Charging and maintenance of internal battery
X5105 has a built-in 5000mAh battery pack. When the external power supply is not
connected, the battery pack supplies power to the X5105, when the X5105 is connected
with an external power supply, the circuit inside the machine automatically switches to
the external power supply.
Charging method:
1In the menu, select [CHG] option, start charging function.
2The external power supply voltage is set between 13.5V-14.0V and the power supply
is connected to the X5105 external power supply.
The host will automatically start charging.
3Charging time is 10 hours. By then, the charge will automatically stop.
When the battery is powered for X5105, when the battery power is about to run out, the
power indication sign on the upper right corner of the screen is displayed as . At this
point, the X5105 should be charged or switched to an external power supply. During the
charging process, the casing of the machine has a slight fever.
Normally, the lifetime of the internal battery is about 4-5 years. Please replace the battery
when the battery has a noticeable capacity drop or charge fails.
When the X5105 is connected to an external power source, and when the X5105 is in the
transmitting state, it is strictly forbidden to disconnect the power supply so as not to
damage the power management chip.
Please turn off the power immediately when the machine shell is very hot near the
battery, and put the equipment in a safe and ventilated place. After confirming the
safety situation, please contact us for proper handling.
