A Battery for Arctic Radio Repeater Systems.

The effect of temperature on the working voltage of air depolarized cells (Model 608z, 2000 Ah) at various stages of discharge has been investigated. Discharge currents of 0.2 to 1.0 A at temperatures from 20 C to -55 C were examined as were the effects of increasing the electrolyte concentration fr...

Description
Summary:The effect of temperature on the working voltage of air depolarized cells (Model 608z, 2000 Ah) at various stages of discharge has been investigated. Discharge currents of 0.2 to 1.0 A at temperatures from 20 C to -55 C were examined as were the effects of increasing the electrolyte concentration from 22% to 27% and 29% KOH. The results confirm that air depolarized cells can form a suitable power source for an unattended 30 W radio repeater station in the arctic if the cells are connected in a series/parallel arrangement such that the current drain from each cell does not greatly exceed 0.2 A.
