Pre-charger mode

In order to protect the battery and extend its life, the battery’s internal resistance is too larger or voltage is too low because the discharged time is too long or it is not used for a long time, the charger will supply low output current for the battery automatically. When voltage of the battery rises to the given voltage value, the charger mode will turn to constant current charge mode automatically.

l  Constant current mode

The charger supply constant charger current for the battery.

l  Constant voltage mode

Using the pulse width modulation (PWM) tech to control the charging current and output voltage of the charger which ensure the battery is charged fully and avoid over charged.

l  Floating charge mode

When the voltage of the battery is closing the value of the constant voltage mode, and the current cut down to the given current gradually, that means the battery power is full, then pilot lamp will turn green and the fan will stop working. The charger will turn the mode into floating charge mode automatically. At this moment, the battery can be stopped charge or kept on floating charge.
