Abstract: A simple battery and battery charger. In one embodiment, the battery charger includes an output terminal that provides a charging voltage Vout and charging current Iout. The battery is contained in a battery pack having an input terminal, which can be connected to the output terminal in order to receive Vout and Iout. The battery charger may include a first circuit for controlling the magnitude of Vout. The battery pack may include a second circuit that generates a control signal when the output terminal is connected to the input terminal. The first circuit is configured to control the magnitude of Vout based on the control signal.
