These Battery Terminal Covers are specifically engineered to insulate integral marine wing nut terminals, thereby safeguarding battery cables against corrosion and short circuits. They comply with USCG and ABYC standards aimed at preventing accidental grounding of battery terminals. The covers are color-coded to prevent any misidentification of polarity. They are compatible with the majority of marine batteries, as well as automotive batteries equipped with additional marine terminals. The construction utilizes injection molded PVC for enhanced durability.
