Flat Battery- Windows Open !!

[wesacosa]

Hi all

Just joined here as something odd seemed to have happened on my GFs 2005 Boxster.

We came back from 2 weeks away over Christmas to find that both the drivers and passenger side window were open half way, and the rear boot was also unlocked.

Upon closer inspection the battery was totally dead. Nothing at all would work. I connected up a 12v booster to the battery and got enough power to close the windows.

The battery is a Halfords battery , 12 months old. So far it has not given any problems what so ever.

So my question is, is it possible that the windows and boot opening could be caused by a battery getting low on voltage (seems like a crazy and very unsafe situation if leaving a car for less than 2 weeks would cause it to be come open to any thief who happened to be passing) or could something have gone crazy with the electrics and it was the opening and closing of windows which killed the batterY? Any ideas would be greatly received.

Thanks
Wes
