Charge batteries in temperatures from 5°C to 40°C (41°F to 104°F). The device or cradle always charges the battery in a safe and intelligent manner. At higher temperatures (e.g. approximately +37°C (+98°F)), the device or cradle may, for small periods of time, alternately enable and disable battery charging to keep the battery at acceptable temperatures. The device and cradle indicate when charging is disabled due to abnormal temperatures via its LED.
