Low Battery
Have a 2013 Ford Fusion Battery is 1 year old and passed being tested.
About every two weeks I will get the warning message on the radio for low
battery power saver mode and the car will be difficult to start. I then charge
the battery over night and no problems for about another 2 weeks. Had the
alternator tested and they said it wasn't charging the battery so i replaced it
and 2 weeks later i am having the same problem. Only seems to be a
problem now that its cold out. car is parked in garage overnight, i drive 4
miles to work in the morning and 4 miles home at night.
