water to cover the plates. Then, after
charging is completed, add enough water to
bring the electrolyte up to the indicator mark.
If the water level is topped off before
charging, normal expansion of the
electrolyte may cause an overflow, resulting
in loss of acid balance and acid damage to
the machine area around the batteries.

wall outlet. the charger will go through a self
