> Electrolyte at proper level, and shall have the correct value of specific gravity by checking with a hydrometer.
> Rubber gloves and goggles used when handling electrolyte.
> Charging equipment checked for dirt, overheating, loose connection and correct functioning of indicators.
> Ventilation arrangement for battery locker checked. Battery installation of both lead acid and alkaline needs good ventilation.
