Abstract
A method of determining the starting ability of a starter battery of an internal combustion engine, according to which a charge status of the starter battery is determined, which has an influence on starting ability. Also determined is a temperature which has an influence on starting ability, in particular the temperature of the starter battery. Moreover, an average voltage drop of the starter battery during a starting phase is calculated or determined, in particular during a turn-over phase of a starter motor, which is in an operative connection with the starter battery. The starting ability of the starter battery is estimated by comparing the calculated or determined average voltage drop with a threshold value.
