The best AA batteries last more than two and a half hours longer than the worst in your most power-hungry devices. We compare the best and worst directly to help you find your ideal AA battery.

Put a set of one of our Best Buy AA disposable batteries in your most power-hungry devices, such as a camera or torch, and they will last nearly two and a half hours longer than the worst. Put them in a medium-drain device, like a games console, and you'll get nearly seven extra hours.

No one else tests like Which? – our independent lab tests simulate the way you really use batteries, so you can be confident that our Best Buy AA batteries will power your devices for longer. Our latest tests included AA batteries from Duracell and Energizer in our quest to find the best batteries for your gadgets.

As well as testing how long batteries last under different conditions, we calculate the cost per hour for each battery and reveal which batteries are most and least likely to leak.
