First dead battery this morning. C-Max SE purchased in February. 1340 miles. No options. Never used any 12v ports. Jumped from 12v trolling battery. Buying emergency starter battery today. Next time will call Ford Emergency service if not in a hurry or not in my garage. Nothing worked at all. Doors were unlocked since car was in garage. Rear hatch would not open so I won't store jumper cables there again. Clock has correct time after jump start. Car is used 3 or 4 times a week with nearest anything being 9 miles. Most trips are 25 miles round trip.
