Duracell and Kirkland Signature offer batteries that are nearly as effective as Energizer, though no commercial batteries are as effective as Energizer’s expensive Ultimate line, according to Consumer Reports. Duracell offers nearly comparable performance, while Kirkland Signature batteries offer strong value for their price.
Duracell’s Quantum and CopperTop lines both receive high marks, though neither lasts quite as long as Energizer’s Ultimate. Both Duracell batteries win strong ratings for durability, shelf life and reliability, placing them above most other comparably priced brands.
Value brand Kirklands Signature batteries receive the best ratings among bargain brands, winning a coveted Best Buy designation from Consumer Reports. Although the batteries are only available in packs of 48, their extremely low cost makes them a good deal for users who don’t mind slightly shorter battery life.
