Abstract
A battery is rendered to a consistent discharged state in a two-phase battery discharge operation. In a first of the two discharge phases, a constant discharge current is drawn from the battery until a threshold battery voltage is reached. In the second of the two discharge phases, executed after the threshold battery voltage is reached during the first-phase, a time-varying discharge current is drawn from the battery at a constant battery voltage until a threshold discharge current is reached.
