To fit virtually every device out there, CopperTop alkaline batteries are available in AAA, AA, C, D, and 9V sizes.

Duracell manufactures alkaline batteries in many common sizes, such as AAA, AA, C, D, and 9V, but capacity of Duracell batteries can’t be found on the official Duracell site (www.duracell.com). Lesser used sizes such as AAAA (primarily for pagers, penlights, and blood glucose meters) and J size batteries (for hospital devices and photographic strobe flash units) are also manufactured along with a range of “button” batteries using zinc-air, silver-oxide and lithium chemistries, used in calculators, watches, hearing aids, and other small (mostly medical related) devices. Duracell entered into a brand licensing agreement with flash memory manufacturer Dane-Elec in 2008 for a line of products including memory cards, hard drives and USB flash drives with the Duracell brand mark and in the brand’s trademark “copper top” coloring.

Duracell also manufactures specialty batteries, including NiMH rechargeable batteries and batteries for cameras, watches, hearing aids, etc. Their two main battery brands are “CopperTop (Plus),” marketed as longer-lasting, and “Ultra,” directed mainly at users of digital devices and devices that need more power. Duracell also has a line of lithium chemistry batteries and products, now manufactured outside of the U.S.

In 2013 the company released a new “Duracell Quantum” line as their top performing product series.

In recent years, Duracell’s innovations expanded to include new battery designs with their prismatic batteries, which are prismatic in shape rather than cylindrical. Prismatic cells were made available in both alkaline and lithium designs. In 2006, Duracell introduced “Power PixTM” batteries with NiOx technology, designed to supply longer life in digital cameras and other high drain devices by up to twice the number of photos typically achievable with alkaline batteries.

Duracell batteries are also bulk packaged for end users under the brand name Procell.


Duracell Review

Bottom Line

Duracell CopperTop alkaline batteries are a decent choice if you’re looking to buy non-rechargeable
cells since they are reported to be reliable and affordable. Expert opinion chooses Duracell CopperTop over more expensive alkalines, because there is no significant difference in quality between them for this reason.

Staying Power

CopperTops have a decent lifespan. PopPhoto.com’s Zach Honig tested a number of rechargeable and disposable batteries. In his tests, Duracell CopperTop came in second. The CopperTop batteries captured 1,204 shots without flash and 668 shots with flash.
Amazon.com reviewer Sarah Schmitt calls herself a “Coppertop convert” after the batteries lasted four times longer than Energizer rechargeables when used with her Canon digital point-and-shoot camera. Three weeks into using the batteries with her camera, she still hadn’t worn them out. She also mentions that her CopperTops outperformed Energizer rechargeables when she used them for her Xbox controllers.


Comparable to more expensive batteries. Reviews say that there isn’t a big difference in quality between alkaline batteries at different price points. CopperTop are frequently recommended because of their relative value. CopperTops receive mostly glowing 5-star reviews on Amazon.com, where customers rave about their reliability and good price. Some of the 1-star reviews complain of opened packages and battery leakage.

This review is from: Duracell Coppertop AA Batteries, 28-Count (Health and Beauty)
Because my job requires lots of photos and flashlight use, I’ve tried brand name to bargain brands for years. Seems I always come back to these AA Duracell type. Based on my experiences, this brand goes the longest and you can switch them around in the camera to really drain them. They work, they last. This package is also an easy one to use. The straight-line storage doesn’t let them spill around, you can fold, tape or rubber-band the open end of the pack.
