DEFINITION OF COMMON TERMS
Buss Bar - A means of attaching one charger to two or more batteries to be charged at the same time.
Passivation - When batteries are left in a discharged state, a layer of lead oxide begins to coat the plates hampering
the cells' ability to accept or release energy. Passivation may result in a battery taking 24 hours or more to begin to
draw current during charging, and may result in false "bad battery" readings by battery analyzers and chargers.
Pulsing - Some chargers apply "pulses" of current to the battery, purported to remove the sulfating layers
accumulated on the battery cell plates.
Vent - There are six vents per 12 volt battery. They are located in the lid in a 3X2 pattern, circular in shape, one inch
or 2.5 cm in diameter.
