2. Important Safety Instructions
Always read and understand all safety warnings and instructions before using the charger. Failure to follow these instructions may result in electric shock, fire, or serious injury.
- Ventilation: Ensure adequate ventilation during charging. Do not operate the charger in a confined area or restrict ventilation.
- Battery Type: This charger is designed for 12V and 24V lead-acid batteries (Calcium, Gel, AGM, LiFePO4, Wet). Do not attempt to charge dry-cell batteries that are commonly used with home appliances.
- Polarity: Always connect the red (+) clamp to the positive battery terminal and the black (-) clamp to the negative battery terminal. Ensure correct polarity before connecting to AC power.
- Sparks: Avoid creating sparks when connecting or disconnecting the clamps. Connect the output clamps to the battery and then connect the charger to the AC power supply. Disconnect AC power first, then remove the battery clamps.
- Water Exposure: Do not expose the charger to rain or excessive moisture.
- Damage: Do not operate the charger if it has been dropped, damaged, or if the power cord or clamps are damaged. Contact customer support for assistance.
- Children: Keep the charger out of reach of children. The button will lock automatically after approximately 2 seconds of charging to prevent accidental touching.
- Temperature: The charger automatically adjusts charging voltage based on ambient temperature. Avoid extreme temperatures.

4. Setup and Connection
Follow these steps to safely connect the charger to your battery:
- Identify Battery Terminals: Locate the positive (+) and negative (-) terminals on your battery. The positive terminal is usually marked with a plus sign and is larger in diameter.
- Connect Red Clamp: Connect the red (+) charger clamp to the positive (+) terminal of the battery.
- Connect Black Clamp: Connect the black (-) charger clamp to the negative (-) terminal of the battery.
- Connect to AC Power: Plug the charger's AC power cord into a standard 100-240V AC, 50-60Hz electrical outlet.
- Verify Connection: The charger's display will illuminate, indicating a successful connection and beginning the charging process.
Important: Always connect the clamps to the battery first, then plug the charger into the AC outlet. When disconnecting, unplug the charger from the AC outlet first, then remove the clamps from the battery.

5. Operating Modes
The charger automatically detects the battery voltage (12V or 24V) and offers various charging modes. Use the "MODE" button to select the appropriate charging mode for your battery type:
| Mode Icon | Mode Name | Description |
|---|---|---|
| AGM | AGM Batteries Mode | For AGM batteries. |
| CAR | CAR Batteries Mode | For GEL, SLA, WET, DEEP CYCLE, EFB, and Calcium batteries. |
| MOTO | Motorcycle Batteries Mode | For Motorcycle batteries. |
| LiFePO4 | LiFePO4 Batteries Mode | For LiFePO4 batteries. |
| REPAIR | Repair Mode (16 hours) | An advanced battery recovery mode for repaired and old, idle, damaged, or sulfated batteries. Select this mode before connecting the battery; otherwise, the mode button will be locked. |
Once the appropriate mode is selected, the charger will automatically proceed through its 7-stage charging process. The display will show the current charging status.

6. Maintenance
Proper maintenance ensures the longevity and optimal performance of your charger:
- Cleaning: Disconnect the charger from AC power and the battery before cleaning. Wipe the exterior with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners.
- Storage: Store the charger in a cool, dry place when not in use. Ensure the cables are neatly coiled and not kinked.
- Cable Inspection: Periodically inspect the power cord and battery clamps for any signs of damage, fraying, or corrosion. Replace if necessary.
- Ventilation: Ensure the cooling fan and vents are free from dust and debris to maintain proper airflow.
7. Troubleshooting
If you encounter issues with your charger, refer to the following common problems and solutions:
- Charger Not Turning On:
- Check if the AC power cord is securely plugged into a live outlet.
- Ensure the battery clamps are correctly connected to the battery terminals (red to positive, black to negative).
- Verify the AC outlet is functioning by plugging in another device.
- "FUL" or "Battery Full" Displayed Immediately:
- The battery may already be fully charged.
- Ensure the battery voltage is within the charger's operating range (6-180Ah).
- "ERR" or Error Code Displayed:
- Indicates a fault. Check for reverse polarity connection, short circuit, or an open circuit (non-battery link).
- The battery might be severely damaged or completely dead, which the repair mode cannot fix.
- Charger Overheating:
- Ensure the charger's ventilation fan and vents are not blocked.
- Operate the charger in a well-ventilated area.
If the problem persists after attempting these solutions, please contact customer support.
