Well, in my opinion they are both off. If the vehcile set for an extended period of time and there is no one around to start it at least once a week and run run till it reached Operating temp. You don't have to drive it. Oh, and the run it for a minute and shut it off won't drain the battery. It won't charge it because it isn't run long enough.
Now, if there is no one around to start the vehicle then your best option would be to disconnect the batter cable or just remove from the vehicle and store it in a warm area.
Hope this helps.
