On a 2002 Rendezvous it isn't necessary to remove the fuse box. You will have to unclip the fuse box then remove the bar. The fuse box is held on by a retaining clip attached by an 11mm screw. Metal bar over battery is attached by a 14mm hex screw behind the fuse box as well as by two 11mm hex screws attached to the front radiator frame.
Remove the battery terminals as you would any other car (positive first, then negative) and reverse the steps to put every thing back in. If the battery uses screw-on posts on the side facing the dashboard, those are 8mm posts and can be quite difficult to get at. There is also another 11mm screw holding down a retaining clip at the base of the battery. Battery comes out easiest diagonally toward the centerline of the car.
No need to mess with any bolts on the fuse box, Use a socket and extension for the bolt below the fuse box and the two 10mm bolts in front of the bar. then lif tup and slide out bar and loosen battery holddown bolt and remove after battery terminals are taken off.

I know what you are thinking. There is this huge bar cutting diagonally across the battery preventing it from coming out.

Then you should be able to wiggle the battery out. You should replace the bar when the new battery is in because that bar seems to be structural support for the car frame.
if you pop the hood and look to your left in the corner closet to you. that's the battery.
Clean battery terminals, then tighten down the battery cables. With the ignition key---like any other time.
