8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Charger does not power on. | No power supply; incorrect power connection. | Check AC cable or DC input connection. Ensure power source is active. |
| Battery not recognized. | Incorrect battery connection; non-G-Tech battery (manual settings required); damaged battery. | Ensure main and balance leads are securely connected. For non-G-Tech batteries, manually set parameters. Inspect battery for damage. |
| Charging process stops prematurely. | Battery full; safety cutoff triggered (over-voltage, over-current, over-temperature); poor connection. | Check battery status on display. Verify connections. Allow charger to cool if overheated. |
| Error message on display. | Specific error condition (e.g., "Cell Voltage Error", "Connection Error"). | Refer to the specific error code on the display for detailed instructions. Usually indicates a battery or connection issue. |
