6. Troubleshooting
If you encounter issues with your Palogreen batteries, please refer to the following common solutions:
- Battery Not Charging: Ensure the USB-C cable is securely connected to both the battery and the power source. Verify that the power source is active and providing 5V output. Try a different USB port or charging cable.
- Battery Not Powering Device: Check if the battery is fully charged using the tap-to-view LED indicator. Ensure the battery is inserted correctly into the device with the correct polarity (+/-). Some devices may require a specific type of battery; confirm compatibility.
- Battery Overheating During Charging: Use only standard 5V USB charging ports. Avoid using variable voltage chargers, as these can cause overheating. If a battery becomes untouchably hot within the first 10-20 seconds of charging, immediately disconnect it and use a different charger or device.
- Irregular Performance: Ensure batteries are fully charged before use. For optimal performance, avoid mixing new and old batteries or batteries of different types in the same device.
