6. Operating Instructions
Once the charger is properly connected and plugged into a power source, you can begin the charging process.
Charging Process:
- Turn on the charger's On/Off switch. The LED indicator will illuminate to show the charging status.
- Monitor the LED indicator for real-time status updates.
- Once the battery is fully charged, turn off the switch and disconnect the charger.

LED Indicator Status:
- LED Flashes Green: Charger is on standby.
- LED Always on Red: Battery is charging.
- LED Always on Green: Battery is fully charged.
- LED Flashes Red: Charger fault or under protection.

Smart 3-Stage Charging Modes:
The charger automatically adjusts its output based on the battery's state of charge.
- Pre-Charge Stage (T1): For deeply discharged batteries, the charger sends a gentle, limited current to safely raise the voltage and activate the battery.
- Constant Current Charging Stage (T2): Once the battery is active, the charger delivers full 40A current until the battery voltage reaches the set value.
- Constant Voltage Charging Stage (T3): The charger switches to constant voltage, gradually decreasing current as the battery approaches full charge. Charging stops when the battery is fully charged.
