Picky, picky, picky. :-)  There are various wet-cell chemistries around,
most of them with fairly specialized uses only.  (For example, there's one
that uses plain salt water as the electrolyte.  Its performance is not
impressive, but it's used anyway for some portable military applications,
where it's useful that it doesn't spray corrosive chemicals around if it
gets a hole shot in it.)  I was being picturesque rather than precise,
always a mistake on Usenet... :-)

I do, but I don't always tell all of it. :-) :-) :-)
