Setup and Connection
Follow these steps to safely connect the charger and begin the charging process:
- Connect to Power: Plug the charger's AC power cord into a standard household 100-240V AC, 50-60Hz electrical outlet.
- Select Battery Type Mode: Press the "MODE" button on the charger to cycle through and select the appropriate charging mode for your specific battery type (Car, Moto, AGM/LiFePO4, or Repair). The selected mode will be clearly indicated on the digital display.
- Connect to Battery:
- Connect the RED positive (+) charging clip to the positive (+) terminal of the battery.
- Connect the BLACK negative (-) charging clip to the negative (-) terminal of the battery.
The charger is designed to allow charging of batteries while they are still installed in the vehicle, provided there is adequate ventilation and safe, unobstructed access to the battery terminals.
Operating Instructions
Once properly connected, the charger will automatically detect the battery voltage and commence the charging process. The large HD screen display provides real-time information about the charging status.
Display Information:
- Voltage: Displays the current voltage of the battery.
- Current: Shows the charging current in Amperes (A).
- Power: Indicates the charging progress or the current power level.
- FULL: This indicator illuminates when the battery has reached a full charge.
- Mode Indicators: Icons representing the selected charging mode (Car, Moto, AGM/LiFePO4, and Repair).
Operating Modes:
Use the "MODE" button to select the appropriate charging program for your battery:
- Car Mode: This is the most frequently used mode, suitable for standard car batteries, including dry, wet, lead-acid, and maintenance-free types.
- Motorcycle Mode: Specifically designed for smaller capacity motorcycle batteries and various types of motorcycle lead-acid batteries.
- AGM/LiFePO4 Mode: Optimized for charging AGM (Absorbent Glass Mat), EFB (Enhanced Flooded Battery), and LiFePO4 (Lithium Iron Phosphate) battery chemistries. These types often have distinct charging requirements.
- Repair Mode: Activates a specialized repair process intended to address issues such as battery sulfation or high internal resistance. This mode can help improve the battery's ability to accept and hold a charge.
Maintenance
Proper maintenance of your FOXSUR battery charger will ensure its longevity and optimal performance:
- Keep the charger clean and dry. If cleaning is necessary, wipe the exterior with a soft, slightly damp cloth. Do not use harsh solvents or abrasive cleaning agents.
- Regularly inspect the charging cables and clips for any signs of wear, cuts, or damage. Replace any damaged components immediately to prevent safety hazards.
- Ensure that the cooling fan vents are kept clear of dust, debris, and obstructions to allow for proper airflow and heat dissipation.
- When not in use, store the charger in a cool, dry environment, away from direct sunlight and extreme temperatures.
Troubleshooting
If you encounter issues with your charger, refer to the table below for common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Charger not turning on. | No power from the electrical outlet; loose power cord connection. | Verify the power outlet is functional. Ensure the charger's power cord is securely plugged into both the charger and the outlet. |
| Charger not initiating charge to battery. | Incorrect battery connection (reverse polarity); battery voltage too low (below 8.0V); battery severely damaged. | Ensure correct polarity (+ to +, - to -). If battery voltage is below 8.0V, the charger may not initiate. Try the 'Repair' mode for sulfated batteries. If the issue persists, the battery may be beyond repair. |
| Charger displays an error message or warning. | Over temperature, short circuit, reverse polarity detected. | Disconnect the charger from both power and battery. Check all connections for proper polarity and shorts. Allow the unit to cool down if overheated. Reconnect carefully. |
| Battery not holding charge after charging. | Battery is old or internally damaged; significant sulfation. | Attempt to use the "Repair" mode for an extended period. If the battery still fails to hold a charge, it likely needs to be replaced. |
