Where is the battery and how do you remove it on a Harley Davidson sportster 1995?

there is a square box on the left side of the motercycle. Just to the lower right of this box is a nut on a stud. Loosen this nut and the band that goes over the top of this box will loosen. remove the band, remove the top of the Chrome box, and remove the body of the box. And there is the battery.
