Abstract

An electrochemical cell is provided with an integrally related state of charge indicator comprising an electrochemically generated display. The state of charge indicator comprises two electrical contacts and an electrochemically generated display connected therebetween. The display comprises an electrochemical cell that is permanently connected to the cell in a parallel configuration via the contacts. The condition of the cell is thus continuously displayed.
