8.4 Temperature Effects on Batteries
C&D recommends that the batter y be operated at 77°F (25°C) ± 10°F (5. 5° C). For am bie nt tempe rat ure s
out side t he rec omm ended t emp eratur e ra nge, th e float volt age mu st be adj uste d by 2mV pe r °F or 3.6mV
per °C. Adjust as indicated below.
Add 2m V (0. 002 vo lts) pe r °F or 3. 6mV per °C belo w 77° F (25°C ). Subtr ac t 2m V ( 0.00 2 volts) p er °F or
3.6mV per °C above 77°F ( 25°C).
If th e bat t er y i s o per at ed a t t em p er atu re s be l ow t h e r ec omme n ded r ange, the capacity will be reduced
even with temperature compensated charging, which must be accounted for during initial system sizing.
