Abstract
Described is a battery de-passivation circuit that generally comprises a battery having a de-passivation circuit attached across its positive and negative terminals. The de-passivation circuit includes a switch that can open or close the de-passivation circuit, a resistor that can regulate the amount of current drawn from the battery and a clock and timer controller system that controls the switch. The controller system controls closing the circuit long enough to bring the passivation level build-up within the battery to an acceptable lower level and controls opening the circuit long enough to allow passivation levels to build-up to an acceptable upper level.
