2008 Cayman S - Battery question

[Johnniem]

Am wondering what the likely condition of a battery will be after being away for around 17 days. I realise that the car will shut various background equipment after a week but is there still a chance that the battery will be flat after such a time. I could leave the TVR Chimaera for several weeks with no detrimental effect but have limited knowledge of this scenario with my new (to me) Cayman.

By the way, I love the car!!

Thanks for all your comments. Looks like it could be ok.
