Has anyone heard or experienced this?

Nope, but I guess it seems plausible. On my airplane, both batteries have
vents overboard to allow any gases out. I would hope that, even if gas
accumulated in the battery box, an ignition source wouldn't be forthcoming,
but I guess I can't rule that out.

I had it happen in my truck. Battery exploded but evidently kept working but
was leaking acid slowly all over the battery holder and into the cables. Had to
get them all replaced.
