BU-410: Charging at High and Low Temperatures
The charging process is more delicate than discharging and special care must be taken. Extreme cold and high heat reduce charge acceptance and the battery should be brought to a moderate temperature before charging. Older battery technologies, such as lead acid and NiCd, have higher charging tolerances than newer systems, such as Li-ion.
