8.4 Temperature Effects on Batteries
C&D recommends that the battery be operated at 77°F (25°C) ± 10°F (5.5°C). For ambient temperatures
outside the recommended temperature range, the float voltage must be adjusted by 2mV per °F or 3.6mV per
°C. Adjust as indicated below.
Add 2mV (0.002 volts) per °F or 3.6mV per °C below 77°F (25°C). Subtract 2mV (0.002 volts) per °F or 3.6mV
per °C above 77°F (25°C).
If the battery is operated at temperatures below the recommended range, the capacity will be reduced even
with temperature compensated charging, which must be accounted for during initial system sizing.
