Both the Bently service manual and the BMW TIS call for resetting the computer when the battery is replaced. You can replace the battery and not reset the computer, but the car will not properly charge the new battery. I'm sure the dudes at walmart in McAlester, OK know better than the BMW TIS and Bently publishing that as been developing BMW repair manuals since the 1980's based on actual repair of BMWs.
