The Modular Battery Pack 223 is an upgrade for the existing standard AimSHOT bore sights that utilize the small LR41 watch batteries. You remove the three watch batteries and the end cap, and replace it with the new end cap that has the attached external battery pack. The kit uses two AAA batteries and will give you over 20 hours of laser battery life.
