Effect of Temperature
The Alkaline Manganese Dioxide system is best suited for use over
a temperature range of -4°F to 130°F (-20°C to 54°C).
At lighter loads, some output can be obtained at temperatures as low
as -20°F(-30°C). Actual service depends on cell size and
current drain. For most cells, up to 75 percent of the rated capacity
at room temperature can be delivered at 32°F(0°C).
The following figures illustrate how cell size and current drain affect
performance over a range of temperatures and low temperature performance
of alkaline and regular zinc-carbon cells. The alkaline cell will
maintain a higher voltage for considerably longer than the regular
zinc-carbon cell, resulting in a service life at lower temperatures
which is up to ten times that of the regular zinc-carbon cell.
