Abstract
There is described a method of diagnosing a motor vehicle battery, wherein, at each start-up of the vehicle engine, a number of parameters, related to the pattern of an electric quantity supplied by the battery during a transient start-up state of the engine, are recorded; and the recorded parameters are then memorized to create a database which is used to determine the charge status of the battery.
