How do you change battery on dyna super glide 2001?

The battery box has two bolts that hold the battery and cover tight against the frame. The first one to loosen is hard to find. It screws up into a threaded hole at the rearof the battery box. once loosened then you can loosen the other wich faces right at you, also at the rear of the box and then the battery cover can be removed and then the battery.
