Camco RV Battery Boxes: Group Size, Venting & Hold-Down Guide

Camco RV Battery Boxes: Group Size, Venting and Hold-Down Guide

A battery box for one Group 24 battery is not the same as a two-battery enclosure, and a hold-down tray does not provide the protection of a covered box. Compare Camco's battery enclosures and mounting accessories by the number of batteries, physical arrangement and ventilation components.

Start with the battery and where it will be installed

One battery

55371 is an externally vented Group 24 enclosure. For a Group 27, 30 or 31 battery, compare the standard lidded 55372 box or the open 55404 hold-down tray.

Two batteries

55370 arranges two Group 24 batteries side by side with an external vent arrangement. The longer 55374 is designed for two GC2 or two Group 24/24M batteries end to end.

Replace mounting hardware

55364 is a woven 39-inch battery-box strap, not a battery box. Compare the existing box's strap path and attachment points before ordering it.

Battery fit comes first: Battery group labels help identify a likely size family, but measure the actual battery case and terminals. Verify lid clearance, battery hold-down and any manufacturer-required ventilation before choosing an enclosure. These accessories do not include a battery or charging system.

Camco part number and fit comparison

Externally vented enclosed models are identified separately from standard lidded boxes and open mounting hardware. A box's ordinary ventilation openings should not be confused with the supplied hose-and-grille system of a ducted enclosure.

Part number Product style Battery application Layout External vent components
55370 Externally vented dual box Two Group 24 Side by side External vent kit
55371 Externally vented single box One Group 24 Single battery External vent kit
55372 Standard lidded battery box One Group 27, 30 or 31 Single battery No external vent kit listed
55374 Double end-to-end battery box Two GC2 (6V) or two Group 24/24M (12V) End to end No external vent kit listed
55404 Open hold-down tray One Group 27, 30 or 31 Open tray Not an enclosed box
55364 Replacement box strap For compatible Camco box Strap only Not applicable

Which two-battery box is the better match?

55370: The side-by-side enclosure is listed for two Group 24 batteries. Its venting components are intended to route gas out of a suitable compartment when installed according to Camco and battery manufacturer instructions. Check the side-by-side footprint and vent-hose routing.

55374: The end-to-end box holds either two 6-volt GC2 batteries or two 12-volt Group 24/24M batteries. Camco lists an interior approximately 21½ inches long, 7⅜ inches wide and 11⅛ inches high. Its package includes two straps and four strap clamps with screws; do not assume it is supplied with the external vent ductwork of 55370.

Standard covered boxes versus a hold-down tray

55371: An enclosed, externally vented option for one Group 24 battery. It provides a vent hose, grille and associated mounting components. The vent outlet needs a suitable route to the outside of the installation space.

55372: A larger standard polypropylene box for a single Group 27, 30 or 31 battery. It has a lift-off lid, woven hold-down strap, foot clamps and screws. It is not the same external hose-and-grille enclosure as 55371.

55404: A heavy-duty open hold-down tray for one Group 27, 30 or 31 battery, with mounting and securing components. The tray itself does not cover battery terminals or provide an enclosed compartment.

55364: The separate 39 × 1½-inch woven replacement strap with attachment hardware. Match the original Camco box and attachment arrangement before selecting it.

Camco battery boxes, trays and straps

Before installation

Measure the overall compartment and the actual battery, including terminal posts and cable bends. Check that the mounting surface can support the secured battery and that the lid, cables and vents will not be pinched. Follow the battery manufacturer's requirements for restraint, ventilation and terminal protection. The suitability of a box for an enclosed location depends on the complete installation, not just the box's description.

To identify other battery case designs, see our Moeller battery boxes and trays guide and Attwood vented battery-box comparison. For protecting the connected electrical circuits, consult the RV battery distribution and fuse reference.

Common questions

Does a Group 24 label guarantee that any Group 24 battery fits?

No. Verify the battery's actual case and terminal dimensions plus required clearances against the exact box's internal dimensions.

Can a standard lidded box replace an externally vented enclosure?

Not automatically. Compare the ventilation requirements of the battery and compartment and use the proper vented arrangement when required.

Is 55374 the same layout as the side-by-side 55370?

No. Both hold two batteries in the listed configurations, but 55374 is a longer end-to-end box, while 55370 uses a side-by-side design with external vent components.

Is 55404 a complete battery enclosure?

No. It is an open battery hold-down tray, not a covered box.
