What does it mean when a battery boils?

Hydrogen gas, when combined with oxygen from the air, is highly explosive and can easily be ignited by a spark. Yes. You shouldn’t boil them.

What happens when car battery water is low?

Low water level means the electrolyte will be out of balance and the battery cells will become too acidic resulting in sulphation on the battery plates. The non-conductive lead sulphate crystals will hinder flow of current through the electrolyte.
