The most revolutionary innovation ever made by Duracell, the Duracell Optimum alkaline battery features a new cathode system capable of providing up to 100% extra life in some devices or extra power in other devices. Duracell Optimum AA lasts longer in some devices such as toys and has extra power compared to other Duracell alkaline batteries in a wide range of devices. With Duracell Optimum, motors run faster in devices like remote-controlled cars, and optimal performance comes together in an optimized package. Thanks to the new packaging, the batteries remain stored in an orderly and safe manner inside their packaging until the next use. Once used up, you can store them back in the packaging while waiting to recycle them. The packaging is 100% recyclable and made with 0% plastic.
