It is not pleasant when a AA battery leaks - the discharge is toxic and it damages the device that the battery was plugged into. Leakage resistance: Lithium batteries are much less likely to leak than alkaline batteries.Alkaline BatteriesĪlthough lithium batteries cost more than alkaline batteries, they are a better buy because of the following reasons: A comparison from Duracell's website is presented below.Ĭomparison of alkaline batteries from Duracell ( see current deals on Walmart) Lithium vs. The technical specifications of Procell and CopperTop are identical. Varietiesĭuracell offers batteries under the Procell, CopperTop and Ultra brands. (I did however never experience a failure with Energizer) Duracells leak more, even brand new, still in the package. I read too many horror stories about Energizer to not get it. I've had a number of Energizers leak goo, but never with the Duracells.
The following comments from Internet discussion boards are not based on any scientific research and are, therefore, questionable. A YouTube video suggests that Energizer batteries leak acid after they expire - even if they are unopened, whereas Duracell batteries do not. During the 1990s, Energizer removed Mercury and Cadmium from all household batteries (AAA, AA, C, D and 9V), introducing the first zero-added mercury battery in the United States.Īnecdotal evidence suggests there are some leakage problems and safety issues with both brands. Energizer supports the Rechargeable Battery Recycling Corporation.

Duracell funds Call2Recycle, a free battery and cellphone recycling program. The environmentally friendly and "green" way of living is to use rechargeable batteries whenever possible.īoth companies claim to support programs that promote battery recycling. While alkaline batteries can be thrown away with regular trash, lithium batteries must be disposed of specially. Overall sales for Duracell batteries are around $2.5 billion. Energizer Max Alkaline AA Battery, 24-Countĭuracell has about 29% market share and Energizer about 25%.Duracell Procell AA Batteries, 24-Count.However, prices may vary depending upon the retailer and any promotional offers. In general, Duracell batteries are costlier than Energizer. Given that the differences between most AA batteries are not very significant, it is often easiest to buy whichever batteries are cheaper. Results of a scientific test of battery life Price The results were mixed and are presented below. In a Canton State University of New York test, Energizer and Duracell batteries of various brands were tested under varying ambient conditions. Tests with different brands and different ambient conditions This video from Consumer Reports reveals some interesting findings not just about Duracell and Energizer but their specific variants, as well as their comparison with Walgreens-branded batteries. Anecdotal evidence from the author suggests that Energizer AA batteries lasted longer (up to three times) than Duracell AA batteries when used in clocks. Duracell was found to outperform Energizer. In another experiment, C batteries from Duracell and Energizer were compared for continuous use with a Flashlight.
Higher is usually better but the battery life findings were contrary to the listed mAh ratings of the batteries. mAh stands for milliampere-hours, which is a unit of electric charge.
Both companies batteries are NiMH (nickel metal hydride) the Duracells are 2000 mAh and the Energizer batteries are 2200 mAh. When comparing rechargeable AA batteries, Gizmodo found that Duracell lasted longer (5 to 6.5 hours) than Energizer batteries (2 to 3.5 hours).
