The second clamp body is coupled to the first clamp body. The handle assembly is selectively disposed through each of the first clamp body and the second clamp body. Each of the first clamp body and the second clamp body define an aperture having a substantially polygonal cross-section configured to receive a battery post. Each of the first clamp body and the second clamp body have an internal wall with a plurality of ridges configured to selectively abut the battery post. The first clamp body and the second clamp body are hingedly connected. ## Claims ### Claim 1 A quick change battery clamp configured to be reversibly coupled to a battery post, comprising: a first clamp body;
