6 TC51 Touch Computer
Charging the TC51
1. To charge the main battery, connect the charging accessory to the appropriate power source.
2. Insert the TC51 into a cradle or attach to a cable. The TC51 turns on and begins charging. The Charging/Notification LED blinks
amber while charging, then turns solid green when fully charged.
The 4,300 mAh (typical) / 4,050 mAh (minimum) battery charges from fully depleted to 90% in approximately 2.5 hours and from
fully depleted to 100% in approximately three hours. 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 charging results use only Zebra charging accessories
and batteries. Charge batteries at room temperature with the TC51 in sleep mode.
Charging the Spare Battery
1. Insert a spare battery into the spare battery slot.
2. Ensure the battery is seated properly.
The Spare Battery Charging LED blinks indicating charging. See Table 2 for charging indicators.
The 4,300 mAh (typical) / 4,050 mAh (minimum) battery charges from fully depleted to 90% in approximately 2.3 hours and from
fully depleted to 100% in approximately three hours. 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 charging results use only Zebra charging accessories
and batteries.
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.
NOTE Ensure that you follow the guidelines for battery safety described in the TC51 User Guide.
