You have to take the front passenger tire off and a plate under the wheel well to get to the battery.
Take both cables off. Remove old battery. Put new battery in. Put cables back on.
On the rear fender, undo the single screw. Then lift the seat, slide it back, and, finally, remove it. When you see the battery, undo the negative and positive terminal. Remove the battery from the box. Refit the battery doing the opposite of what you did when you removed the battery.
