Abstract

PURPOSE: To detect surely the life of a battery with a simple constitution by counting the usable time of the battery, which is obtained from the current consumption of an apparatus, with pulses.
CONSTITUTION: When new battery 11 is inserted to electronic apparatus 12, oscillation circuit 14 oscillates, and the output is inputted to input terminal 16a of N- notation counter 16. This counter 16 counts the number of pulses of the inputted signal, and an output is generated from output terminal 16b when the count value becomes n. By this output, report circuit 17 is operated to output a signal. As the result, speaker 18 isseus a report tone to report that the life of battery 11 ends.
