Moeller Marine Battery Boxes & Trays: Group Size and Hold-Down Guide

A marine battery enclosure should fit the battery itself and the available mounting space. Moeller offers lidded boxes, open trays with stainless hold-down rods and shallow trays with quick-release straps. This guide compares exact part numbers and their published maximum battery dimensions.

Choose an enclosure and restraint style

Covered battery box

Houses the battery within a lidded case. Confirm case size, terminals, cable routing and strap arrangement.

Hold-down rod tray

Open tray with vertical stainless rods and securing knobs. Different MPNs have different battery size limits.

Strap-style tray

Shallow base using a quick-release buckle and strap. Not interchangeable with rod hardware without checking installation.

Moeller enclosed battery boxes

Compare both the external footprint and the maximum battery size. All values below are in inches and represent published specifications for the stated MPN.

Moeller open battery trays: rod versus strap

Rod and strap trays are separate designs, even when they serve the same Group 24 or Group 27 battery size.

MPN Battery group Unpacked outer L × W × H (in) Max battery L × W × H (in) Restraint
042215 Group 24 12.88 × 7.38 × 9.00 10.25 × 6.75 × 8.12 Stainless hold-down rods; knobs
042232 Group 27 14.38 × 7.13 × 10.50 11.75 × 6.75 × 7.75 Stainless hold-down rods; knobs
042216 Group 29 & 31 15.50 × 8.00 × 10.50 13.00 × 7.43 × 10.00 Stainless hold-down rods; knobs
042233 Group 24 11.31 × 7.25 × 1.31 10.25 × 6.75 × 8.12 Quick-release buckle and strap
042234 Group 27 12.94 × 7.25 × 1.31 11.75 × 6.75 × 7.75 Quick-release buckle and strap

For 042234, the tray measurements and strap-style construction are cross-checked against published model-specific supplier data; verify any installation where clearance is critical.

Fit and installation checklist

First confirm the battery case size, including any handles or protrusions, against the manufacturer's battery-size limit. Then check the exterior tray or box dimensions for the mounting area, cable routing, access to battery terminals and any clearances required by the battery manufacturer. Battery chemistry and vessel electrical arrangements may call for particular containment or ventilation.

Group number is only the starting point

The 042213 Group 24 box allows a larger published battery case than the 042215 Group 24 tray. Always check the maximum case dimensions for the specific MPN.
