Haven't had any need to do this my self but a reading of the F10 forum talks of this being quite a different set up with a much more expensive AGM battery that is sensitive to losing charge and low voltage error codes if the car is driven less than 10 miles or so a day with the "regenerative braking" and efficient dynamics" complicating life.

Seems to me like getting a new battery would be similar to disconnecting and reconnecting the old one. I'd call my dealer before I disconnected the battery to be on the safe side.
