In preparation for the arrival of my new purchase can anyone tell me where the battery is located in a Crossfire, is it under the bonnet or in the boot?

My car will be used at weekends mainly and as it will spend quite a lot of time sitting in the garage it will be connected to a battery maintainer and i'm just trying to work out if I need to use an extension lead or not.

If anyone has a photo of the actual battery location it would be helpful
