Thanks.
I found this at DucatiMonster.org (for future reference)
Not as hard as you think. First get a 3 mm hex key and remove all the side panel screws and remove the screws that hold the cover around the gas filler cap, and remove the two plastic side panels. After the screws are out the side panels the panels slide forward and will come out. There are two hex screws (size ?) that have to be removed to release the
fuel tank. One is under the tank and is accessed from the rear with about a 1 foot extension for the hex bit. The other is on the front rt side and is quite obvious. There is enough fuel hose on the tank that you can simply prop-up the front of the tank with a piece or wood or anything convenient and get access to the battery. I put battery tender leads on my 696. Hardest part is removing all the small screws that hold the side panels and cover for the fuel tank. Hope this helps. My dealer showed me all the details before I did the job.
