Auto Four- Phase Charging Mode Car Battery Charger (MA-1240A)

Three-phase charging mode

Constant current mode: When the battery voltage is lower than the value set by the charger, the charger will operate in constant current mode and provide constant current to the battery.

Constant voltage mode: Using pulse width modulation (PWM) technology to control the charging current and output voltage of the charger, which ensures the battery is fully charged and prevents overcharging.

Floating charge mode: when the battery voltage approaches the constant voltage mode value and the current gradually decreases to the set current, it means that the battery is full, the indicator lamp will turn green and the fan will stop working. The charger will automatically switch the mode to float charging mode. At this point, the battery can be stopped charging or left on float charge for half an hour.
