Abstract

A method and apparatus for monitoring the state or condition of charge of a battery which supplies a plurality of electrical consumption devices in an electronic circuit. A consumption device is operatively connected to a series of counters so that the count condition charges in response to a pulsing rhythmic cycle by one of a plurality of numerical values toward a final count condition, in which the numerical values are specific in relation to the power consumptions of a plurality of electrical consumption devices, and that a signal is generated upon the reaching of a final count condition.
