3. Additional Functions
The following additional functions can be used to protect and extend the battery life:
 Storage Self-Discharge
If the battery is stored in a high-temperature environment or has not been used for
6 days, but the battery power is still high, the self-discharge protection mechanism
will be activated. The battery will automatically discharge to a safe level. This is a
default setting, and the discharge takes about 2-3 days. Although there is no
prompt message indicating that the battery is self-discharging, you may notice that
the battery feels slightly hot. This is normal. You can customize the battery
discharge threshold using the Autel Explorer App.
