Moeller Battery Boxes & Trays

Moeller Marine Battery Boxes & Trays: Built for the Water

When it comes to protecting your boat's electrical heart, the battery box matters just as much as the battery itself. Moeller Marine has built its reputation as a go-to manufacturer for marine-grade battery containment, engineering battery boxes and trays specifically to handle the punishing conditions of life on the water — salt spray, vibration, fuel vapors, and relentless UV exposure.

Two Manufacturing Approaches, One Goal: Secure Containment

Moeller offers two distinct construction methods across their battery box lineup, each suited to different size and application needs:

• Injection-Molded Boxes — Designed for smaller Group 24, 27, 30, and 31 series batteries, these boxes feature non-corrosive, high-strength plastic construction and come complete with hold-down straps and mounting hardware. Their precise fit and lighter weight make them ideal for runabouts, bass boats, and smaller inboard/outboard applications.
• Roto-Molded Boxes — Built for larger batteries like the 4D and 8D series, Moeller's roto-molded boxes use a thick polyethylene construction that is chemical and rust resistant and will not corrode. These heavy-duty enclosures are the choice for larger vessels that demand serious cranking or deep-cycle reserve power.

Compliance and Safety You Can Count On

Moeller doesn't just build battery boxes — they engineer them to meet real regulatory standards. Their battery boxes are constructed to meet CFR 177.150 standards, and when properly installed, they conform to USCG regulations, which require all marine battery boxes to be securely fastened to the deck with vent openings unobstructed. For boaters who value both safety and peace of mind, that compliance pedigree is significant.

From Trays to Full Enclosures

Not every application needs a full box. Moeller's battery tray lineup — available for Group 24 and Group 27 series batteries — offers a low-profile alternative for installations where vertical space is limited. These trays feature self-locking security knobs and stainless steel hold-down rods, ensuring the battery stays firmly in place even in rough water. Some tray models also include a quick-release buckle and strap for fast, tool-free battery swaps during a long day on the water.

For boaters who want added functionality, Moeller also produces the Power Plant battery box — an upgraded enclosure that features an on-touch LED charge indicator and a built-in 12-volt accessory adapter port with a 10-amp fuse, so you can monitor battery state and power small accessories without additional wiring.

Why Moeller Stands Out

Cheap battery containment is a false economy. Inadequate boxes allow batteries to shift, corrode their terminals, and wear out far sooner than they should. Moeller's marine-grade designs address each of these failure points with purpose-built materials and hardware. With a lineup that spans compact trays for a solo trolling battery all the way up to dual 8D enclosures for twin-engine sportfishers, there's a Moeller solution for virtually every vessel.
