ABSTRACT:
A battery voltage course is estimated during the actual discharge. The battery voltage is registered at a plurality of different times, and parameters for describing the battery discharge course are determined locally for said times in response to the registered values and the associated times. The registered service life is determined on the basis of the battery discharge course, and the remaining service life may e.g. be the remaining standby time of a radio telephone.
