Duralock technology keeps unused Duracell batteries fresh and powered for up to 10 years in ambient storage. With Superior Nylon top closure helps preventing our batteries from leakage. Duracell Coppertop batteries give you the freedom to enjoy the use of your appliances by giving you a product you can rely on.
Please note since 2019, Duracell no longer prints the silver banner on batteries which state "DURALOCK". Expiry can be found on the top of each battery for confirmation.
