1.7 Charging
The main battery may not be charged to full for shipment. When you first receive the kit package, you
need to charge the main battery to full before using BHT. You may use the Communication Unit or
multiple BHT charger to charge the BHT.
1.7.1 Charging time
The main battery powers the BHT to work. It takes approximately 3 hours for BT-110LA standard
battery and 4.5 hours for BT-110L large capacity battery to charge an empty main battery to full. The
status indicator above the screen (located on the right) will light up in red while charging and will turn
green when charging is complete.
The backup battery is mounted on the main board. Its role is to retain data in DRAM when the main
battery is replaced. Replace the main battery within one minute. To charge a backup battery to full, it
takes approximately 10 hours from the completely discharged state to the fully charged state using the
main battery or power adapter.
1.7.2 Charging temperature
It is recommended to charge the battery at room temperature (18 ° to 25 ° C) for optimal performance.
Note that battery charging stops when the ambient temperature drops below 0 ° C or exceeds 40 ° C.
1.7.3 Operation on battery power
When 802.11a/b/g/n, GSM/GPRS/EDGE/WCDMA/UMTS/HSDPA/HSUPA/HSPA+/LTE, Bluetooth
v4.1+EDR/LE and GPS are all enabled on battery power, the main battery level will drop down
substantially. Prolonged use of the display and continued scanning of barcodes will also affect battery
level.
In order to prevent system from shutting down after the battery is drained out, we suggest that you
keep a fresh battery for replacement at all times, or connect BHT to the Communication Unit or USB
Direct Cable for charging.
