Operating mode of three-step charger
Constant current mode: When the voltage of the battery is lower than the value set by the charger, the
charger will work under the constant current mode and supply the constant 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 charged fully and avoid over charged.
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 the 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.
