Americans burn through several million batteries each year. AA batteries are the most popular. Just in time for the holidays, Consumer Reports' test results are in on which ones last the longest.

They tested a dozen batteries, including big name and store brands.

Testers used a rack programmed to mimic a digital camera and a flashlight.

The Eveready Gold, which were the worst batteries, took only 52 shots with the camera before dying.

The Energizer Ultimate Lithium, the best batteries, took 682 shots. But they are more expensive, at more than $2.50 per battery.

Among the alkaline batteries, top ratings went to the Duracell Ultra Power, which cost about $1 a battery.
