ABSTRACT:
The invention is directed to an electrical device in which an electrical load is powered by a battery via an electronic switching device. A display means serves the function of indicating the charge status of the battery, and a time measurement means determines the connection time of the load to the battery. Following expiration of a predetermined connection time of the load to the battery, when the display means indicates the charge status "zero", the time measurement means will disconnect the electrical load from the battery by means of the electronic switching device.
