Parts Desk Insights
The 90651 vented box is the correct choice for flooded lead-acid (wet cell) batteries in Group 24 or 24M size — these batteries off-gas hydrogen during charging, and a vented enclosure is required for safe installation. The four enlarged cable openings make wiring cleaner and easier, particularly on boats where battery cables are thick or the box is installed in a tight compartment. If you’re installing a sealed AGM or gel battery in Group 24/24M size, a non-vented box is more appropriate — see the Attwood 90691 Non-Vented Battery Box for Group 24/24M. For Group 27M batteries, see the Attwood 90671 Power Guard Vented Battery Box for Group 27M. For Group 29/31 batteries, see the Attwood 90841 Large Vented Battery Box for Group 29/31.
