Loren, this radio does not have aaa batteries but an internal rechaegeable..
I, like you, have been on a quest to find the same type of radio you seek, but i have yet to come across one, perhaps one but it looked cheapo and crappy. I emailed CCrane once to make sure that radio above has annexternal speaker which i think it does, but they never returned my email.
Considering that Black Diamond now has their headlamp ReVolt which by itself can charge aaa batteries, i saw this as an opportunity to find a radio with mp3, am, fm with aaa and thus have no need for extra charger for AA
Its really hard to find any radio (with external speaker) and am fm that takes aaa IME
By the way, for what its worth to anyone, do not ever buy the Grundig radio REI sells. It takes aaa, but the stations creap on you up or down, making it insanely aggrevating, if not worthless.
