BATTERIE MIT INTEGRIERTER PRÜFUNGSVORRICHTUNG

摘要

The present invention relates to an electrochemical cell 10 and an integrally related state of charge indicator 12. The state of charge indicator has two electrical contacts and a display connected therebetween. A first contact 16 is connected to a first cell terminal and a second contact 14 is unconnected to either terminal. A switch 18, 19 permits electrical connection of the second contact to the second terminal to visually indicate the condition of the battery by the display means.
