Abstract
The Canadian armed forces use large quantities of alkaline cells, often in cold field conditions. In recent years the manufactures of alkaline cells have been gradually lowering the mercury content of these cells, primarily because of the environmental hazards of mercury. The present study was undertaken because of the concern that the removal of mercury might adversely affect performance, especially in the cold, and also diminish the resistance to mechanical shock and vibration, and shelf life. This investigation of some of the performance characteristics of alkaline cells was conducted in comparison with older cells which contained higher levels of mercury. It was found that the room temperature performance of alkaline cells was execllent. However, between 5C and -20C, low-mercury cells manufactured since 1992 had performance that was inferior to the older cells.
