Disposable AA batteries

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

June 2024


Super 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 Eveready Super Heavy Duty performs terribly across the board in comparison. In addition, many of the alkaline batteries we tested were cheaper to buy than the Eveready Super Heavy Duty.

Definitely not worth buying

Look good. Will work if not worried bout the cons happening.


These are the worst batteries to degrade quickly over short period of time and if you forget to remove them from item you put them in they deteriorate quickly and start leaking causing damage to said item. No other battery l've used does this. I've even found leaking unused batteries in packaging l haven't used, yet still well within their best before date.

Recommend it?

Maybe, it depends on what you're after.
