8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Charger not powering on / LEDs not lighting up. | No power supply; faulty USB cable; faulty power source. | Ensure USB cable is securely connected. Try a different USB port or power adapter. Test with a different USB cable. |
| Battery not charging. | Battery not inserted correctly; battery is faulty; charger slot is faulty. | Re-insert the battery, ensuring proper alignment. Try charging a different battery if available. Try the other charging slot. |
| Charging is slow. | Low current from USB power source; charging two batteries simultaneously. | Ensure your USB power source provides at least 1A. Charging two batteries simultaneously will result in 500mA per battery, which is slower than 700mA for a single battery. |
