Pete, The battery box can serve two purposes – prevent a spill and cover the terminals. As far as I know, the AGMs don’t have to be in a box to protect you from spills, but you have to cover the terminals in some way to prevent a short (a box is one of the many ways).
Btw. they are lead-acid, but non-spillable (and generally, not venting). If you are adding AGMs, mixing them with normal L-A batteries is not a good idea as charging voltages should be different. Btw. consult some charging/maintenance guidelines for AGMs (e.g. Maine Sails articles on that). AGMs are great batteries but they are much more prone to being murdered by their users.

I would like to add a couple more batteries and am looking at AGMs due to their tolerance of being at an angle. Since, as I understand, they are not technically a lead-acid, do they still need to be installed in a battery box? I’m very tight on space and could use the extra few inches. Thanks, Pete
