This is not to mention that one has to unfasten the battery tray to allow the battery to tip backwards (so it can slide up), remove a variety of brackets in order to unfasten the battery tray, remove the side panels so that one can access the bolts that hold the tray, and remove half the wiring harness so that one can slide the battery out. Oh, and to actually extract the battery from between the frame rails, one must use a pry bar, because the battery is physically wider than the space through which it must pass. Now I think I have a better image of childbirth.
Seriously? This is the famed German engineering which has won BMW so much acclaim? Hmph. Well, at least the battery is out and charging, on the off chance that it's still functional despite only showing 6.72 volts. However, even if it does hold a charge, I'm not sure I will re-install it, because I don't want to try to reverse the process, nor deal with this again in a few years. Time for a smaller yet more-powerful, modern battery.
