I think I am screwed.

Sadly, it sure sounds like it.

I had the same thing happen to my 392. Fortunately, I caught it before
permanent damage was done. It still took a lot of cleaning to restore it to
operating condition.

I can have cells sit in things for years and nothing happens, but when one does
leak, it's always in some device that really gets screwed up by it.
