Low Voltage Activation Function
When the charger is standby, if the low voltage battery (battery voltage ≤ 2.9V),correctly access to the charging channel, the charger trickle charge function will start, automatically activate the low voltage battery. Due to low-voltage battery over discharge times, capacity, over-discharge degree, the duration of low voltage and other factors, the activation time is very different. After the battery is activated, follow the charging process to charge.

Overcharge Protection and Automatic Detection of Charging Function
When the battery is full, the charger starts overcharge protection and automatically stops charging. If not remove the battery for a long time after full charging, the charger will consume a certain amount of battery power. When the battery voltage is lower than 4.0V, the charger restarts the charging function.
