Is Duracell Optimum worth the extra cost over standard Duracell?

Optimum claims up to 200% extra life, so it pays off in high-drain devices like toys and controllers. For clocks and remotes, standard cells are cheaper and last long enough.

How long can these batteries sit in storage?

Duracell rates Optimum for up to 12 years of storage life. Keep them in a dry place at room temperature and leave them in the original pack.

Are these AAA or AA batteries?

This listing is the AAA size in an 8-pack. Duracell also sells Optimum in AA, so check the label before ordering.

Can I use these in a device that takes rechargeable batteries?

Yes, they are standard 1.5V alkaline AAA cells. They are not rechargeable, so do not put them in a charger.

What is the price and where is it sold?

The best new price is $36.00 at Amazon as of November 6, 2026. That is the only new price listed.

Will these leak if I leave them in a device?

Alkaline cells can leak over time, especially when drained. Remove them from devices you will not use for months.

Our take on the Duracell Optimum AAA Alkaline Batteries

Duracell Optimum AAA is Duracell's premium alkaline line, sold here in an 8-pack. It claims up to 200% extra life versus Duracell's standard alkaline cells and a 12-year storage life, and the pack uses no plastic. The best new price is $36.00 at Amazon as of November 6, 2026, the only new price listed, so there is no recent range to compare it against.
