Question

DentroTest · Accepted Answer

In batteries that require maintenance, it is essential to check periodically the level of the electrolyte (a mixture of distilled water and sulfuric acid) that covers the lead plates in each of the cells. If the level drops through evaporation, it must only be topped up with distilled water, never with tap water, since its salts and minerals would irreversibly degrade the battery. Likewise, the terminals must be cleaned periodically to prevent the formation of whitish sulfate, and protected with a thin layer of suitable grease or petroleum jelly. By contrast, the vent holes in the caps must never be blocked, since they allow the gases generated during the charging cycles to escape safely.
