LowerTemperatureConditions:
Air holds les s moisture as temperature decreases, and the diffe rence between low and high relative
humiditybecomeslesssignificant.At0°C,thedifferencebetweenthehumidityofthePP355andthe
environment is negligible.While the service obtained from a PP355 at temperatures lower than
standard conditionsis less, the
lossis similar to Alkalinebatteries.In general the “up to 3X” service
advantageforZincAirbatteriesoverAlkalinebatteriesismaintained.
