6. Troubleshooting
- Battery Not Charging:
- Ensure the charging cable and charger are securely connected.
- Verify that the charger is compatible and providing sufficient power (e.g., 65W PD for USB-C).
- Check for any visible damage to the battery or charging ports.
- Battery Not Powering Devices:
- Confirm the battery has sufficient charge.
- Ensure the device is connected to the correct output port and the cable is secure.
- Check if the device's power requirements exceed the battery's output capabilities.
- OLED Display Not Working or Showing Incorrect Information:
- If the display is blank, the battery may be fully discharged or in a protective state.
- If issues persist, contact customer support.
- Automatic Shutdown: The battery features built-in protections (over-voltage, over-current, short circuit, over-discharge, over-heat, over-charge). If the battery shuts down unexpectedly, it may be due to one of these protections being triggered. Allow the battery to cool down or resolve the issue (e.g., reduce load) before attempting to use it again.
