T-H Marine Optima Battery Tray Holder for D27M and D31M – Rugged UV and Corrosion Resistant Marine Battery Tray with Poly Strap, Stainless Buckle, 8 Mounting Slots, 13" x 7"

The T-H Marine Optima battery tray holder is purpose-built to fit the unique case shape of D27M and D31M series marine batteries. Instead of forcing a rounded case into a generic rectangular tray, this design provides a secure footprint that supports the battery properly in boats, RVs, and camper installations. With a base that measures approximately 13 inches long and 7 inches wide, it is sized to match common D27M and D31M footprints while minimizing wasted space in crowded compartments. The tray is molded from rugged poly material that is resistant to UV exposure and corrosion, making it well suited for use in bilges, deck lockers, and exterior storage. An array of eight mounting slots built into the base gives installers flexibility when positioning fasteners, allowing solid attachment even when structure or stringers are not perfectly aligned with a fixed pattern. Once the tray is mounted, the included poly strap and stainless steel buckle secure the battery in place, helping prevent movement during rough water runs, highway towing, or off-road travel. Designed to stand up to the typical chemical environment around batteries and engines, the tray and hardware are resistant to gasoline, oil, acid, and most common compartment chemicals. This durability supports long service life and continued battery security over time. For owners running premium D27M or D31M batteries in their boat or RV, this tray provides a dedicated mounting solution that protects a high-value power source and keeps installations tidy, secure, and compliant with good rigging practice.
