Battery Protector & Sealer 5 Ounces

The Battery Protector & Sealer 5 Ounces by Permatex is an essential maintenance product for any boater or marine enthusiast who wants to extend battery life and prevent corrosion-related failures on the water. This sealant is particularly useful for those who frequently encounter saltwater environments, where battery terminals are prone to corrosion.

The 5-ounce formula creates a protective barrier around battery terminals, posts, and connections, effectively sealing out moisture and corrosive salt air that can accelerate terminal degradation. Its lightweight and easy-to-apply design allows for a durable coat that resists washdown, spray, and vibration, which are common stressors on marine electrical systems.

Anglers and cruising boaters benefit most from this product because saltwater environments accelerate terminal corrosion faster than freshwater use. Applying the Battery Protector & Sealer directly to cleaned and dry battery terminals, posts, and surrounding connection points ensures optimal protection before sea trials or seasonal storage.
