I have a 2012 Lincoln MKS Ecoboost. My battery light came on last week. Then my car wouldn't start, so I went and bought a new battery. I usually leave my car parked for maybe 10 hours at a time cause I'm in a company truck. Anyways the light still comes on when I start the car. I have no trouble starting the car, I drive maybe 6 miles or so then the battery light turns off. What am I dealing with here. I try to make it to AutoZone before the battery light turns off. They said they can't test the battery to find an issue if the light isn't on.
