On the 2001 XJ8 it is in the right side of the trunk under the false trunk floor. I suspect that the 2002 model is the same.
The Battery is located in the truck of the car on the passenger side. There is a removal panel covering it. To access it when the battery is dead, attach jumper cables as you would to jump the car and depress the truck opening button on the dash.
