PROBLEM TO BE SOLVED: To provide a battery pack in which an appropriate number of unit cells are connected corresponding to the dark current and output of the loads to be connected. SOLUTION: The battery pack is composed of a plurality of unit cells 10a, 10b connected in series and a plurality of loads 2A, 2B connected. The unit cell group which constitutes the battery pack is constructed of a first unit cell group 10a in which the capacity of the unit cell is relatively large and a second unit cell group 10b in which the capacity of the unit cell is relatively small. Out of the plurality of loads, the load 2B having a relatively large dark current is connected to the first unit cell group 10a. COPYRIGHT: (C)2008,JPO&INPIT
