An apparatus for diagnosing the residual charge of a battery mounted in a vehicle which utilizes an engine includes a comparator for comparing the terminal voltage of the battery with a reference voltage, a stoppage detecting circuit for detecting that the operation of the engine has stopped, a timer for determining that a predetermined time has elapsed since the stoppage detecting circuit detected that the operation of the engine stopped, and a determination circuit for determining the residual charge of the battery from the comparison result provided by the comparator when the timer determined that the predetermined time has elapsed. |
