The RV Lockbox 23" Wide Mouth Battery Box is a heavy-duty aluminum enclosure for housing RV and trailer batteries. The wide-mouth slide-top design provides easy access to the batteries for maintenance, watering, and terminal connections without awkward reaching into a narrow opening. The 21.5" × 9.75" interior top opening accommodates two Group 24 deep cycle batteries side by side, or similar-sized batteries including some 6V configurations.
The smooth aluminum construction with a powder-coated semi-gloss black finish provides a clean, corrosion-resistant exterior suited for long-term outdoor trailer use. Three pre-punched knockout holes with an included grommet make routing battery cables clean and simple — no drilling required. Self-tapping mounting screws are included for securing the box to the trailer.

Key dimensions to check: Outside (box footprint): 23" L × 11.25" W × 10.875" H Inside opening (top): 21.5" L × 9.75" W × 10" H Also verify your batteries fit the interior dimensions — Group 24 batteries are typically approximately 10.25" L × 6.8" W × 8.9" H, but dimensions vary by manufacturer.
Knockout holes: Three pre-punched holes are provided for routing battery cables. Use the included grommet to protect cables from the aluminum edge. Mounting: Self-tapping screws are included for securing the box to the trailer frame or mounting surface. Waterproofing: This box is not waterproof. If your installation location is exposed to standing water or sustained rain, additional weatherproofing measures may be needed around cable entry points.
