Equalizing Batteries
Lead plates become sulfated as a natural result of their function; breaking this deposit loose and keeping the plates
"clean" will equalize each cell's ability to do its work.
Equalizing is an overcharge performed on fl ooded/wet batteries after they have been fully charged. This action "scrubs"
the plates, and the sulfates will fall to the bottom cavity of the battery. Trojan recommends equalizing only when batteries
have low specifi c gravity, (below 1.250), or wide-ranging specifi c gravity, (0.030) after fully charging a battery. This could be
as much as once per month during busy times. Keeping the plates active and "equal" will extend battery life.
• Check electrolyte level to make sure all plates are covered with water before charging
• Check that all vent caps are secured properly on the battery before charging
• Set the charger to equalizing mode (The J&J Master Charger has this function)
• The batteries will gas (bubble) during the equalization process.
<WARNING>
MAKE SURE BATTERY COMPARTMENT IS WELL VENTILATED, AND REMEMBER THE GASSES GIVEN OFF ARE HIGHLY
EXPLOSIVE!
• Measure the specifi c gravity
(See page 5-149).
CLEANING
Warm water and soap works well to neutralize acidic or corrosive conditions. Rinse with clean water after washing.
In some cases, almost all the batteries in the pack may test "good" and only one may show poor specifi c gravity or a low
cell. Many times, a battery in this condition can be recovered by removing it from the pack and putting it on a separate
6- volt charger that has a boost or equalize feature. (See page 5-153)
