What would cause low battery light? Voltage while running is 14.5v. Voltage while off is 12.5v. Battery is only 8 mo old

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! Your F-150's voltage readings look healthy—14.5V while running and 12.5V when off are right where they should be, so that low battery light could be throwing you a curveball. Since the battery’s only 8 months old, and assuming it's not defective, the issue might lie in a loose or corroded battery terminal, a faulty ground connection, or even a glitchy alternator that's not consistently communicating with the vehicle's control module. Another possibility is a parasitic draw when the truck’s off, causing intermittent low voltage spikes that trigger the light. Double-check those connections, clean the terminals, and consider testing for a parasitic drain if the problem persists. It's a bit like playing detective, but hopefully, you'll catch the culprit soon!
