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-ONTOY batteries, suit for type of batteries included AGM FEL VRLA SLAWET and deep-cycle.

4-Stage charging process
Stage 1, initialization, when the charger powers on then it starts self-check and detect the battery correct connects. 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 (LED 50% ON, 100% blinking)
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.

WARNING
1.This charger is designed for charging AGM,GEL,FLOODED(Wet), Calium type deep cycle, VRLA maintenance free lead acid batteries from 5 to 40Ah, Do not use for any other purpose.
2.Since batteries may emit explosive gases, always provide good ventilation and avoid any source of flames or sparks when charging.
3.To reduce risk of damage to electric plug and cord, pull by the plug rather than by the cord when disconnecting charger.
4.Use of an improper extension cord could result in a risk of fire and electric shock.
5.Do not operate charger if you notice any signs of damage to charger or cords.
