DUROPT1500B8PRT OPTIMUM ALKALINE AA BATTERIES, 8/PACK

Duracell's most groundbreaking innovation yet. The all new Duracell Optimum alkaline battery has a new cathode system that can give your device Extra Life—like toys that run longer—or Extra Power—like brighter flashlights. Optimum batteries are packaged in a new slider pack with a resealable storage tray, that provides a more organized way to store your batteries (no more loose batteries everywhere!).
