CURT 52022 Lockable Trailer Battery Case
The CURT 52022 is a compact, lockable battery case designed to shield a trailer battery and charger from the elements and corrosion. It fits the CURT breakaway battery #52023 and features a lid that accepts a padlock for added security. This box is best for users who need a tight, weatherproof enclosure in a smaller footprint. It is especially suitable for owners prioritizing security and protection in exposed trailer setups. A potential limitation is its tighter internal space, which may limit larger or non-standard batteries.
Camco Large Battery Box 55373
The Camco 55373 offers a roomy interior designed to safely store Group 27, 30, and 31 batteries for RVs and other large setups. It arrives with a hold-down strap, foot clamps, and hardware for secure mounting. This option is best for larger batteries or when you need a robust, ready-to-install enclosure. A caveat is its larger footprint, which may not suit compact trailers or tight storage spaces.
VEVOR Trailer Tongue Box, 36″ x 12″ x 12″
The VEVOR tongue box provides a large 36 × 12 × 12 inch storage space designed to organize batteries, tools, and outdoor gear. It uses carbon steel for durability while keeping weight manageable. It’s best for users who want a single, spacious, weather-resistant storage solution for tools and batteries on flat trailers or RVs. A limitation is that it may require more installation space and mounting hardware than smaller boxes.
NOCO Snap-Top BG27 Battery Box
The NOCO Snap-Top BG27 is designed around Group 27 batteries and a rugged snap-top style that simplifies installation. It features pre-drilled internal pilot holes for mounting and an updated strap-mount system for more demanding installs. This box is best for users seeking straightforward mounting and versatile compatibility with several battery types, including automotive and marine. A potential downside is its emphasis on Group 27 sizing, which may not fit all battery configurations without checking dimensions.
Attwood Group 24 Vented Marine Battery Box
The Attwood Group 24 vented battery box is built for marine and outdoor use with a design that supports Group 24 batteries up to 10.125 inches tall. It uses acid-resistant polypropylene and includes a ventilation system to release gases safely while minimizing water intrusion. This option is best for boat trailers and harsh outdoor environments where safe venting and chemical resistance are priorities. A limitation is that vented boxes may require regular maintenance to ensure the vent remains unobstructed.
Buying Guide
What should you consider when choosing a cargo trailer battery box?
Battery box size must fit your battery type and the available space on your trailer. Consider interior dimensions, mounting options, and whether you need a lockable lid for security. Materials should resist corrosion, temperature swings, and moisture. Look for venting for lead-acid or flooded batteries and compatibility with common battery groups (e.g., Group 24, 27, 31).
What features add protection and ease of use?
- Lockable lids or padlock compatibility add security against theft.
- Ventilation reduces gas buildup for vented batteries and improves safety.
- Pre-drilled mounting holes and strap mounting systems simplify installation.
- Durable materials like heavy-duty plastic or carbon steel balance weight and durability.
How do you balance space, weight, and accessibility?
Choose a box that fits your largest battery with room for wiring and venting. A larger interior helps with Group 27 or 31 batteries, but may require more trailer space. Heavier boxes add weight to the trailer; ensure your tongue weight and payload capabilities are considered.
What are practical installation considerations?
- Mounting location should be accessible for cable routing and venting.
- Ensure the chosen box can be securely fastened to trailer frame or floor.
- Check that the lid seals effectively against water and dust in your typical environment.
