Green crud usually means copper oxide. Sounds like the
battery container was corroding. Could be due to leaked
chemicals from the inside, but could be also caused by
moisture.
But don't lithium batteries contain just
lithium, which is all gone
by the time the battery discharges? An alkaline or carbon-zinc
battery starts oozing as a rule within a few years. The AAA lithium
battery presumably doesn't run the risk of that until at least 2020.
No. A battery with just one metal (or even no electrolyte) wouldn't
work too well.
As proof, I pulled a CR2032 out of a machine today, and it had some
green crust forming on the battery. The batteries were in machines
that were about 10 years old.
