A portable telephone is connected as the load 6, and the switch 5 disconnects the connection between the primary battery 2 and the secondary battery 3 during a call. Power is supplied to the load 6 from 3. When the mobile phone 6 is not used, the switch 5 connects the primary battery 2 and the secondary battery 3 and the primary battery 2 charges the secondary battery 3.
