Operating Instructions

Once the cable is properly connected, the charging process will begin:

1. After connecting the USB end to a power source and the XH 3-pin connector to the battery, the charger will automatically detect the battery and begin charging.
2. Monitor the charging process. While the charger has built-in safety features, it is good practice to periodically check the battery and charger for any unusual heat or odors.
3. Once the battery is fully charged, disconnect the battery from the charger, and then disconnect the charger from the USB power source.

Note: The charging time will vary depending on the battery capacity and its current charge level.

Maintenance

Proper maintenance ensures the longevity and performance of your charging cable:

• Cleaning: Use a soft, dry cloth to clean the cable and connectors. Do not use liquid cleaners or solvents.
• Storage: Store the charging cable in a cool, dry place away from direct sunlight and extreme temperatures. Avoid kinking or bending the cable sharply.
• Inspection: Periodically inspect the cable for any signs of damage, such as frayed wires or bent pins. Do not use a damaged cable.

Troubleshooting

If you encounter issues with your charging cable, refer to the following common problems and solutions:

• Battery Not Charging:
  • Ensure the USB power source is active and providing DC 5V. Try a different USB port or adapter.
  • Verify that the XH 3-pin connector is securely attached to the battery.
  • Confirm the battery is a 7.4V Li-Ion type with an XH 3-pin connector.
  • Check the cable for visible damage.
• Slow Charging:
  • Ensure the USB power source can deliver sufficient current (e.g., 1A or more).
  • The charging speed is fixed at 1000mA output; if it feels slow, the battery capacity might be very high, or the input power source is insufficient.
• Charger or Battery Getting Hot:
  • A slight warmth is normal during charging. However, if it becomes excessively hot, immediately disconnect the charger and battery.
  • Ensure proper ventilation around the charger and battery.
  • Do not charge a damaged or swollen battery.
