Our Battery Wrap Kit uses a combination of materials to provide the ultimate in protection from heat and vibration that destroys batteries. An 8" x 12" black felt base pad and an 8" x 40" black felt inner wrap are treated with a proprietary solution to neutralize battery acid. An 8" x 40" adhesive backed outer wrap protects the battery from conductive and radiant heat. The highly reflective surface material is capable of withstanding radiant temperatures in excess of 2000° F.
