Presented in sophisticated, recyclable packing that is ideal for storage, this pack of 12 Duracell Optimum AA (LR6) batteries has been manufactured to increase longevity in devices. These alkaline batteries are 1.5V and contain a new cathode system. This allows the batteries to provide up to 200% extra life to your device as they run at a higher-than-average voltage. They also have the potential to deliver extra power to some motorised gadgets, allowing them to run smoothly. Aimed at use in medium to high drain devices, these are an economical option due to fewer replacements required.
