Mine is a 2007 - they left the battery tray in the original location - drivers side corner all the way to the front - easy to get to - but they installed the battery on the passenger side all the way in the back of the engine compartment.
It is wedged in between between some hoses - maybe one from the AC and the coolant reservoir tank. You need to remove a bracket & it looks like you will have just enough space to pull the old battery out without removing the hood.
I don't understand why they left the second battery tray in place - I always figured maybe they were thinking about a diesel option so they would have two batteries.
