Abstract
In one preferred embodiment of the invention, a method of restoring charge to a battery operating with a predetermined terminal voltage, including: determining an expected rate of degradation of a plate or plates of a battery in terms of decrease of capacity per unit time and temperature of operation of the battery to determine a degree of degradation of capacity of the battery; and providing sufficient charge to the battery to restore a predetermined degree of the capacity of the battery. In another preferred embodiment of the invention, a method of diagnosing state of health of a battery, including: restoring a theoretical amount of charge to a partially depleted battery; and examining how the battery responded to the step of restoring a theoretical amount of charge to the partially depleted battery to determine the state of health of the battery.
