4. Operating Instructions
Charging Process: Once batteries are inserted and the charger is connected to power, the indicator lights above each slot will illuminate to show the charging status. The charger automatically detects the battery type and applies the suitable charging strategy. The TC-CC-CV three-stage intelligent charging protocol is used to reduce battery wear and improve lifespan.

5. Maintenance
- Cleaning: Use a soft, dry cloth to clean the charger and batteries. Do not use abrasive cleaners or solvents.
- Storage: Store the charger and batteries in a cool, dry place away from direct sunlight and extreme temperatures.
- Heat Dissipation: The charger features a hollow-out design which aids in heat dissipation during charging. Ensure the charger is placed in a well-ventilated area.
6. Troubleshooting
- Battery Not Charging:
- Ensure the charger is properly connected to a power source.
- Verify that the batteries are inserted with correct polarity.
- Check if the batteries are severely over-discharged; the BC8 has a revival function, but extremely damaged batteries may not recover.
- Ensure the power adapter meets the QC3.0 18W specification for optimal performance.
- Slow Charging:
- Confirm you are using a QC3.0 18W power adapter. Lower wattage adapters will result in slower charging.
- Ensure the USB cable is not damaged and is capable of supporting fast charging.
- Charger Indicator Lights Not Working:
- Check power connection.
- If only specific slots are affected, try different batteries to rule out battery issues.
