4. Setup
- Prepare the Battery: Ensure the battery terminals are clean and free of corrosion. If charging a wet lead-acid battery, check the fluid levels and top up if necessary.
- Connect to Battery:
- Connect the RED positive (+) clamp to the positive (+) battery terminal.
- Connect the BLACK negative (-) clamp to the negative (-) battery terminal.
- For vehicle batteries, connect the negative clamp to the vehicle chassis away from the battery and fuel line if the battery is still in the vehicle.
- Connect to Power: Plug the charger's power cord into a standard 120V AC electrical outlet. The charger will power on and display the current battery status.

5. Operating Modes
The charger features 5 distinct operating modes, selectable by pressing the 'MODE' button on the device. The charger automatically detects the battery type and suggests a mode, but manual selection is possible.
- STD (Standard): For standard lead-acid batteries (Wet, Flooded).
- AGM/GEL: For AGM and Gel lead-acid batteries.
- MOTORCYCLE: Optimized for smaller capacity motorcycle batteries.
- LiFePO4: Specifically for 12V Lithium Iron Phosphate batteries.
- REPAIR: Pulse repair mode for desulfation and restoration of weak batteries.

6. Charging Process
The EAFC charger utilizes a 9-stage intelligent charging process to ensure optimal charging, battery health, and longevity.
- Battery Testing: Analyzes battery condition.
- Battery Desulfation: Breaks down sulfates that reduce battery capacity.
- Soft-Start Charging: Gradually introduces current to prevent damage.
- Constant Current Charging: Charges at maximum current until voltage rises.
- Constant Voltage Charging: Charges at constant voltage, current decreases.
- Battery Testing: Re-evaluates battery status.
- Battery Recovery Charging: Attempts to recover deeply discharged batteries.
- Float and Maintenance Charging: Maintains full charge without overcharging.
- Monitoring Phase: Continuously monitors battery for optimal health.

7. Pulse Repair Function
The built-in pulse repair technology helps to reduce sulfation and acid stratification in weak or underperforming batteries. This process can restore battery capacity and improve cold start performance. This mode is ideal for battery maintenance and occasional top-ups for batteries that are not severely damaged or completely dead.

8. Temperature Adaptive Charging
The charger automatically adjusts its charging performance based on the ambient temperature, ranging from -20°C to +60°C. This ensures stable and efficient charging in various climates.
- Winter Mode (below 10°C): Adjusts charging parameters for cold weather to prevent undercharging.
- Summer Mode (above 28°C): Adjusts charging parameters for hot weather to prevent overcharging.

9. Maintenance
To ensure the longevity and optimal performance of your EAFC battery charger:
- Keep the charger clean and dry. Wipe with a soft, damp cloth. Do not use harsh chemicals.
- Store the charger in a cool, dry place when not in use.
- Inspect the cables and clamps regularly for any signs of damage or wear. Replace if necessary.
- Ensure the cooling fan vents are clear of obstructions to prevent overheating.
10. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Charger not turning on | No power from outlet; loose connection; faulty charger. | Check power outlet; ensure secure connections; contact support if faulty. |
| Charging not starting | Incorrect battery connection (reverse polarity); battery too low/damaged; wrong mode selected. | Check clamp connections; try pulse repair mode (if applicable); ensure correct mode for battery type. |
| Charger overheating | Blocked vents; prolonged use in high temperatures. | Ensure vents are clear; move to a cooler environment; allow to cool down. |
| Display error message | Internal fault; battery issue. | Refer to specific error codes in a more detailed manual (if available) or contact support. |
