Abstract
The invention relates to a two-celled battery for use in cardiac pacer devices which comprises an outer encasement member and first and second internal cell elements. Each of the first and second cell elements includes an insulating cup, a lithium anode positioned within the cup, and a cathode positioned in contact with said anode. Each of the insulating cups includes an opening therethrough such that the lithium anode in the first cell makes contact with a terminal mounted through and insulated from the encasing means and the anode of the second cell is electrically in contact with the cathode of the first cell. The insulating cup of the second cell is positioned within the insulating cup of the first cell and both first and second cells are positioned within the encasing means such that the terminal contact with the first lithium anode and the encasing means is in contact with the cathode of the second cell.
