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.

Battery charging system

An electrical battery is provided which includes a current sensing resistor situated in series with a plurality of battery cells located within a housing. The respective ends of the plurality of cells are coupled to positive and negative contacts on an external surface of the battery. The respective ends of the current sensing resistor are coupled to first and second sensing contacts on the external surface of the battery. A battery structure is thus provided which is capable of supplying electrical energy while permitting sensing of the magnitude of electrical current drawn from the battery.
