Battery Heat Shield Optima Group 35

The Battery Heat Shield for Optima Group 35 by Heatshield Products is designed to protect your marine electrical system from excessive engine heat and thermal damage. This product is particularly useful for anyone operating a boat or watercraft with an Optima Group 35 battery, as it helps maintain battery performance and prolongs service life.

Constructed from a reflective heat shield material, this protective cover reflects radiant engine heat away from your battery while allowing for essential airflow. Its lightweight design—0.44 pounds—ensures easy installation without sacrificing durability or thermal performance.

This heat shield is ideal for anglers and boaters who depend on their batteries for trolling motors, navigation electronics, and auxiliary systems during extended outings on the water. It fits the footprint of Optima Group 35 batteries precisely, wrapping around the battery case to create a thermal barrier.
