A battery charge indicator is disclosed which is permanently incorporated into a battery to indicate the state of charge. The indicator includes a compressible chamber such as a blister (91) which is adapted to be installed in a battery (90) as an assembly. The blister chamber is filled with a viscous gel and is exposed to the expandable cathode of the battery. As the battery discharges, the cathode expands thus causing the gel within the chamber to be extruded out through an outlet into a viewing channel in an overlaying disk (95). The amount of expansion of the cathode thus indicates the amount of discharge and, conversely, the remaining life of the battery. A battery charge indicator is also disclosed in which the expansion of the cathode is adapted to apply localized pressure to a disk. The localized pressure applied to the disk causes stretching of the material of the disk, which causes a visual indication of the state of charge of the battery. |
