Overcharging will dry out the electrolyte and damage battery. Equalizing is an overcharge performed on flooded lead-acid batteries after they have been fully charged. It reverses the buildup of negative chemical effects like stratification, a condition where acid concentration is greater at the bottom of the battery than at the top. Equalizing also helps to remove sulfate crystals that might have built up on the plates. If left unchecked, this condition, called sulfation, will reduce the overall capacity of the battery.
Many experts recommend that batteries be equalized periodically.
Ranging anywhere from once a month to once or twice per year. Remove all loads from the batteries. Connect battery charger. Back to Top Discharging Discharging batteries is entirely a function of your particular application. Equivalent to overheating a car s engine, extent of damage unknown.
