If you hear bubbling, likely you are overcharging the battery and may have damaged it. I would start by checking the acid levels and add water if needed. (Use distilled if local water is even a little hard. Note: spring water is NOT distilled and likely is worse for your battery than tap water.

After getting the fluid levels right I would bring it into an auto parts store and have them test it.

Good Luck
