Air and water tight, probably not. Just think how most car batteries (also flooded type) are exposed under the hood. In another application, where flooded batteries are contained in the trunks of cars, they have a special gas collection type cap that connects to a tube, which then vents outside the trunk space to the outside. My guess is that the excess gas released during charge, is meant to vent out that hole you mentioned.

Not going for air and water tight, just sealed at the top so gas does not escape into the coach.

Just finished caulking the riser I added to the step cover.

There are holes at the top and bottom of the battery compartment that are open to the outside. Se pic.

Well it seems like the gas builds up under the step until it finally escapes and sets off the CO detector.

If you look back at the picture of the battery compartment you can see that hole in the back is below the rim that the the step sits on. With the step built up to accommodate the taller batteries it creates a space above the rim.

the vents in the caps of the new battery sit higher than that rim.

I caulked the riser but the gas still escapes into the cabin and sets off the alarm

I love these batteries, need to solve this ventilation problem.

Maybe a rubber or foam gasket on the bottom of that as continuous of a piece as you can get?

Then make sure there is a louvered vent in the box?

I officially gave up on this mod today and installed a group 27 battery.

I didn't like the idea of gas collecting under the step if I completely sealed the compartment.

thought about springing for 6volt AGM batteries but the dealer had none in stock and I am in a pinch for time.

Not certain that the converter would properly handle AGM batteries and I called the distributor too late to reach them.

Will remove the step riser and go back to the stock configuration tomorrow.

May pursue AGM batteries in the future, but for now, a little more stealth camping!!
