Brief: This device is 4 stages smart battery charger by
Microprocessor controlled with switch mode for 6V and 12V is selectable output .it is ideal for charging your CAR,MOTORCYCLE AND RIDE-ON TOY batteries,suit for type of batteries included AGM GEL VRLA SLA WET and deep-cycle.
 4-stage charging process:
Stage 1:
initialization,when the charger power on then it start self-check and detect the battery correct connect. low output voltage without battery Fault LED is light, please CHECK THE POLARITY IS CORRECT.
Stage 2:
Bulk charge,using the charger highest rated current for the type of battery in use until it reaches 80% capacity( LEDs 50% blinking ,100% OFF)
Stage 3:
Absorption,the output voltage is limited to 7.3V(6V battery) or 14.5V(12V battery) while current declines as the battery charges to its full capacity without overheating( LEDs 50% ON ,100% blinking)
Stage 4:
Float,At this stage,the battery is fully charged and the charger maintains the battery through pulse charging( LEDs 50% ON ,100% ON)
 
IMPORTANT WARNING:
Before charging,make sure the correct battery voltage with the device voltage as same.
