Duracell Coppertop Alkaline Battery Review

You can find the Duracell Coppertop Alkaline Battery in many battery-operated devices including the following. It works well in every one of them.

  • Electronics like smoke detectors.
  • Universal remotes.
  • Thermostats.
  • Stud finders.
  • Circuit testers.
  • Atomic clocks.
  • Flashlights.
  • Cameras.
  • Digital recorders.
  • Lanterns.

Coppertop batteries supply long-lasting power.  That’s our big thought about them over the past couple decades that we used them,  Rarely have they leaked. Plus, they hold their charge on the shelf for years.

Duracell batteries appear almost like Energizer alkaline batteries.  That is, their power lasts just as long.  Shelf life is about the same. Plus, neither battery appears to leak any more than the other.  Both battery brands make the old carbon-zinc cells way dated. Duracells are indeed DURable and enDURing.

Benefits, Features, Pros, and Advantages of the Duracell Coppertop Alkaline Battery

Sold Almost Everywhere

First, most any store that sells batteries carries the Duracell line. So these cells are about as easy to find as they could be. Also, we often see them in discount stores at much lower prices.  So check out those great deal places first.

Dependable Power

Next, you get consistent, long-lasting power. No matter where you use these batteries. Whether you use the them right away or store them for several years first, they last.

Not Much Leakage

So we do not worry with leaving them in appliances for months (or years at times).

The Duracell Coppertop Alkaline Battery has a Lengthy Full Charge

Retain nearly a full charge for up to ten years on the shelf, thanks to Duracell’s Duralock Power Preserve design.

Guaranteed to Deliver

Then, they have a ten years in storage guarantee to boot.

No added Mercury

Works in Most Climates

Function well in very hot and very cold weather.

Feel Confident Storing Them

With their long shelf life, it’s safe to stockpile them.  Then you always have ready power nearby.

The Duracell Coppertop Alkaline Battery Includes a Best-By Date

Duracells display the best-used-by date on each battery. This date runs several years out on a fresh set.

Large Quantities Available

You get better deals when you buy Coppertops in bulk.  The smaller sizes you can buy in packs of eight, sixteen, or even thirty-six.

Devices Built for Coppertops

They design some appliances to work best with Coppertop batteries and their unique discharge behavior.

Deliver Nearly full Electricity Until the Very End

Coppertops show an interesting way of discharging.  That is, they don’t appear to GRADUALLY lose their power as you use them up.  Much like nickel-cadmium batters on the other hand, they deliver full voltage and current until they discharge all the way.

Then, they die hard, and the device stops running almost completely.  Have seen this in flashlights.  In our tests, battery operated things do not run partially with these batteries. E.g. They work fully until the batteries reach end-of-life.  Then, they shut down all the way.  This may not be true in lower current devices like remote controls and clocks.  But for things like boom boxes, bright flashlights, and toys. You get full power, for just about all of the battery’s usable life before it dies completely.

The Duracell Coppertop Alkaline Battery Comes in Standard Battery Sizes

Available in AAA, AA, C, D, and 9-volt sizes.

Easy to Find in Retail Outlets

The trademark Coppertop look is easy to spot on store shelves. No other battery looks like these.

Disadvantages, Limitations, Cons, and Problems of Duracell Coppertop Alkaline Batteries


Duracell Coppertop prices have gone higher over time. E.g. We found a pack of twenty AA Duracell batteries for $11.99 recently. With so many consumer devices these days needing batteries, monthly battery costs are as common as the electricity bill. So look for the best deal in batteries, as you’ll likely need lots of them.  So it’s nice to see Duracell and Energizer batteries in such tight competition for market share.

They can Still Leak

One still must worry that a battery will leak eventually. But with all the advances in materials and chemicals, you’d think this would issue would be solved.  So you’d think that they could guarantee a battery that never leaks. But not yet. However, these Duracell alkaline batteries leak the least of any battery we’ve tested.

The Duracell Coppertop Alkaline Battery is Not Rechargeable

At least, not officially.

Old Batteries Often Still Sold

Stores and online vendors sometimes do not remove expired batteries from the shelves.  So be careful to buy a fresh set.

Our Rating on the Duracell Coppertop Alkaline Battery

Over all, we like the many Duracell alkaline batteries we bought since the early 1990s. So we highly recommend them, as we rate this battery at 95 out of 100. Indeed, there are not too many criteria that make or break a good battery.  But Duracell Coppertop meets them all. They offer good fit in most any appliance, and of course, the seemingly endless power they supply.
