I leave my Boxster unlocked, top down, for 2-3 weeks at a time and it starts right up. I have a battery in excellent condition and when I drive the car it is for relatively long distances so the "juice" used in the starting is more than replaced. If I plan to leave it 3 weeks, I do use a battery maintainer plugged into the lighter socket.

Only downside of leaving it with the top down is dust in the cabin. And you have to be careful of the temperature if you have a '97-'02 986 but that doesn't apply to you.

You don't have to buy a Porsche branded battery, just one with the correct group size, cold cranking amps and vent hose (unless you want a truely sealed battery like an Optima).
