This 12 pack tub is available to buy online in small and large quantities. The larger quantity purchased, the bigger the saving. If these tubs are purchased in large/bulk quantities the monetary saving increases. You won’t have to use the right away as the Duracell Plus Size C battery has DuraLock power, which allows the preservation of power even when on the shelf of up to ten years. This pack appears particularly ideal for those who use high energy devices on a regular basis, whether at home or at work. Sometimes no matter how powerful the battery, frequent replacement is necessary due to high usage, this pack is ideal in such situations as it is a more economical option as opposed to multiple purchases of smaller packs.
