A cardiac pacer having an alkali metal-halogen cell comprising an alkali metal anode, preferably lithium, a solid alkali metal-halogen electrolyte and a cathode comprising a mixture of two halogens, for example iodine and bromine, the two halogens providing discharge of the cell at two different levels of cell output voltage. The two halogens are in different proportions by weight of the mixture thereby providing a two step output voltage-time characteristic. The second step or plateau in the output voltage characteristic provides an early warning of pacer battery exhaustion. |
