Expect 1/2 to 1/3 less usable live from a set of AAA versus AA.
Only reason they specify AAA is it makes the product smaller
versus if you had to use AA. They (AAA) are OK for use in
TV remote controls, but you'll be changing AAA cells every
other day in a radio product application. My rule is if it uses
AAA then I don't buy it. My neighbor bought a pair of FRS
radios that used AAA cells and took it camping. Of course the
kids had fun seeing how far they could talk around the campground
but he also said the batteries were exhausted after just 2 days.

What are the tradeoffs when buying
radio gear that is powered by AAs
vs. AAAs batteries?

Both AAs and AAAs seem to be priced the
same.

I have never bought a radio using AAAs,
but now I am very interest in buying a
Sony pocket radio that uses AAAs, so
I am thinking of making an exception
to my rule of never buying gear that
uses AAAs.
