Off the topic of labellers, the old CB walkie talkies used to have a dummy
cell which replaced 2 AA cells. If you used rechargables, you use 10
batteries. For alkalines, you use 8 batteries, and a dummy insert.

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...
