Wet cells definitely can emit corrosive acid fumes. My wife's car battery does this, it gets the nasty sulfur-metal-acid crystals all over the battery connections. I solved that by spraying them with engine fogging oil.
You have some form-factor issues with wet vs. gel/AGM. A wet cell needs to be in a battery container that can hold spilled acid. A gel/AGM cannot leak and you could even cut it in half and use the half that still had the terminals. The 35 MK I can fit a 4D into the battery space, but not a 4D in a container, so if you want to go that way a wet battery is out. We once did have a wet battery not in a case and it cracked in half during a hurricane and leaked acid into the bilge. That was not a nice smell - sulfur and chlorine gas :( Speaking of battery size, "golf cart" is not always a wet cell. You can get them in gel and AGM too. Two golf carts are a LOT easier to move around than one 8D and the AHs are about the same. You also can fit 3 group 24s in an 8D case.

Dwight, I think the theory is that the same electroisys that is breaking the molecular bond in the water is breaking the bonds in the sufuric acid resulting in corrosive sulfer gas.

No noxious gases to be vented into the cabin. I have a lot of corrosion on my electrical panel that I directly attribute to being bathed in off-gassing from old batteries. Plus, they're safer from an explosion perspective, as well as if you ever end up inverted for a short period of time.

Listers, As you know, I'm redoing the electrical systems on the Enterprise (thanks to all for diagrams and advice). So now comes the question of what type of battery to use in my house bank - Flooded, Sealed or AGM? What do you have on your C&C and why do you prefer it? And, if you have flooded, how often do you top them off with distilled water? The countdown has begun! http://enterpriseb.blogspot.com/2015/02/launch-of-enterprise-countdown.html All the best, Edd Edd M.
