4. Operating Instructions
4.1 Automatic Charging Process
The FOXSUR charger is fully automatic with a 3-stage charging process. Once connected to a battery and plugged into power, it will automatically detect the battery type (6V or 12V) and begin charging.
- Stage 1: Desulfation (if needed): Applies a high-frequency pulse charge to break down lead sulfate crystals that may have built up on discharged batteries.
- Stage 2: Bulk Charge: Charges the battery at its maximum rate (2 Amps) until it reaches approximately 80% capacity.
- Stage 3: Float Charge: Once the battery is fully charged, the charger switches to a lower voltage to maintain the battery at 100% capacity without overcharging. This allows the charger to be left connected indefinitely.
4.2 LCD Display Information
The backlit LCD display provides real-time feedback:
- Voltage (V): Displays the current battery voltage.
- Current (A): Shows the charging current in Amperes.
- Charging Status: An animated battery icon indicates the charging progress.
- Battery Full: Displays 'FUL' when the battery is fully charged.
- Error (ERO): Indicates a fault condition (e.g., reverse polarity, short circuit).
- Repair Mode (PUL): Indicates the pulse repair function is active.
- End Repair (End): Indicates the pulse repair cycle is complete.

4.3 Pulse Repair Function
This charger includes a pulse repair function designed to help restore sulfated or slightly discharged batteries and extend their lifespan. The charger will automatically engage this mode if it detects a suitable condition. Note that this function cannot activate completely dead batteries or repair severely damaged batteries to a new condition.
5. Maintenance
Proper maintenance ensures the longevity and safe operation of your battery charger.
- Cleaning: Disconnect the charger from power and the battery. Wipe the exterior with a soft, dry cloth. Do not use harsh chemicals or abrasives.
- Cable and Clamp Inspection: Regularly inspect the charging cables and clamps for any signs of damage, fraying, or corrosion. Replace if necessary.
- Storage: Store the charger in a cool, dry place when not in use. Avoid extreme temperatures and direct sunlight.
6. Troubleshooting
If you encounter issues with your FOXSUR battery charger, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Charger does not turn on or display anything. | No AC power; loose connection; faulty outlet. | Check AC power connection. Ensure outlet is functional. Verify charger is properly plugged in. |
| Display shows 'ERO' (Error). | Reverse polarity; short circuit; battery voltage too low/high; incorrect battery type. | Disconnect and re-connect clamps ensuring correct polarity (+ to +, - to -). Check for short circuits. Ensure battery is a compatible lead-acid type and within the 4Ah-40Ah range. |
| Charger not charging or charging slowly. | Battery severely discharged/damaged; poor connection; charger fault. | Ensure clamps have good contact. Note that the charger cannot activate completely dead batteries or repair severely damaged ones. If the issue persists, contact support. |
| Charger feels warm during operation. | Normal operation; poor ventilation. | Some warmth is normal. Ensure the charger has adequate ventilation and is not covered. If it becomes excessively hot, disconnect immediately and contact support. |
If the problem persists after attempting these solutions, please contact FOXSUR customer support.
