This does not mean your battery is fine. I was a passenger in a friend's E46 M3 that had zero symptoms... none, nothing, nada! We drove a mile, turned off the car, ran an errand, and when we came back to the car, it would not start. The dash lit up and all sorts of weird stuff was going on. That was the symptom.

Fortunately he had another battery at home, so we walked to get it, returned in my car, installed it, problem solved.

Moral of the story is... you cannot rule out the battery simply because nothing appears wrong. I've read about it here and have first-hand experience that they can go at any time without warning. If it's 4 years old or older, you may be on borrowed time.
