Charge and discharge of Li-Battery
If users apply the Li-Battery on GT-530, the Li-battery would be charged by the
external power automatically. When the external power is removed from GT-530, the
power supplying to GT-530 is from Li-Battery. If the voltage of Li-Battery is lower than
the preset limit, GT-530 can send the SMS message to inform the users.
Note: A new Li-Battery can supply power to GT-530 for 36 hours without the
external power. The power volume of Li-Battery would be decreasing for a
long time. It is recommended to change the Li-Battery every 6 months.
