Too late for today, but I'll test with a multi-meter tomorrow. First, I'll have
to ask the kids which NXT it was ... senior moments, y'know.
I grew up with zinc-carbon batteries, which leaked as well but were/are
relatively environmentally safe. Nowadays, with all the exotics (meaning
"toxic" in most cases) the benefits of long-lasting batteries seem to make us
oblivious to the risks. If it wasn't for a knowledge of a little chemistry from
college, I wouldn't have thought twice about the leak. Now, I intend to always
make a point of it in class
As for the QA, I'm almost certain that these NXTs did not get much of a burn-in.
They came in recycled corrugated boxes typical of merchandize headed for low
cost Wal Mart. Two of the 12 shipped were terribly smashed in transit. It was
not very comforting to feel that we seemed to be getting very cheap stuff.
