Backup Power
The device is equipped with a supercapcitator (supercap) to provide backup power to the device when the
main battery is removed. The supercap will retain random access memory (RAM) data in memory for
approximately five minutes after the main battery is removed during Hot Swap.
IMPORTANT: The supercap is automatically charged from the main battery and requires approximately
ten minutes to fully charge.
Charging Temperature
Charge batteries in ambient temperatures from 0°C to 40°C (32°F to 104°F) or up to 45°C (113°F) as reported
by the battery. To view battery temperature, go to Settings > System > About phone > Battery information.
The device or cradle always performs battery charging in a safe and intelligent manner. At higher temperatures
(for example, 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.
