hey
im trying to charge a battery off a 200E that sat in a heated garage all winter but was wound over until dead. I plugged it into my canadian tire charger and after about 15 minutes I herd bubbling so I wasnt sure if i should keep boosting it or not. I herd something about backing the yellow caps off so hydrogen gas doesnt build up then have an explosion. Is there any truth to this. If not tell me the proper way to do this.
