ABSTRACT:
A battery is provided with an end-of-cell voltage indicating device which can be used to indicate the state-of-charge of the battery. The indicating device has a flexible substrate of the same peripheral configuration as the battery. The substrate has an indicating coating on one surface which is in thermal or electrical contact with a conductive circuit pattern which can be temporarily connected between the terminals of the battery on application of pressure to an indicated spot on the surface of the substrate. The conductive circuit means causes the indicating coating to undergo a visible change which is representative of the state-of-charge or voltage of the battery. A dual end-switched, integral battery and state-of-charge indicating device having two switches disposed on one end of the battery is also disclosed.
