A battery unit including a battery ( 3 ) is equipped with a monitoring circuit ( 9 ) for detecting and evaluating operating variables related to charge state of the battery ( 3 ). So that energy is not drawn from the battery ( 3 ) by its own monitoring circuit ( 9 ) when an external load ( 2 ) powered by the battery unit is shut off, the supply of electrical power to the monitoring circuit ( 9 ) in the battery unit is disconnected, either immediately or after a certain time delay, when the load ( 2 ) is shut off. This slows the discharge of the battery ( 3 ) when it is not supplying electrical to the load ( 2 ).
