Most batteries slowly lose power over time, even when not in use. But Duralock technology keeps unused batteries fresh and powered for up to 10 years in ambient storage. So you can stock up on Duracell batteries without worry.
Ordinary zinc-carbon batteries contain fewer active ingredients inside and lose energy over time as chemical reactions go on constantly. Unlike zinc-carbon batteries, Duracell is filled with 2 times more active ingredients, which are locked inside a unique durable construction. It prevents battery leakage and helps the battery last significantly longer. Duralock is an exclusive power preservation system, which saves energy so effectively that your battery is guaranteed to stay powered for up to 10 years in ambient storage.
