Walmart has a 4 pack of LiFePO4 AA batteries for $10. (They're Westinghouse 400mAh, 3.2v.) Since they're 3.2v, they're only usable in devices that take two or more batteries. (Make jumpers out of scrap metal or copper tubing.) They should work excellent for remote controls and similar stuff.

I'm actually going to get an adapter that converts two of those AAs into a 9v for my multimeter. (The DSP in that meter eats batteries almost as fast as Jean Ma eats potato chips... Those Lithiums should give me twice the runtime of a 9v, plus there's much less charge loss when not in use. And two of those AAs are cheaper than a NiMH 9v.)
