Consumer Reports tests AA batteries

Consumer Reports

Batteries that go the distance
In happy times (taking holiday photos) and sad (enduring winter storms), you want a battery you can trust.

We hired a lab to run new, improved tests that mimic the main uses of AA batteries: to power digital cameras and flashlights. We tested 10 alkaline and two lithium batteries. Neither type is rechargeable. (In past tests, we’ve found that rechargeables of 2,350 milliamp-hours or more are best for often-used toys like game controllers.)


In cameras.

This test mimics everyday use, zooming, flashing, shooting, and resting until batteries die. Energizer Ultimate lithium took 682 shots in our tough test; Eveready Gold alkaline, just 52.

In flashlights.

This test involves the equivalent of turning on a flashlight for 4 minutes every hour for 8 hours, letting it sit for 16 hours, and repeating the cycle until batteries die.

Battery life ranged from about 7.5 hours, for the Energizer Ultimate lithium, down to about 5.2, for the Eveready Gold alkaline. The best alkaline, Duracell Ultra Power, lasted about 6.7 hours.

Bottom line.

Energizer Ultimate lithium lasted longest in both tests. Lithiums are good in high-drain devices like cameras. Alkalines have shorter lives but cost less, and some perform almost as well in low-drain devices like flashlights and remotes.

Most alkalines have a shelf life of about seven years, but some claim up to 10 years. Energizer Ultimate lithium claims 15 years; Energizer Advanced, 10.

    • How this young woman’s tragic night out changed our view of death

      On April 14, 1975, 21-year-old Karen Ann Quinlan partied with friends at a New Jersey bar, mixing gin and tranquilizers along the way. By the end of the night, she collapsed and fell into a permanent coma, igniting a firestorm that changed the way Americans looked at death. Quinlan sparked the right-to-die movement and came “to define modern death, more so than any other person in history,” according to the new book “Modern Death: How Medicine Changed the End of Life” by Dr. Haider Warraich. Hoping to fit into a dress, the young woman had eaten little in the days leading up to the party. After she collapsed at the bar, friends brought her back to her house and performed mouth-to-mouth resuscitation,

    • Got a Craving? Here's What Your Body Actually Wants You to Eat (9 photos)

      Ever find yourself rummaging through the fridge or kitchen cabinets for that delicious, satisfying something --except nothing seems to fill that void? Maybe you know what you're craving, but would actually have to leave the house to go and buy it (who wants to do that?), or your craving is so ambiguous that even browsing the supermarket aisles might leave you stuck. Turns out, there's more to your hankering than just hunger. "Often a food 'search' can arise when you're in need of a break from work or sitting, so by nature you get up and stir around," explains Lisa Cohn, RD, a New York City-based nutritionist. "Other times a quest can be triggered by an emotional or physical reaction that leaves us feeling frozen or out of control, and the act of searching for something to eat gives us a determination to take control." VIDEO: How to Make Banana Blueberry Overnight Oats While there are several other potential reasons for sudden cravings, including a nutrient deficiency, sleep deprivation, and low blood sugar, there are healthy and satisfying snack choices you can make to quench a craving until your next meal.

    • George Clooney Admits He "Chased" Amal For "Many Months" After They First Met

That is, until Amal Alamuddin (now Amal Clooney) came along. George first laid eyes on the human rights attorney at his home in Lake Como, Italy in 2013. During a previous appearance on the Late Show with David Letterman, the 55-year-old actor revealed, "We met in Lake Como. She was a friend of a friend who came to visit and then I chased her for many months, calling and writing, those kinds of things." George also admitted to Ellen DeGeneres that "from the minute we met, we just sort of felt like we were going to be together." He
