Lead acid battery boiling during charging: this is bad, right?
The reason is that lead-acid batteries normally form bubbles on the plates during charging. And these get big enough and then rise. Some chargers will periodically reverse the charging voltage polarity for a moment in order to force the bubbles loose so as to keep them small, as the bubbles interfere with re-plating lead from solution back onto ...
