If you're going to standardize, AAs are my top choice for that reason. If a store carries any kind of batteries at all, they'll carry AAs. The low self-discharge NiMH batteries, like Sanyo Eneloops, are excellent without a doubt, and I use them. But I didn't want to invest in buying and maintaining a bunch of them for emergency use.
