Uhhhh- - - - -do the math again. Two AA batteries provide 3 volts, not 4.5. (1.5 v. each) You could use a potentiometer to drop the voltage to the CD player, just use one that will flow enough current to supply it. Drop me an IM with your email address, and I can send you a schematic on how to wire the potentiometer. (Never mind- - - -your email is already in my address book!) I'll see if I can draw up a quick circuit diagram and give you some Radio Shack part nunbers.
The battery cell caps are vented, so unless you're doing a high-rate charge like a quick boost, it's not necessary to remove the caps.
