whats happening is the alt isnt pumping out enough to keep the battery happy. OR option #2 is your car has something left on like the bulb in the trunk all night that can cause your battery to go low.


had a 1999 durango we went to the airport to visit my grandma and grandpa we left 1 light on for 1 week and it drained the battery all the way down.

but in your case i would get the alt bench tested to see if its ok
