Yes drivers seat for a left hand drive Cali. You can see the plastic/rubber cover by sliding the seat all the way forward and pulling the grey trim panel on the back of seat base off. (it just clips on, pull from the top towards the bench seat). The battery is all the way to the back of the seat base.
As Mark above says to do anything with the battery the seat has to come out of the vehicle. Not that difficult to do but dont turn the ignition with the airbag plug disconnected or you will get a fault that only a dealer can reset.
