Abstract
A rechargeable battery having a switch connects an internal load to the battery so that the battery can be shifted to a predetermined, lower load state. To shift the rechargeable battery into a lower load state for long-term storage, a Zener diode is connected in series with a resistor and the switch. The rechargeable battery voltage, which corresponds to the predetermined, lower load state, is selected as the breakdown voltage of the Zener diode. Manual actuation of the switch shifts the rechargeable battery to a lower load state, if the current load state is higher than the predetermined, lower load state. A digital version has a digital circuit connected electrically to the switch which is arranged for measuring the rechargeable battery voltage and which in the ON state triggers the switch if the measured rechargeable voltage exceeds a value that corresponds to the predetermined, lower load state.
