The initial effort to analyze the present factory product E-95 D size Alkaline-MnO2 round cell with special emphasis placed on location of problem areas affecting low temperature, heavy drain service. Empirical data was obtained from variations of electrode and electrolyte formulations as well as separator materials. An optimized cell was obtained for use in factory trials. This cell contains a cathode with a 41 ore to carbon ratio, an electrolyte with 40 KOH as dispensed into the cell approximately 32 equilibrium value in the anolyte, a ViskonVinyon separator and a powdered zinc anode. The work to date has indicated a need for a higher surface area zinc. Uniformity of cathode mix formulations will also be characterized with respect to solution volumes, packing, density, etc.
