We use plywood boxes with sloped top as well, I like the sloped top not only to help migrate the gasses but also because of the fact that a flat surface usually collects stuff! We use soffit vents at the bottom of the box and Zephyr vents to evacuate the enclosure but if the vent fails all there

I am a firm believer in visual inspection the battery bank prior to opening the top weather there is an issue or just looking. We use plywood boxes, sloping top, caulked top frame, top is ¼” Plexiglas / edged with flat edged aluminum storm window frame to provide stability to screw down on

Fellow wrenches, Most CO sensors will be sensitive to both hydrogen sulfide and to hydrogen. Here's a link to a typical sensor . While the unintended sensitivity to hydrogen and hydrogen sulfide may cause false alarms to CO, does anyone know if these de

Rich, I have found that having the CO detector anywhere nearby seems to pick up the battery gasses. I had a problem with one customer's battery box (built by their carpenter) made of pine boards tightly fitted together. It was leaking gasses thru the crack between the boards on the top nea

I would think that locating a CO detector on the ceiling of the room with the battery bank would be enough to do it. You just would not know if it was the battery bank or CO from another source. Your (or their) nose can do that part of the job! Bob Ellison From: re-wrenches-boun...@lists.r
