I am sure it is just a matter of using a different word to describe the same thing, but you want a battery tender not a battery charger. The former is computer controlled and keeps the battery in optimum condition. I leave my cars on battery tenders for about 5 months. A full tank with fuel stabilizer is good, as mentioned. As far as tires, I used to inflate them to the level Porsche says and then every two weeks or so push the car (not on the paint work) so that the tires are not resting on the same spot. I have since purchased Tire Cradles for every car we store, don't have to inflate or move the cars and no flat spots after years of using them.
