Charge batteries in temperatures from 5°C to 50°C (41°F to 122°F). The device or accessory always performs battery charging in a safe and intelligent manner. At higher temperatures, for example, at approximately 37°C (98°F), the device or accessory may for brief periods of time alternately enable and disable battery charging to keep the battery at acceptable temperatures. The device or accessory indicates when charging is disabled due to abnormal temperatures via its LED and a notification appears on the display.
