Uh, I beg to disagree.  Everything I've read indicates that if the device
ever forces more than a few microamps back into the batteries, you must _NOT_
use alkalines, though carbon-zinc's are OK.  The reason for not wanting NiCd's
might be because of the lower operating voltage (1.25V/cell).

Odds are that it is a misprint, but since all the literature from battery
manufacturers says that the alkaline cells can _explode_ if "recharged", I'd
be inclined to stick with the carbon-zinc's.  (Or if you are adventurous,
try some NiCd's.  They'll probably work, and unless stored for many years,
won't leak [I've had a few leak after 15 or so years in a drawer :-(].)
