Which is cheaper per battery?

The Energizer. At $18.74 for 32 cells it is about 59 cents each, against about $1.25 each for the $14.99 Duracell 12-pack, as of November 3, 2026.

Which lasts longer in storage?

Energizer states up to 10 years in storage. Duracell does not state a shelf life for the Optimum pack in the listing, so the Energizer is the safer pick for a drawer or emergency kit.

Is the Duracell worth the extra per battery?

Only if you want a small pack or prefer Duracell's premium line. Per cell it costs roughly twice as much, and no stated capacity or shelf life backs up a premium here.

Which is better for a wireless mouse or TV remote?

Either works; both are 1.5 V alkaline AAA. For low-drain devices like remotes, the cheaper Energizer cells make more sense because you will replace them rarely.

Are these really AAA batteries?

The Duracell pack is listed as AAA. The Energizer listing is titled AAA and described as 32 AAA cells, but one spec field says AA, so check the pack label on arrival.

How many stores carry each?

Both are priced new at 3 stores as of November 3, 2026. The best prices were $14.99 at PC Richard & Son for Duracell and $18.74 at Amazon for Energizer.
