A lithium cell which includes an outer conductive housing, a cathode having one major surface in contact with the conductive housing, an insulative separator adjacent to the other major surface of the cathode, and a lithium anode having a pair of major surfaces one of which is adjacent to the insulative separator. A resistive sensing element is disposed within the lithium anode and extends generally in a direction from one of the major surfaces of the lithium anode to the other major surface of the anode. An electrical conductor is connected to the resistive sensing element and extends out of the conductive housing so that as the lithium anode is consumed by the discharge of the cell the electrical resistance as measured between the conductive housing and the electrical conductor provides an indication of the level of discharge of the cell.
