ABSTRACT:
The invention relates to a process for determining the starting capacity of a starter battery of a motor vehicle for which the mean value for the voltage surge during the starting of an internal combustion engine, is determined as a function of mean values for the battery and engine temperatures, compared with the voltage surge values of a characteristic line field which records determined voltage surges as a function of corresponding battery and engine temperatures, a deviation of the actually determined voltage surge from the voltage surge stored in the characteristic line field is determined and compared to a preassigned value, and an indicator or an alarm is triggered as soon as the preassigned value is exceeded.
