Yes, I've already done the search, in fact I spent most of Sunday afternoon, while the E93 was stranded in the driveway with a battery charger attached reading two years worth of battery threads; so here goes:
Two or three times in the last 4 weeks the car has choked and sputtered a little while starting, but never has it had significant trouble turning over. I've never had any battery low warnings.
This weekend was car detailing weekend, so there were 4 consecutive starts which amounted to starting the car moving it either out of or into the garage then shutting it off. On the 5th time, when I was finished with my work and was ready to get in the car and run an errand, the car suddenly wouldn't start at all. BTW: I have done this type of pattern of starts and stops before and never had any ill effects.
When we hooked the car to the battery charger on the 6 amp setting the needle immediately pegged at 6 amps and it took about 3.5 hours to get the battery charged enough to start the car up and get it moved back into the garage. We then put the battery charger back on it, on the "trickle" setting and continued to let it charge for another hour until it indicated that it was at capacity. Interestingly, while the car was on the charger in the garage, just doing things like opening the doors, opening the trunk would cause the draw on the battery charger to spike again to 6 amps and then it would gradually return to 2 amps. When charged to capacity, we unplugged everything and let the car sit overnight. This morning, enough charge had dropped that the battery charger was again indicating 3.5-4 amps when attached to the car and plugged in.
At noon we took the car and made a short trip. When SO got back home with it he again checked it with the battery charger and again the charger spiked at 6 amps then slowly came back down to two amps.
THe car DOES NOT have Comfort Access so I wasn't draining the battery with the CA system this weekend. I also do not have i-drive, so no parasitic drain there.
As I am still in warranty, the car is scheduled for a visit to the dealership in the morning, but would appreciate hearing what input knowledgable 'festers might impart.
TIA
