Our CNC machined aluminum battery mount is designed around the optima battery. It is a simple, strong, and good looking way to hold your Optima battery anywhere. The entire battery mount is machined from 6061 billet aluminum. Three countersunk stainless steel bolts secure the top of the battery mount to the support rods. The base of the mount is mounted to your vehicle with no visible bolts from the top. There are 6 drilled and tapped holes on the underside of the base. Although fewer attachment locations will securely mount your battery, we provide 6 mounting holes to give you added flexibility. We provide a mounting hole template that will assist you in locating the holes. The mounts are shipped in a natural aluminum finish. The dimensions of the battery mount are 11 1/2" X 8 1/2" X 7 1/2" tall.
