A combination battery includes a plurality of cells connected together in series. A switching element operates for selectively blocking and unblocking a power feed path between the combination battery and a load. The switching element is changed to its on state when receiving a drive voltage. When a starting switch is moved to its on position, a drive circuit is connected with at least one cell among the cells in the combination battery and uses the at least one cell as a power source to generate the drive voltage applied to the switching element. A power supply circuit receives an output voltage from the combination battery and starts to operate when the switching element is changed to its on state. At a later moment, a power source for setting the switching element in its on state is changed from the at least one cell to the power supply circuit.
