To shift a rechargeable battery into a lower load state that is ideal with regard to storage and aging, it is proposed that a Zener diode connected in series with a resistor and a switch. The rechargeable battery voltage, which corresponds to the predetermined, lower load state, is selected as the breakdown voltage of the Zener diode. On being started manually, the rechargeable battery is shifted to a lower load state, if the current load state is higher than the predetermined, lower load state. A digital version by means of a manually switched-on digital circuit is also proposed.
