Four-Phase Charging Mode:
Pre-charge mode: In order to protect the battery and extend its life, the battery’s internal resistance is too large 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 the voltage of the battery rises to the given voltage value, the charge mode will turn to constant current charge mode automatically.
Constant current mode: The charger supply constant charge current for the battery.
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 fully charged and avoids overcharging.
Floating charge mode: When the voltage of the battery is approaching 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 the pilot lamp will turn green and the fan will stop working. The charger will turn the mode into a floating charge mode automatically. At this moment, the battery can be stopped charging or keep on floating charge for half an hour.
