Abstract
A battery controller for controlling at least two batteries of different kinds, includes a kind-of-battery detection unit for detecting a kind of battery, and a battery switching unit in which a switching voltage, a suspended mode shift voltage and a termination voltage having different values in accordance with the kind of the battery detected by the kind-of-battery detector are previously set to compare an output voltage of a battery being discharged with the previously set switching voltage, suspended mode shift voltage and termination voltage so that switching of the battery being discharged, stopping of operation of an apparatus being supplied with electric power by the battery being discharged or stopping of supply of electric power by the battery being discharged is performed.
