Abstract

PURPOSE:To report the life of a battery simply and positively, by generating the alarm sound by an alarm setting switch and a battery life detecting circuit. CONSTITUTION:After the voltage of the battery has decreased and the output of the detecting circuit V has inverted, the alarm switch S1 is closed and the alarm is set. Then the output of a flip flop circuit F becomes a high level and the alarm sound is generated by an alarm sound generating circuit P. Thus the battery life can be reported by the sound simply and positively.
