We compared two alkaline AA multipacks at almost the same price: the 12-pack Duracell Plus and the 48-pack Amazon Basics.

What we looked at

Pack size, cost per battery, stated life and leak protection, shelf life, and price. Both are non-rechargeable alkaline batteries.

The verdict

If you want the Duracell name with a stated up to 150% extra life from Power Boost Actives, a nylon top closure against leakage and plastic-free packaging, the 12-pack Duracell Plus is the brand pick, at £11.95, about £1.00 a battery. If you just want plenty of AAs, the 48-pack Amazon Basics costs £11.70, about 24p a battery, with a stated 10-year leak-free shelf life.
