6. Maintenance Charging: The charger can be left connected to the battery indefinitely to provide maintenance charging.

12V Battery Charging Steps:

1. Plug into household 220V power supply. 2. Select the corresponding mode. 3. Red clamp to positive pole, black clip to negative electrode. Start charging.

24V Battery Charging Steps:

1. Connect two 12V batteries in series. 2. Plug into household 220V power supply. 3. Select the corresponding mode. 4. Red clamp to positive pole, black clip to negative electrode. Start charging.

4. Operating Instructions

Charger Modes:

The charger features seven distinct modes. It is crucial to select the correct mode for your battery type to ensure safe and effective charging.

• AGM (LiFePO4) Mode: For AGM or LiFePO4 batteries.
• CAR Mode: For conventional rechargeable, dry, wet, lead-acid, maintenance-free, GEL, SLA, WET, DEEP CYCLE, EFB, and Calcium batteries.
• MOTO Mode: For small batteries, various types of motorcycle lead-acid batteries, and small capacity batteries.
• REPAIR Mode (16 hours): An advanced battery recovery mode for repairing and restoring old, idle, damaged, stratified, or sulfated batteries. Note: Not all batteries can be recovered, and this mode is only for Motorcycle and Car batteries.

LED Display Indicators:

The LED display provides real-time feedback on the charging process and battery status.

7-Stage Charging Process:

1. Stage 1: Battery Desulphation
2. Stage 2: Soft Start Charging
3. Stage 3: Bulk Charging
4. Stage 4: Absorption Charging
5. Stage 5: Battery Test
6. Stage 6: Recondition Charging
7. Stage 7: Float & Maintenance Charging

Seasonal Charging:

The charger automatically adjusts charging voltage based on temperature to prevent overcharging in summer and ensure full charge in winter (Car mode only).

• Winter Mode: When the temperature is below +10°C, the charger raises the charge voltage (Car mode only).
• Summer Mode: When the temperature is above +28°C, the charger reduces the charge voltage (Car mode only).

5. Maintenance

• Always unplug the charger from the AC outlet before performing any cleaning or maintenance.
• Wipe the charger's exterior with a soft, dry cloth. Do not use harsh chemicals or abrasives.
• Ensure the cooling fan vents are clear of dust and debris to maintain proper airflow.
• The charger can be left connected to the battery for extended periods to provide maintenance charging, keeping the battery optimally charged.

6. Troubleshooting

If you encounter issues with your charger, refer to the LED display for error codes and follow these steps:

• Wrong Polarity (ERO): If the display shows 'ERO' or indicates wrong polarity, immediately disconnect the clamps and re-connect them correctly (Red to positive, Black to negative).
• Defect Battery: If the charger indicates a 'Defect battery' error, have your battery professionally checked. It may need to be replaced.
• Bad Connection: If charging does not start or an error related to connection appears, check all connections between the charger, battery, and AC outlet to ensure they are secure and clean.
• Low Voltage (LOW): If the battery voltage is too low for the charger to initiate a standard charge, the charger will attempt to enter Desulphation mode (if applicable) or indicate 'LOW'. Ensure the battery is not severely damaged. The charger can start charging from a minimum of 5.0V.

7. Specifications

8. User Tips

• LiFePO4 Compatibility: This charger is fully compatible with LiFePO4 lithium batteries. Ensure you select the correct 'AGM LiFePO4' mode for these battery types.
• Low Voltage Start: The charger is designed to initiate charging even on very low voltage batteries, down to 5.0V. This can be particularly useful for deeply discharged batteries.
• Mode Selection: Always double-check that you have selected the appropriate charging mode for your specific battery chemistry to prevent damage and ensure optimal charging.
