I had the same problem, but I found out about the leaking when I was
wintering the engine. I did not notice any wetness in the bilge, but when
I was finished I noticed my jeans were falling apart. The acid ate through
the seat and legs from when I sat next to the battery. The dealer could
not identify the problem, so I just purchased a battery box, with a lid, so
the acid would not splash around the bilge. The battery lasted 3 yrs, and
it never failed me, but when the tire dealer put a heavy stress on the
battery it showed up weak. Since I didn't want to have it fail me in the
middle of the lake, I replaced both of them.

Sorry to hear that you have a bad experience with a leaky battery. But
I think neither of mine is leaking. I didn't smell anything unusual.
They were just water. I used my bare hands with paper towel to clean
the battery trays, and my skin was not irritated.
