Abstract
A battery cell characterized by a plurality of cell plates housed in a container that includes a window adjacent to the edges of several plates. A triangular member of resilient material is attached at its base to the edge of at least one of the plates. The sides of the member contain two lands and the tip of the member contacts the window. The interface between the tip and the window is visible through the window as a single line. As the plate increases in size, the edges of the lands contact the window producing additional lines; the number of lines representing the gradual diminution in the cell life.
