Perhaps it used a Li-ion bat with the exact same mAh and voltage as the AAs but needed 2 amps, lasting for half an hour.....THAT's why the AAs may not deliver enough power, not just because of the mAh and voltage ratings.
(I'm making up the numbers, I have no idea how much current a typical AA can deliver, just saying not all battery types are equal. Also note that AA represents a size, not a chemistry or other power requirements. Someone could make a Li-ion AA, or AAA or AAAA I suppose.)
On the other hand, I agree that more standardization among battery sizes (and screws, and connectors) would make for a better world.
Or else, it would be neat if the standard was to to tell the on-demand battery manufacturing machine what power requirements, dimentions and connector type you needed, and it just made you a battery, like making a cookie out of dough.....

I was thinking of Lithium-Ion (Li-Ion) AA or AAA batteries, mainly since the AA and AAA sizes are an already-existing standard. Considering how much power a small-and-thin Li-Ion battery can contain, how much more power would a AA or AAA Li-Ion battery contain? Plus, it would allow the use of Alkaline and Carbon batteries (that you can buy anywhere) as a short-term emergency backup if needed.
