Battery Charging
Main Battery Charging
The device’s Charging/Notification LED indicates the status of the battery charging in the device. See Table 3
on page 21 for device charging status. The battery charges from fully depleted to 90% in approximately 2.5
hours and from fully depleted to 100% in approximately three hours.
NOTE: In many cases the 90% charge provides plenty of charge for daily use. A full 100% charge lasts for approximately
14 hours of use.
To achieve the best fast charging results use only Zebra charging accessories and batteries. Charge batteries at room
temperature with the device in sleep mode.
Charging Temperature
Charge batteries in temperatures from 5°C to 40°C (41°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.
