RL The problem with making comparisons is that the power you can get out
RL of most types of primary (non-rechargeable) cells depends heavily on a
RL lot of factors, such as:

RL -- Current drain
RL -- Duty cycle
RL -- Temperature
RL -- End voltage

There is another factor I've discovered for a cell's usage in audio
applications such as a battery powered portable mixer or especially an
electret microphone. Alkaline cells seem to be plagued with pops and
ticks while carbon cells are dead quiet in comparison. Since most
electret mics have very simple electronics with no voltage regulation,
the battery must be extremely quiet. Unfortunately I don't have the
numbers on hand to document my experience but this is just to comment
that sometimes there are other factors (noise) which may make a cell
type more desirable for very specific applications. For example
electric guitar players are sticklers for the type of square 9 volt
batteries that go into their vintage pedals.
