I like the ratchet strap idea. Mine are gel, no box, and the crummy plastic CTyre strap.
Does anyone know where to get ratchet straps, in general, with SS hardware ? Batteries, Dingy to dock, float removal and securing, etc. many more applications. Thanks for any guidance.

Seems kinda counter productive to epoxy in a box for leak tightness only to then put holes in it for fasteners. I bent some flat aluminum bar stock so that it follows the contours of the inside of the battery compartment. The bars are held in place at the top of the compartment. My straps are fed perpendicular under the bars and the batteries sit on top of both. The straps wrap across the top of the batteries and meet on the side. The load requirements are side to side movement of less than an inch and mounts which can hold 90lbs.

If water is getting to my compartment then I have serious problems well beyond the batteries. Can you clarify what kind of ratcheting strap you use? I don’t think much of the plastic clamp strap that came with the boat.

In summery it describes keeping the batteries sufficiently mounted to prevent sliding around. It describes a cover to prevent inadvertent contact with the terminals. If you use a ratchet strap and insulated terminal covers then you technically meet the requirements. Commercially available plastic battery boxes provide a means of restraint and insulation of the terminals. Properly made and used, the battery boxes also provide a means of catching acid if it were to leak out. The lids are designed to maintain a loop seal which prevents water from getting in the box should a flooding situation submerge the box. Sea water and batteries is a bad combination which can, not just short out and destroy the battery, but also generate chlorine gas. I don't have commercial battery boxes in either of my battery compartments. The batteries are strapped down. The compartments are glassed in to provide leak resistance. The compartments have wooden lids which prevent inadvertent contact with the terminals. I think you are ok removing the plastic boxes.

I ended up putting a Blue Sea Si-ACR to control charging inside the battery compartment as I could find no other accessible space for it. It is not pretty crowded inside that area with wires, two batteries, and the ACR. The compartment is a solid bottom fiberglass area with a wood top panel for access and a strap that goes through slots on the bottom of the compartment. The batteries are sealed AGM. I am considering removing the two battery boxes that the batteries sit inside of inside the compartment as they seem redundant to me with sealed batteries. I can strap down the batteries instead of strapping down the battery boxes. This will give me a bit more room and flexibility in the compartment. Is there any safety reason I should not do this?
