This video show the location of the battery on a Jaguar XKR and Jaguar XK. I have undo the bottom bracket being held by two 10 mm bolts and once I had that off you can remove the 2 nuts holding the bottom part of the battery at about 0:27 you can see the 2 nuts, on the left, one of the 2 bolts to get the bottom bracket out. It is important to match up the proper numbers when replacing the battery. This vehicle unlike many required that I purchase the battery from the Jaguar dealer since no other source carried the proper battery.
