5. Maintenance
To ensure the longevity and optimal performance of your NOCO Boost GB150, follow these maintenance guidelines:
- Regular Charging: Recharge the unit after each use and at least every 3-6 months to maintain battery health, even if not used.

6. Troubleshooting
If you encounter issues with your NOCO Boost GB150, refer to the following common troubleshooting tips. For more detailed information, consult the full user guide.
- Unit Not Turning On: Ensure the unit is sufficiently charged. If the battery is completely depleted, it may take a few minutes of charging before the unit responds.

The GB150 has reverse polarity protection, which will prevent operation if connections are incorrect.

- Error LED Blinking: The Error LED (red exclamation mark) indicates a problem. The number of blinks (1 to 6) conveys specific error conditions. Refer to the user guide for a detailed explanation of error codes and their solutions.
