Charging Temperature
Charge batteries in temperatures from 0 °C to 40 °C (32 °F to 104 °F). The device or cradle always
performs battery charging 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 indicates when charging is
disabled due to abnormal temperatures via its LED.
