My battery light is on.

My battery light came on Friday on my 2010 Avenger. I just replaced the alternator a year or so ago. I changed the battery this weekend and after 10 minutes or so of driving the battery light came back on. Does anyone know if anything other than the battery or alternator will cause the battery light on my dash to come on?

You need to do diagnosis. Just because you replaced the alternator doesn't mean it can't be bad again. You need to check battery voltage with the car off, then with it running. This will confirm if the alternator is charging or not. A bad battery generally eont kick a battery light, it just won't let the car start. Once a vehicle is running most of the electrical is handled by the alternator.
