Disposable AA batteries

We tested 15 models of 1.5V disposable AA batteries to see which lasted longest.

Extra Heavy Duty

Prices are what we paid per battery.
Don't buy

We don't recommend any carbon zinc batteries because alkaline and lithium perform considerably better and have longer shelf lives. The Panasonic Extra Heavy Duty performs terribly across the board in comparison. In addition, many of the alkaline batteries we tested were cheaper to buy than the Panasonic Extra Heavy Duty.
