Charging Temperature
Charge batteries in temperatures from 0°C to 40°C (32°F to 104°F). The battery charger always performs battery
charging in a safe and intelligent manner. At higher temperatures (e.g. approximately +37°C (+98°F)) the battery
charger may for small periods of time alternately enable and disable battery charging to keep the battery at
acceptable temperatures. The battery charger indicates when charging is disabled due to abnormal temperatures
via its LED.
