ABSTRACT:
An appliance, such as a flashlight, accepts first and second batteries. The appliance also includes an electrical load, such as a light source. A first circuit, such as a DC to DC converter, receives power from the first battery and supplies power to the load. A second circuit, such as a DC to DC converter, receives power from the second battery and supplies electrical power to the load. In one embodiment, the appliance accepts batteries having multiple physical sizes.
