Replenishing the battery fluid
Normal tap water contains minerals which are harmful
to a battery; therefore, refill only with “distilled water”.
A poorly maintained battery will corrode and discharge
quickly. The battery fluid should be checked at least once a
month.
The level should be between the minimum and maximum
marks. Use only “distilled water” if refilling is necessary.
