The Duracell Coppertop series is one of the top battery choices for providing a long-lasting power solution for your gadgets and everyday devices.
The range of batteries in this series covers all the standard sizes for regular appliances including AAA, AA C, D, 6V and 9V.
Here’s a guide to Duracell Coppertop batteries for all your battery-powered devices.
What Are Coppertop Batteries?
Coppertop batteries are alkaline batteries that you can use for a variety of everyday portable devices like your calculators, remote controls and torches.
The batteries use zinc and manganese dioxide as electrodes and either sodium or potassium hydroxide as the electrolyte.
These batteries have a distinct advantage over ordinary carbon-zinc AA and AAA ones because of their higher energy densities. Plus, they last longer when in use, and even after long periods of storage.
They have an energy density of 0.4 – 0.59 MJ/kg vs ordinary carbon-zinc energy density of 0.13MJ/kg.
Note: MJ/kg measure the megajoules of power produced by a battery of specific weight. The higher the MJ/kg density, the better the battery's performance.
They also have a lower rate of self-discharge and last longer than ordinary carbon-zinc AA and other battery types. This means you can store them for up to 10 years and still get long-lasting power after that many years of storage.
This series of Duracell batteries is also available in alkaline AA, AAA and other standard sizes. You can easily identify them by their characteristic raised copper coloured top.
In terms of their performance, they have been known to be efficient and reliable. They come with a Duracell guarantee against defects in the materials and workmanship during the manufacture of the cells.

Here are some of the battery options available in this Duracell range.
Duracell Coppertop AA Batteries
The Duracell AA battery is an alkaline AA battery that gives a 1.5 V power source with longer-lasting power.
These Duracell AA batteries proved they could hold their own when tested against ordinary carbon-zinc AA ones in the IEC tests. They lasted 50% longer vs ordinary carbon-zinc batteries.
Note: They have a capacity of 2850mAh which means they can give 2850 milliamperes of power for every hour of use.
These alkaline AA batteries are the same size as standard ordinary carbon-zinc AA ones at a length of 13.5cm.
AAA Coppertop Battery
The AAA batteries are standard AAA sized, 1.5-volt batteries with Duralock technology. This technology preserves the batteries power for up to 10 years in storage.
Note AAA cells are 10.5mm thick and 44.5mm long.
The cells have a capacity of 1150 mAh, which is higher than the average capacity of a comparable non-alkaline carbon-zinc battery of 400-600mAh.
As the name suggests, these alkaline 9V Duracell batteries produce a nominal voltage of 9 volts.
The batteries operate at a capacity of 2400mAh and an actual voltage of between 9.6V and 4.8 V.
9V coppertop batteries are designed for use in devices like smoke detectors and garage door openers.
With the trusted Duralock preserve technology, the cells can stay in storage for five years and still give you the characteristic long-lasting power when you use them.
C4 alkaline batteries have a nominal 1.5 voltage. Plus, they have a high capacity of 7000mAh, so they can power high output devices like your portable electronics and LED torches.
They measure 50 x 26 mm and can last up to 10 years in storage.
Duracell 6V Coppertop Battery
Duracell’s 6V battery powers your advanced performance devices like lanterns and electric torches. This is because of their low internal resistance below 10 Ohms, which can handle power spikes well.
Built with long-lasting performance in mind, the cells operate at a capacity of 13000mAh. Their high power capacity makes them suited for high drain devices.

Understanding the Chemistry of Duracell Alkaline Batteries
So what makes the Duracell coppertop batteries tick?
For starters, they are made with technology that involves a specialised feature which allows the battery to store power extremely well. With this technology, the cells will only activate when you put them inside a device and switch it on.
This means as long as you store them in a cool, dry place, you can keep the batteries for ten years in storage and they’ll be just as good as new when you use them.
Check out this video for a glimpse of how Duracell batteries are made to perfection.
In addition, Duralock technology makes the Duracell battery even more reliable. The two electrodes have an extra layer of a separating material between them to stop any power transferring between the two when the cell is in storage.
Plus, the external casing is made of a three-ply layer of corrosion-resistant, pure materials to stop leaking and self-discharge.
Frequently Asked Questions
How Do I Get the Most Life Out of My Duracell Alkaline batteries?
Duracell alkaline batteries are non-rechargeable, so avoid tampering with or attempting to charge them. Only charge batteries that are marked rechargeable; otherwise, you risk them rupturing and dangerous electrolytes leaking out.
The best way to get your batteries to last long is to ensure you turn off your devices when they are not in use.
If you will not be using any of your devices for some time, remove the batteries and store them in a cool, dry place, ensuring that the contacts don’t touch.
Remember to avoid storing your batteries in hot places like kitchen drawers or cold places like the refrigerator. Instead, store your batteries at room temperature.
Do Duracell Batteries Really Last For Ten Years?
Duracell batteries have a manufacturer guarantee to last for up to 10 years (depending on the type) when stored correctly.
However, if they aren’t stored properly, they can deteriorate or self-discharge.
For your batteries to last according to Duracell standards, avoid exposing them to extreme temperatures.
Both heat and extreme cold will affect the stability of the electrolyte, which will reduce the efficiency of your batteries.

Here’s what others had to say about their experience with us:
The service is beyond what I expected. No stock when I ordered, but I had a phone call a couple of days later to say that they are on the way. Service is beyond what I expected and I would recommend you give them a try. Dave T.
Excellent service. Recently purchased from HB a somewhat hard to get battery. Delivery was very timely, and I even had a phone call to advise of a short delay, communication which is rare for even some much larger companies. I would recommend this business. Bruce M.
