Example A series of D-sized cells having standard steel jacket In Group No. l, the anode was a .025 inch sheet containing 3.5 percent aluminum, 0.24 percent calcium, 0.96 percent zinc, and 0.13 percent indium, the balance being magnesium. The cells from Group 2 containing a similar sheet anode alloyed from 3.1 percent aluminum, 0.17 percent calcium, 0.86 percent zinc, percent indium. These anodes were employed with an electrolyte consisting of 400 grams per liter of magnesium bromide, and 0.36 gram per liter of sodium chromate solution. The cathode mix was 87 percent manganese dioxide, 3 percent barium ch-romate, percent acetylene black and 0.25 percent magnesium powder. It was wet with 440 milliliters of electrolyte per thousand grams of dry material. The weight of the wet cathode mix was 54 grams per cell. These cells were hooked five in a series to make a nine volt pack. Each nine volt pack was employed in an RCA. Transistor Radio 7-B-l0K maintained at a predetermined volume of nine milliamperes and the delay measured by determining the time required to reach this volume. The series of cells were discharged 2 hours per day through 900 ohms to an end voltage of 6 volts. The delay average was determined over this period and the delay was measured at the beginning of the two hour discharge. This test resulted in the following results:
