A.A Battery Tray for Group 29/31 Batteries with Strap — Heavy-Duty Polypropylene, Marine & RV Safe

A.A's heavy-duty battery tray securely holds Group 29/31 (and compatible Group 24/27/29) batteries with an integrated safety strap and ten mounting points for automotive, marine, boat, and RV use.

Replace flimsy battery hold-downs with a purpose-built tray designed to resist impact, vibration and the elements. Molded from high-impact, heavy polypropylene, this tray organizes and secures your battery while providing a corrosion-resistant base that fits common Group 29/31-sized batteries. The included safety strap and buckle limit movement during travel or rough water, and ten reinforced mounting points make installation flexible and stable in tight or irregular compartments.

How does this tray keep a Group 29/31 battery from shifting?

The tray cradles the battery in a raised, form-stable pocket while the included strap wraps across the top and locks into a quick-release buckle. The combination of a molded seat and positive strap tension reduces both lateral and vertical movement during acceleration, braking, or wave action.

• Molded polypropylene pocket matches Group 29/31 footprints for snug fit
• Included safety strap with buckle prevents lift and slide
• Raised edges and ribs resist lateral movement
• Non-corroding material avoids metal fatigue and rust

Will it survive marine and RV environments?

Yes — the tray is made from heavy, high-impact polypropylene that withstands UV exposure, salt spray, and road vibration better than untreated plastics or metal bases. Its non-metal construction prevents rust-related failures and reduces long-term maintenance in harsh conditions.

• Heavy polypropylene resists UV and salt corrosion
• Impact-resistant structure tolerates vibration and shock
• Plastic construction eliminates rust-prone contact points
• Easy to clean and drain in damp environments

How easy is installation and what mounting options are available?

Installation is straightforward: place the tray in the compartment, position the battery into the molded seat, run the strap over the battery and latch the buckle. Ten mounting holes (five along each long side) let you secure the tray in multiple orientations to match floor ribs, stringers, or vehicle frames.

• Ten reinforced mounting points for flexible attachment patterns
• Fits flat or slightly contoured surfaces with multiple screw locations
• Quick-release strap speeds battery removal for service
• Works with common hardware (bolts, screws, or marine fasteners)

What battery sizes and vehicle types is this tray compatible with?

Designed primarily for Group 29 and Group 31 batteries, this tray also supports many Group 24 and 27 batteries that share similar footprints. It’s suitable for automotive projects, marine boats, RVs, campers, and utility vehicles where a sturdy, corrosion-resistant battery mount is required.

• Primary fit: Group 29 and Group 31 batteries
• Compatible with many Group 24 and 27 batteries of similar dimensions
• Ideal for cars, trucks, boats, RVs, and off-road vehicles
• Better choice where salt, moisture, or vibration are concerns

Who this is for: Installers, boat owners, RV enthusiasts, mechanics and DIYers who need a reliable, low-maintenance battery mounting solution will benefit from A.A's heavy-duty tray. If you want a non-corroding base that keeps Group 29/31 batteries secure under high vibration or marine conditions and offers flexible mounting options, this tray provides a durable, service-friendly upgrade over basic hold-downs.
