The Boater Sports Battery Terminal Kit from Blue Dog Marine allows quick conversion of a "post" style battery to a "wing nut" style, ideal for marine applications. The kit includes a 5/16" negative terminal and a 3/8" positive terminal, both with color-coded wing nuts for easy identification. Sold in pairs, these terminals ensure secure and reliable connections, simplifying battery maintenance and replacement. The wing nut design offers a user-friendly, efficient solution, eliminating the hassle of traditional battery posts.
