2. Safety Information
Please read and understand all safety information before using this product. Failure to follow these instructions may result in electric shock, fire, or serious injury.
- Indoor Use Only: This charger is designed for indoor use. Do not expose it to rain or moisture.
- Ventilation: Ensure adequate ventilation during charging. Do not cover the charger.
- Battery Compatibility: Only use this charger with 12V lead-acid batteries (Calcium, GEL, AGM, Wet, EFB) within the 2Ah-100Ah capacity range. Do not attempt to charge lithium batteries or other battery types.
- Polarity: Always connect the charger clamps to the correct battery terminals (red to positive, black to negative). The charger has polarity protection, but correct connection is crucial.
- Connection Sequence: Connect the charger to the battery first, then plug it into the power source. When disconnecting, unplug from the power source first, then remove the battery clamps.
- Avoid Shock: Do not carry the charger with the vehicle to prevent shock or damage.
- Damaged Equipment: Do not operate the charger if it has been dropped, damaged, or exposed to water.
3. Setup and Connection
- Prepare the Battery: Ensure the battery terminals are clean and free from corrosion. If necessary, clean them with a wire brush.
- Connect the Clamps:
- Connect the red (+) clamp to the positive terminal of the battery.
- Connect the black (-) clamp to the negative terminal of the battery.
- Connect to Power: Plug the charger's power cord into a standard AC 110-220V, 50-60Hz electrical outlet.
- Start Charging: The charger will automatically detect the battery and begin the charging process. The LCD display will show the charging status.
4. Operating Instructions
4.1 Charging Process
Once connected and powered, the charger will automatically initiate the charging process. The LCD display provides real-time information:
- Voltage Display: Shows the current battery voltage.
- Charge Level Indicator: A five-stage power display (20%, 40%, 60%, 80%, Full) indicates the battery's charge progress.
- Mode Indicators: Icons for Winter/Summer mode, Pulse Repair, and various protections will be visible as applicable.
4.2 Automatic Temperature Detection
The charger automatically adjusts the charging voltage based on the ambient temperature to ensure optimal and safe charging:
- Winter Mode: Automatically enters winter mode below 10°C for powerful charging in cold conditions.
- Summer Mode: Automatically enters summer mode above 28°C for safety charging in hot conditions.
4.3 Smart Repair Function (Pulse Repair)
The charger features a low-frequency pulse repair technology designed to address common battery issues:
- Conditions Addressed: Car long idle time, low voltage and weak power, battery aging, and inability to hold a charge.
- Activation: The charger will automatically engage the repair mode when it detects a suitable battery condition. The LCD will show 'Recovery'.
4.4 Charging Current Adjustment
The charger supports manual selection of charging current to suit different battery capacities and charging needs. Press the 'MODE' button to cycle through available current options:
- Available currents: 5.5A, 5.0A, 2.0A.
- Selecting a lower current is generally safer for smaller batteries or for a slower, more thorough charge.
4.5 Disconnecting the Charger
- First, disconnect the charger from the main power source (unplug from the wall outlet).
- Then, remove the black (-) clamp from the negative battery terminal.
- Finally, remove the red (+) clamp from the positive battery terminal.
5. Maintenance
- Storage: Store the charger in a dry, cool, and well-ventilated area when not in use. Keep it away from direct sunlight, heat sources, and moisture.
- Cleaning: Clean the exterior of the charger with a soft, dry cloth. Do not use solvents or abrasive cleaners. Ensure the cooling fan vents are clear of dust and debris.
- Cable Inspection: Regularly inspect the power cord and charging cables for any signs of damage, fraying, or exposed wires. Do not use if damaged.
- Handling: Handle the charger with care. Avoid dropping it or subjecting it to strong impacts.
6. Troubleshooting
The EAFC Smart Pulse Battery Charger is designed with multiple protections to prevent damage and ensure safe operation. If the charger is not functioning as expected, consider the following:
- Charger Not Starting:
- Ensure the charger is properly plugged into a live power outlet.
- Check that the battery clamps are securely connected to the correct terminals (red to positive, black to negative). The charger has non-battery link protection and polarity protection, which will prevent operation if connections are incorrect or absent.
- Verify the battery voltage is above the minimum start voltage of 8.0V. If the battery is severely discharged below 8.0V, the charger may not initiate charging.
- Charging Stops Unexpectedly:
- The charger has overcharge, overheating, and short circuit protection. If any of these conditions are detected, the charger will automatically stop or pause charging. Check for excessive heat, ensure proper ventilation, and inspect for any short circuits.
- The charger may have completed the charging cycle. Check the LCD display for a 'Full' indication.
- Battery Not Charging Effectively:
- Ensure the battery capacity (Ah) is within the charger's specified range (2Ah-100Ah).
- Consider using the pulse repair function for batteries that have been idle for long periods, have low voltage, or are showing signs of aging.
- Verify the selected charging current is appropriate for your battery.

8. User Tips
- Check Battery Capacity: Always verify the capacity (Ah) of your battery before connecting the charger to ensure it falls within the 2Ah-100Ah range.
- Optimal Charging: For smaller batteries or for a gentler charge, consider manually selecting a lower charging current (e.g., 2.0A) using the 'MODE' button.
