Well boats usually do not blow up or catch fire from hydorgen leaking
from batteries. It is usually from gasoline vapors or leaking propane. The
plastic battery box is a corrosion / spill containment issue.
My Jaguar XJ8 L has the battery in the well sealed trunk of the vehicle, I have
also owned several cars that the batteries were under the back seat. So
Hydrogen gas and venting is a real issue but statically incidents are pretty
low from what I can tell
Like I said earlier there are repeaters in the same block house that mine is in
and they place the batteries in the bottom of the cabinet with no real venting
taking place, does not seem to be an issues and as most of the chargers are
slow charge with trickle so not a lot of gas released anyway. You add to this
that hydrogen rises very quickly as it is much lighter than air and you ask the
question how much gas would stay in an enclosed area ? My guess is little to
none.

Thanks to everyone for the feedback so far!
So here is what is bothering me this afternoon. Maybe someone here can shed
some light on this for me.
The battery I am thinking about using was one I bought a while ago for my boat,
but I didn't use it because it was too big for the battery box in the boat
(don't ask). I kept it knowing full well I had other uses for it.
Thinking about this some more, by law any wet cell battery on a boat must be
contained in a battery box. Thinking more about this, I realize that the
standard plastic battery box is not really vented, nor completely sealed. In
the case of my boat (24' pontoon)has two such batteries, one under the seat in
the rear for the motor and the other under the seat in the front for the
trolling motor. The compartments under the seats are enclosures in and of
themselves. The rear one is charging off the engine during run time. On an
afternoon cruise it could run for several hours charging the battery the whole
time.
So the wet cell battery, in the box by law, is charging in a box with little
ventalation. Are boat owners everywhere sitting on ticking hydrogen bombs?
