8.3 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 compensated for during initial system
sizing.
NOTE:
Chargers should be current limited to 25 amperes per 100-Ampere Hour battery rating.
Higher charging current could potentially destroy the battery by overheating that
subsequently causes more current to flow creating a vicious cycle sometimes referred
to as “thermal runaway”.
NOTE:
Use the equalize voltage setting shown in Table 1 for a period not exceeding 16 hours.
