ABSTRACT:
Apparatus and methods for recharging various types of battery cells are enclosed involving alternating periods of charging and discharging of the cells, a reference charge cut-off voltage, a comparator for comparing cell voltage with cut-off voltage, and a circuit for stopping charging activity when cell open circuit voltage is at least a desired minimum voltage. Charge activity is terminated following the achievement of a minimum acceptable state-of-charge so as to limit the total current delivered to the cell in order to prevent cell degradation.
