2. Safety Information
Always observe the following safety precautions to prevent injury or damage to the charger or battery:
- Ensure the charger is connected to a 110-220V AC power source.
- Do not charge non-rechargeable batteries.
- Avoid charging frozen or damaged batteries.
- Operate in a well-ventilated area.
- Keep out of reach of children.
- Do not expose the charger to rain or excessive moisture.
- Disconnect the AC power before connecting or disconnecting battery clamps.
- Ensure correct polarity: Red clamp to positive (+), Black clamp to negative (-).
3. Product Features
- Microprocessor-controlled for automatic operation.
- Compatible with most 12V lead-acid batteries, including Calcium, GEL, AGM, Wet, and EFB types.
- LCD display for real-time charging status.
- Pulse repair function to help restore battery performance.
- Integrated protections: Overheat, overcharge, short circuit, and reverse polarity.
- Automatic adjustment of charging voltage for winter and summer conditions.
4. Setup and Connection
- Prepare the Battery: Ensure the battery terminals are clean and free of corrosion. If charging an in-vehicle battery, ensure the vehicle's ignition is off and all accessories are disconnected.
- Connect to Battery:
- Connect the red positive (+) clamp to the positive (+) terminal of the battery.
- Connect the black negative (-) clamp to the negative (-) terminal of the battery.
- For in-vehicle charging, connect the black clamp to the vehicle chassis away from the battery and fuel line if the battery is not easily accessible.
- Connect to Power: Plug the charger's AC power cord into a standard 110-220V AC electrical outlet. The LCD display will illuminate.

5. Operating Instructions
- Automatic Detection: Once connected to power and battery, the charger will automatically detect the battery voltage and type.
- Mode Selection: Press the "MODE" button to cycle through available charging modes. The LCD display will show the selected mode (e.g., Car/Truck, AGM/GEL, Motorcycle, Repair).
Figure 3: Mode selection options on the EAFC charger, including modes for cars/trucks, AGM/GEL batteries, motorcycles, and a repair mode.
- Charging Process: The charger will begin charging automatically based on the selected mode and detected battery condition. The LCD will display charging progress, voltage, and current.
- Winter/Summer Mode: The charger automatically adjusts charging voltage based on ambient temperature.
- Winter Mode: Activated below 10°C (50°F) for optimal charging in cold conditions.
- Summer Mode: Activated above 27°C (80.6°F) for optimal charging in warm conditions.

- Completion: The charger will automatically stop charging when the battery is fully charged and switch to maintenance mode. The LCD will indicate "FUL" or 100%.
6. Maintenance
- Cleaning: Disconnect the charger from power and battery. Wipe the casing with a soft, dry cloth. Do not use solvents or abrasive cleaners.
- Storage: Store the charger in a cool, dry place when not in use. Ensure cables are neatly coiled and not kinked.
- Battery Maintenance: Regularly check battery terminals for corrosion and clean as necessary. Ensure battery fluid levels are adequate for non-sealed batteries.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Charger not turning on. | No AC power; faulty outlet; damaged power cord. | Check AC power connection and outlet. Inspect power cord for damage. |
| Charger not charging. | Incorrect battery connection (reverse polarity); battery voltage too low (below 8V); battery severely damaged. | Verify correct polarity. Ensure battery voltage is above 8V. If battery is severely damaged, it may not be rechargeable. |
| "ERR" or error code on display. | Internal fault; battery fault; short circuit. | Disconnect and reconnect the charger. If error persists, consult customer support. |
| Charger gets warm during operation. | Normal operation; poor ventilation. | Some warmth is normal. Ensure adequate ventilation around the charger. |
