Having some problems with the '6 recently. Battery is only a few months old. I've charged it with a charger and then put it in the car. Worked fine for 5 days or so and then on the last day, each time I start it I hear it struggling more and more for 3 or 4 starts until it barely turns over, like a flat battery. Sometimes this magically cures itself and seems to just charge all of a sudden, regardless of distance traveled.
For example, left work on Friday and it sounded as though it was starting to struggle, 5 miles home and then went out later that evening, 3 miles struggling more so, 5 miles struggling even more and then won't start, so I jump it. Drive 0.5 miles home and then I manage to start it fine 3 consecutive times on my driveway, jumping into life as if nothing is wrong.
Any ideas?
Cheers
