Are Duracell batteries any good?
Duracell's mainstream AA batteries don't excel in any area, but they're good all-round performers and worth picking up if you find them on sale. Duracell claims they deliver 50% more power than most AA batteries, and you still get Duralock technology to keep them fresh for up to ten years in storage.Feb 1, 2021
