ABSTRACT:
A novel automotive battery life diagnosis apparatus is disclosed, in which the terminal voltage, charge-discharge current and the temperature of a battery are detected, output signals from the detectors are applied to and processed in a predetermined manner by a control unit, and a life alarm is displayed on a display unit. Further, the control unit has the functions to calculate a value representing the life of the battery from the detection signals of the detectors before and after cranking of an internal combustion engine and to store an initial value of a parameter representing the battery life in the initial stage of battery operation. The initial value of the parameter is compared with the present value thereof to forecast and indicate the life of the battery on the display unit from a predetermined relationship formed by life curves between the initial value and the present value of the parameter.
