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 26 for device charging status. The standard battery charges from fully depleted to 90% in
approximately three hours. The extended battery charges from fully depleted to 90% in approximately four
hours.
NOTE: In many cases the 90% charge provides plenty of charge for daily use.
To achieve the best fast charging results use only Zebra charging accessories and batteries. Charge
batteries at room temperature.
Spare Battery Charging
The Spare Battery Charging LEDs on the 4-Slot Battery Charger indicate the status of the spare battery
charging. The standard battery charges from fully depleted to 90% in approximately three hours. The
extended battery charges from fully depleted to 90% in approximately four hours.
NOTE: In many cases the 90% charge provides plenty of charge for daily use.
To achieve the best fast charging results use only Zebra charging accessories and batteries.
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 (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.
