A State-of-Charge Test for Zinc-Mercuric Oxide Primary Cells.

Abstract

A readily instrumented and conducted nondestructive technique to determine the state of charge of zinc-mercuric oxide primary cells has been developed and preliminary results obtained. Measurements of the current vs voltage (1-V) characteristics, the AC impedance, the electronically sampled derivative at different sampling currents and frequencies, and the discharge-time characteristics of the cells as a function of charge expended have been made and are reported. The nearly constant slopes of the 1-V curves above 75 mA were measured graphically. These studies indicate that this technique constitutes a useful, easily applied state-of-charge test.
