Abstract
A battery is charged using a heavy charging phase, followed by a pulse charging phase. During the latter, charging continues beyond a predetermined battery voltage, for a predetermined interval. During a measuring portion of the succeeding charging pause, the falling battery rest potential is measured and the pulse charging phase is terminated when the measured rest potential no longer falls below a predetermined level.
