Precautions for Using the Battery
Certain files and information may be stored in the memory. If the battery
runs out, these files and information are lost. Therefore, providing power
to the device constantly is very important.
In general cases, the device can work for more than eight hours after it is
fully charged. When the electricity is reduced to a certain level, the system
indicator blinks and a warning indicating electricity insufficiency is
displayed. If you continue to use the device, the device switches to sleep
mode or is turned off automatically.
To extend the battery life, you must follow the following advices:
1.
Minimize the battery charge and discharge times and charge the
battery only when the system displays the electricity insufficiency
warning.
2.
Prevent over discharge in daily use and charge the battery
immediately when the system displays the electricity insufficiency
warning. Over discharge shortens the battery life.
3.
Prevent overcharging in daily use and stop charging when the
battery electricity exceeds 95%. You must calculate the charging
time correctly when a seat charger is used. Do not charge a
fully-charged battery because over charging shortens the battery life.
4.
Charge and discharge the battery completely when you use the
battery for the first time and every three months.
5.
If the battery is not used for a long time, you must remove the
battery from the device and retain 50% of electricity in the battery.
