Abstract
A battery charging unit communicates with an operational device while contemporaneously charging a battery to power the device. The device provides information to the charging unit indicating its present operational status, which enables the charging unit to determine the magnitude of the proper charging current under such operating conditions. In this way, battery life is maximized while battery charging time is minimized.
