The GMC Acadia, Chevy Traverse, and the Buick Enclave share the same vehicle platform. The battery location is behind the passenger seat under the floor. Also be on the look out during the fall of 2012 for the 2013 models. The 2013 models will have a center seat airbag in the driver seat that deploys to protect the driver and the passenger from each other.
Here are several posts on this vehicle platform:
