Both sides will have a 10 mm nut to be loosened on both the positive and the negative. First release the negative side.

Remove screws 13 mm or 10 mm.

 

To remove the positive terminal cover...this is a big fuse panel actually...you will need to unclip the connectors / wiring that go into the plugs...there is a tab to press and then it slides out. For the cover it has two metal arms that lock it to the battery. If you slide a screw driver into the metal retainer along the side of the battery and press it out it should unclip from the retainer so it can be lifted off. You will have to do this on both sides. I will also add the instructions below withs some pics.
