I just picked up an OEM 720 CCA/90 Ah (exact specifications as my original battery on my '08) from the BMW dealer today. I took it to an independent shop to have them install and register for a slightly less insane amount than the dealership wanted. Parked the car at home and when I went to drive it ~3 hours later I got the warning "increased battery discharge" at startup and the time had been reset again. The message stuck around for a few minutes and then I turned the car off and back on to make it go away.

Any ideas? Is it a bum battery? Was it not registered properly? Why is everything that should be simple so complicated on this car?!
