5. Operating Instructions
5.1. 10-Stage Charging Process
The charger utilizes an advanced 10-stage charging process for optimal battery health and longevity:
- **Diagnosis**: Checks battery status.
- **Battery Desulphation**: Breaks down lead sulfate crystals.
- **Pre-Charging**: Initial gentle charge.
- **Soft Start Charging**: Gradually increases current.
- **Bulk Charging**: Charges battery to approximately 80% capacity.
- **Constant Current Charging**: Maintains a steady current.
- **Constant Voltage Charging**: Maintains a steady voltage.
- **Absorption Charging**: Fully charges the battery.
- **Float Charging**: Maintains battery at full charge.
- **Re-start Charge after Battery Discharged**: Automatically restarts charging if battery voltage drops.

5.2. Multiple Charging Modes
Select the appropriate mode for your battery type using the 'MODE' button:
- **CAR**: For GEL, SLA, WET, DEEP CYCLE, EFB batteries.
- **AGM**: For AGM batteries.
- **CA**: For Calcium batteries.
- **LiFePO4**: For LiFePO4 batteries.
- **MOTO**: For Motorcycle batteries.
- **REPAIR**: An advanced battery recovery mode (16 hours) for repairing and restoring old, idle, damaged, or stratified batteries.
- **SUPPLY**: 12V Power Supply mode for charging batteries with voltage lower than 5V, or converts to a DC power supply for powering 12VDC devices like a DC Fan, cell phone charger, or as a memory retainer when replacing a battery.

5.3. Pulse Repair Function
The "REPAIR" mode uses pulse technology to address issues like poor battery usage, inability to charge old batteries, or high internal resistance. This mode can help activate and restore batteries, extending their lifespan.

5.4. Auto Temperature Detection
The charger automatically adjusts the charging voltage based on the ambient temperature, ensuring optimal charging performance in both winter and summer conditions.

6. Maintenance
- **Cleaning**: Regularly wipe the charger's exterior with a soft, dry cloth to remove dust and debris.
- **Cable Management**: Utilize the winding cable design on the back of the charger for neat storage of the power cord and clips.
- **Storage**: Store the charger in a cool, dry place when not in use.
- **Pulse Repair**: Use the "REPAIR" mode periodically for older or underperforming batteries to help maintain their condition.

7. Troubleshooting
The FOXSUR FAC-150 includes several safety features to prevent common issues:
- **Short-Circuit Protection**: If the positive and negative clamps are accidentally short-circuited, the charger will display "ERO" (Error) and stop charging to prevent damage. Disconnect the clamps and reconnect them correctly.
- **Reverse Connection Protection**: If the battery clamps are connected to the wrong terminals (positive to negative, negative to positive), the charger will display "ERO" and stop charging. Correct the connections before proceeding.
- **Overvoltage/Low Voltage Protection**: The charger will automatically protect against overvoltage and low voltage conditions.
- **Overcurrent Protection**: Prevents damage from excessive current draw.
- **Electric Shock Protection**: Designed with safety in mind to minimize electric shock risks.
- **Fire Protection**: Incorporates features to reduce fire hazards.
If the charger displays "ERO" or does not start charging, check all connections and ensure the correct mode is selected for your battery type. If problems persist, contact customer support.
