Hi,

What are the most economical batteries to use in devices that are
rarely used, such as a label maker (e.g. 15 labels a year). I've
gathered over the years that in items like flashlights it pays to use
better brands, but what about the situation above? Are rechargables a
good idea for that?

The new rechargeables that keep their charge like regular alkalines
(long shelf life, unlike ordinary rechargeables), would be a good
idea. Hybrio is one brand, there are several now.
Sorry that I am comming into this thread so late....BUT I am a
Backyard astronomer who uses a Goto computerized Scope that can be
powered by AA Batteries...

According to those in the know (not me) RECHARGABLES just do not
work...

The claim is that 8 rechargable AA's only put out a total of 9.6 v not
when freshly charge not the 12 V that the regular AA's put out... so
while the rechargables will work for 10 minutes when the voltage even
drops a hair all hell breaks loose because the scope dances all over
the sky ... instead of slewing to Jupiter or some specific target...

Not that it makes any difference because everyone runs off a 12 V Gel
cell battery or regulated power supply anyway... BUT is it really true
that a rechargable AA does not puty out a full 1.5 V when freshly
charged...
