Abstract
A voltage and internal resistance of a battery are measured in advance as its capacity decreases. In a flash memory of a device powered by the battery, voltages necessary to drive a motor, an EL display, and a bezel input unit are stored. By comparing the voltage of the battery with a resistor connected as a dummy load and the voltage read from the flash memory, it can be determined whether it is possible to drive the motor, the EL display, or the bezel input unit.
