Excessive engine bay heat ranks among the leading causes of premature battery failure, especially in vehicles running turbochargers, superchargers, or other power adders that push underhood temperatures to extremes. The Heatshield Products Lava Battery Shield wraps the battery in a custom-fit enclosure built from naturally acid-resistant volcanic rock fiber, blocking radiant heat before it degrades battery chemistry and shortens service life.
Volcanic rock fiber construction. Unlike traditional reflective foil shields, Lava material is naturally resistant to battery acid and handles continuous exposure up to 1200°F, with intermittent spikes up to 2000°F. The material outlasts conventional reflective heat shielding, making it a long-term solution rather than a stopgap.
Custom-fit design for a clean install. Each shield is sized to match specific battery groups, including Optima 35, Group 34/78, Group 65, Group 94R, Group 49/H8, Group 75, and several others. The close fit means no trimming, no improvising, and a finished appearance under the hood. Installation takes minutes with no special tools.
Compatible with all battery chemistries. The shield works with lead-acid, AGM, gel, and lithium batteries, so it fits daily drivers, street builds, and dedicated track cars equally well.
