Attwood 9067-1 Vented Battery Box
The Attwood 9067-1 is designed to hold larger Group 27 batteries, with interior dimensions of 13.06 x 6.9 x 10.5 inches. It uses acid-resistant polypropylene suitable for marine and RV environments, and features an integrated venting system to safely release gases while helping prevent water intrusion. This model is best for RV owners who need venting for safety and a snug fit for taller batteries. Practical caution: ensure the mounting strap and base clearance fit your specific RV compartment to avoid interference with other equipment.
Attwood Group 24 Vented Battery Box
Designed for standard Group 24 batteries, this box measures about 10.6 x 7 x 10.125 inches and uses acid-resistant polypropylene with a safety vented design. It’s best for RV setups that require effective gas venting and a precise, compact footprint. A potential limitation is that the venting kit is integral; ensure it remains accessible during installation and maintenance.
Camco Large Battery Box with Straps (55373)
This Camco large box is suitable for Group 27, 30, and 31 batteries. It includes a lift-off lid, durable strap, foot clamps, and stainless steel screws. The box is lightweight yet heavy-duty, made from corrosion-resistant polypropylene. Best for RVs needing a robust, all-in-one storage solution with included securing hardware. Choose this if you want an all-in-one installation with mounting accessories; caution: verify that the product’s internal dimensions fit your exact battery model.
Camco Double Battery Box (55375)
This dual-box solution stores two batteries, such as two 6V GC2s or two 12V Group 24/24M batteries, in a compact footprint of 21.5 x 7.38 x 11.19 inches. Built from heavy-duty, corrosion-resilient polymer, it provides solid protection and organization for larger RV electrical systems. Best for RVs that require separate or two-battery configurations in one enclosure. Limitation: larger overall size may not fit smaller compartments without rearranging other equipment.
Attwood 9069-1 Standard Non-Vented Battery Box
The 9069-1 is a non-vented option designed for Group 24 batteries in OEM-approved enclosed compartments. It features a protective non-vented lid to shield terminals from moisture and debris. Best for RV installations with designated sealed battery compartments. A note: venting is not included, so use only where venting is not required or as specified by the OEM compartment guidelines.
Buying Guide
Key considerations when selecting an RV battery box or cover
- Battery size compatibility: Confirm your battery group and dimensions before choosing a box. Larger Group 27 units need taller boxes; smaller Group 24 batteries fit more compact enclosures.
- Ventilation needs: If your installation requires gas venting for safety, choose vented boxes. If the compartment is sealed per OEM guidance, non-vented designs are appropriate.
- Material durability: Look for acid-resistant polypropylene that withstands wide temperatures and outdoor exposure. This reduces long-term damage from battery acids and weather.
- Included hardware: Some boxes come with lids, straps, clamps, and screws. For quick installs, a kit with mounting hardware saves time.
- Mounting space: Measure the available space in your RV compartment to ensure the box fits without interfering with other components (fuses, lines, access doors).
- Maintenance access: Consider how easy it is to inspect, vent, and replace batteries without disassembling other components.
Practical tips for choosing the best box
- Better for vented needs: If you require fast gas relief, prioritize vented designs with a clear path for fumes.
- Choose this if you need dual batteries: A double box is convenient for two batteries in a single enclosure with built-in stability.
- Avoid this if: Your RV compartment is very tight and cannot accommodate taller boxes or latching hardware.
