6. Troubleshooting
| Problem | LED Indicator | Possible Cause | Solution |
|---|---|---|---|
| Battery not charging | No light | No power to charger or battery not inserted correctly. | Ensure USB-C cable is securely connected to a 5V/3A power source. Re-insert battery, ensuring correct polarity. |
| Battery not charging | Red flashing | Incompatible battery type (e.g., non-rechargeable, incorrect size) or faulty battery. | Ensure only AA Lithium-ion or NiMH rechargeable batteries are used. Try a different battery. If the issue persists, the battery may be faulty. |
| Battery not charging | Red solid | Charging error detected (e.g., short circuit, overvoltage). | Remove the battery and re-insert it. If the error persists, the battery may be damaged or the charger may have an internal issue. Discontinue use if the problem continues. |
| Slow charging | Flashing blue/green | Power source is not 5V/3A or cable is not suitable. | Ensure you are using a 5V/3A power adapter and a high-quality USB-C cable. Lower power sources will result in slower charging. |
