Duracell Coppertop Size D Batteries – Pack of 12

Your smoke alarm chirps at 3am and the battery's flat. Your torch dies mid-hike. You need power that actually holds up, not another pack that fades by Thursday.

Duracell Coppertop Size D, 12 to a pack. Duralock Power Preserve tech keeps the charge locked in so your torch, portable radio, smoke alarm or game console stays powered through the week — not just the morning. Drop them in, close the lid, done.
