At freezing battery capacity is about 20% lower, at 122 degrees F battery capacity is around 12% higher. The charging voltage for a battery will also vary from 2.74 volts per cell (16.4 for a 12v battery) at -40c to 2.3 volts per cell (13.8 on a 12 volt battery) at 50c. Some charge controllers have this temperature correction built in.
How to Charge NiMH Batteries: 12 Steps (with Pictures)
NiMH (nickel-metal hydride) and NiCad (nickel-cadmium) batteries are two of the most challenging batteries to charge properly and safely. These nickel-based batteries do not allow you to set a maximum charge voltage, so overcharging can result if you are unaware of the proper charging methods for nickel batteries.
