It's likely that you could return a year from now and the car would still start.. To extend your battery life you could disconnect the battery.. Most newer cars drain the battery a little just to power the alarm, and other very low drain electronics.. For two weeks, or even two months, I wouldn't worry about it.. Cruise, and enjoy..
