How to tell if NOCO GB40 is fully charged?

The NOCO GB40 has built-in LED indicators that show the charge level and allow you to determine if it’s fully charged. When charging, the LEDs will illuminate to indicate the current charge status. A solid green light indicates a full charge, while red or blinking lights may signal a low charge or charging in progress. Users often find these indicators helpful for monitoring battery status before an emergency. Pro tip: Check the LED indicators before leaving on a trip to ensure your jump starter is ready. However, if the indicators fail to respond, consider troubleshooting or contacting customer service as it may need servicing.
