careful of flames/explosion.

yeah could be a good idea to remove the caps.

got a way to siphon off the acid? bring it down to where the plastic tube ends.

Once charged they should all bubble at the same rate. If one bubbles and the others don't your battery is probably stuffed from being discharged too much and too long. Once charged let stand to let all the bubbles up, and check with a torch, NOT a match! Even out all the fluid levels by transferring fluid from overfilled cells to others.

Could also mean that you are charging with too many amps I think?

normally if bubbling over too much fluid or too high a rate of charge for too long
do u have a bad egg smell???

you should be charging with the caps off. I know i used to work with century batteries, copped an awesome burn here and there from those damn things

Haha Lynel i was a sales rep for Century batteries in tasmania a few years ago, Yeah bubbling is normal, just make sure you charge with the caps off. A good sign of a battery being over charged is the outer case will be swolen.

i got electricuted a few times aswell haha we would switch the charging tables off and because of the configuration of said tables there would often be inductence in the lines from the other beds and every now and then id have to pick myself up off the floor hahaha fun and games

HoHum - so much for safety in the workplace! :facejump:

we change batteries while the cars are running so we dont have to go look up the radio code...
