ABSTRACT:
A system for depassivating a passivated lithium battery in a battery powered microprocessor controlled device by successively and momentarily drawing current from the passivated battery after a turn on of the device while monitoring the power delivery condition of the battery under a load condition until salt crystals on an electrode of the battery are dissipated and the battery is returned to a useful power delivery condition or until a predetermined period of time has elapsed without the battery returning to the useful power delivery condition, whichever is sooner.
