AAs are still the most widely sold battery type, used in many toys, radios, flashlights, and remote controls, and in some digital cameras, though more of those are using tiny rechargeables. We tested nonrechargeable lithium, nickel oxhydroxide, and alkaline types.
The longest-lasting was Energizer Advanced lithium. It took 809 photos before dying; the quickest to die, Walgreens Supercell alkaline, took just 133.
Take manufacturer claims with a grain of salt. Duracell Ultra PowerPix, for example, lasted for 174 shots, which is indeed "up to 200 photos," as claimed—but any number under 200 meets that boast.
