Consumer Reports: best AA batteries

(WMC TV) - Double-A batteries are the biggest sellers.

They are commonly used in flashlights, digital cameras, remote controls, and toys. Consumer Reports tested a dozen, including big names such as Energizer, and store brands such as Walgreens and CVS.

Testers used a rack to evaluate battery performance. It was programmed to mimic a digital camera and a flashlight. The tests turned up big differences.

The Eveready Gold, the worst performer, took only 52 shots before dying.

The Energizer Ultimate lithium, the best in the test, took 682 shots. But it's expensive:  more than $2.50 per battery.

Although lithium batteries cost more, Consumer Reports said they can be worth it for digital cameras and other high-drain devices.

Among alkaline batteries, top ratings went to the Duracell Ultra Power for about $1 per battery. Alkaline batteries don't tend to last as long, so they are better for low-drain devices like flashlights or remotes.

For toys, Consumer Reports said rechargeable batteries are best. Lithium batteries and rechargeable batteries should be recycled. Though many places allow you to throw out alkaline batteries, Consumer Reports said it's better to recycle those, too. You can find a recycling center near you at Earth911.com.
