It comes with a lift-off lid, a woven hold-down strap, foot clamps, and stainless steel screws, and it meets USCG and ABYC standards. Perfect for RV house banks, marine deep-cycles, and trolling motor batteries.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eA battery that isn't tied down is a hazard, plain and simple. The Camco 55372 Large Battery Box handles that job the right way. It's a black polypropylene case built to hold and protect a single Group 27, 30, or 31 battery, whether that's the house bank in your RV, a deep-cycle on your boat, or the battery running your trolling motor. Drop the battery in, snug the strap, set the lid on top, and you're done.\u003c\/p\u003e\n\u003cp\u003eWhy does a box even matter? Two reasons. First, an unsecured battery is a projectile. Hit a wave or a pothole and 40-plus pounds of lead can shift, crack a case, or snap a terminal. Second, an exposed top post is one dropped wrench away from a dead short. The lid and strap together solve both. It's cheap insurance for an expensive battery and everything wired to it.\u003c\/p\u003e\n\u003cp\u003eFit is the first thing to check, so here are the numbers. Inside, the box measures 7-1\/4 inches wide by 13-1\/4 inches long by 8-5\/8 inches tall, with an extra 2 inches of head room above that for your terminals and cable lugs. That's the room most Group 27, 30, and 31 batteries need to sit flat and still clear the lid. Measure your battery before you order. Group sizes are a general guide, and a tall dual-purpose case can run close on height, so terminal clearance matters more than folks expect.\u003c\/p\u003e\n\u003cp\u003eThe case is molded from corrosion-resistant polypropylene, which is exactly what you want sitting under a battery. Batteries vent, they weep a little acid over the years, and they live in wet, salty, vibrating places. A plastic box shrugs that off where a metal tray would rust through. It's lightweight too, so it won't add meaningful weight to a boat or trailer that's already loaded down.\u003c\/p\u003e\n\u003cp\u003eEverything you need to mount it comes in the box. You get the lift-off lid, a durable woven hold-down strap, foot clamps, and stainless steel screws. The foot clamps screw down to your deck, bulkhead, or trailer frame and lock the base in place. The strap runs up and over the lid to keep the battery from bouncing out on a rough road or a choppy day. Stainless hardware means the fasteners won't be the first thing to corrode.\u003c\/p\u003e\n\u003cp\u003eHere's the part that matters if you're rigging a boat. This box meets USCG CFR 183.420 and ABYC E-010.7, the two specs a surveyor or the Coast Guard will look for on a battery installation. If you're wiring a boat to be compliant, or you just want the job done to the standard the pros use, a rated box like this is the easy way to get there. The lid also keeps stray metal, tools, and dropped fittings off the terminals, which is real fire prevention, not just a nice-to-have.\u003c\/p\u003e\n\u003cp\u003eInstallation is straightforward. Pick a spot with some airflow, mount the foot clamps, set the battery in, run your cables, and cinch the strap. It works just as well in a truck bed, a camper, a utility trailer, or a small boat. One thing it won't do is hold two batteries or an oversized 4D or 8D case. This is a single-battery box sized for Group 27 through 31. If your bank is bigger than that, you'll want a larger enclosure. But for the vast majority of RV house batteries and marine deep-cycles, this is the right size at the right price.\u003c\/p\u003e\n\u003cp\u003eKeep an eye on it over the seasons. Give the case a wipe if the battery ever weeps, check the strap tension after the first few trips, and make sure the foot clamps stayed tight through a season of vibration. That's about all the upkeep a box like this ever asks for, and it'll outlast several batteries if you treat it right.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003eFits Group 27, 30, and 31 batteries, covering most RV house and marine deep-cycle sizes\u003c\/li\u003e\n  \u003cli\u003eMolded from corrosion-resistant polypropylene that shrugs off battery acid, salt, and vibration\u003c\/li\u003e\n  \u003cli\u003eMeets USCG CFR 183.420 and ABYC E-010.7 for compliant marine battery installs\u003c\/li\u003e\n  \u003cli\u003eLift-off lid shields the terminals from dropped tools and stray metal\u003c\/li\u003e\n  \u003cli\u003eDurable woven hold-down strap keeps the battery seated on rough roads and choppy water\u003c\/li\u003e\n  \u003cli\u003eFoot clamps and stainless steel screws included for a solid deck or frame mount\u003c\/li\u003e\n  \u003cli\u003eInside dimensions 7-1\/4 in.
