If you are referring to calculator/watch batteries, I do use them in my
bots... but primarily in the solar bots. I usually place a home-made
socket for them right underneath the solar cell, so I can really fire the
little buggers up when people want to see what they do. (Most mere mortals
don't seem to want to spend time-lapse quantities of time waiting to grok
the overall behavior of the bot. Sheesh.) The only problem is that I can
easily drain a $5 battery in a few minutes, some last tens of minutes, but
not too long. Expensive hobby.
The Duracell internal cells are a bit heavier, a bit more visually
obtrusive, but they sure last a long time.
