The honest bit

Rechargeables need power to recharge. Keep a stock of ordinary alkaline batteries too, or a power station or solar to recharge from.

Before you buy

Choose low self-discharge (pre-charged) NiMH: they hold charge in storage, which matters for emergency kits.

Capacity (mAh) is runtime per charge; cycle rating is how many times you can recharge.

Budget high-capacity labels are often optimistic; established brands are more consistent.

Use a charger that handles cells individually.

How we choose

We verify every product's specifications against at least two independent sources, re-check its US price and stock on a schedule where we can track it automatically, and cross-check safety-relevant claims against official guidance. Every review is labelled Researched or Used and reviewed by us: where we've bought a product, or been sent it free, and used it ourselves, its review says which; where we haven't, our verdict is a considered spec-and-evidence comparison, not a hands-on test — and commissions never change a ranking either way.

Common questions

Are rechargeable batteries good for emergencies?

Low self-discharge types are: they stay charged in storage. Keep some alkalines too, in case you can't recharge.

Which rechargeable AA holds its charge longest?

Standard eneloop is known for holding charge for years in storage; Panasonic quotes a 10-year figure.

What does mAh mean?

Milliamp-hours: how much energy the battery stores, so how long it runs per charge.

Do I need a special charger?

Use a NiMH charger, ideally one that charges cells individually, like the eneloop charger here.
