Abstract

PURPOSE: To make it possible to directly and reliably know the capacity of a battery by detecting the bettery voltage of a secondary battery, which has its voltage is proportional to the capacity, so that the battery voltage is acoustically displayed.
CONSTITUTION: The terminal voltage of a secondary voltage such as a lithium battery, the voltage of which is used to drive a watch and is proportional to the capacity, is judged by judging circuits 4a and 4b, in which different standard voltages are set by voltage dividing resistors 4a' and 4a", and 4'b and 4"b, so that the circuits 4a and 4b generate judging signals of high and low levels in accordance with the battery voltage. In accordance with the judging signals, the conductions of the gates 4f to 4h are controlled through gates 4c to 4e so that the signals having such a frequency as is different in accordance with the battery voltage proportional to the battery capacity are applied from a watch circuit 6a through an OR circuit 4i to a speaker 7a. As a result, the battery capacity is directly displayed in an acoustic manner so that the control of the charging circuit connected with a battery 3a can be properly controlled.
