Detailed overview: Duracell Coppertop C alkaline battery
Duracell Coppertop C batteries are 1.5-volt alkaline batteries in the medium cylindrical format. Larger than an AA but smaller than a D, they offer higher capacity and runtime, suited to devices that draw more power than a typical household gadget.
They are used notably in flashlights, portable radios, clock radios, bulky toys, electronic musical instruments, some night lights and a range of medium-sized household devices. Thanks to their generous cylindrical format, they outlast smaller batteries on demanding uses.
Sold here in a pack of 4, in their original Duracell packaging, these batteries are built under the brand's strict manufacturing standards and every Duracell battery is guaranteed against defects in material and workmanship. They also carry a 10-year shelf life, which makes them a smart choice for spare batteries you do not plan to use right away.
Like all alkaline batteries, the C cell is single-use and should be recycled at end of life through a battery collection program. Reliable and long-lasting, this Duracell Coppertop C pack is a dependable pick for any device that needs a medium-size 1.5V cylindrical battery.
Our tester's review: Pierre Freysinger
The C battery is the format people forget exists until a specific flashlight or portable radio demands it, and Duracell's Coppertop line covers that need without any surprises. We have run a set through a heavy-duty flashlight kept in a garage toolbox, and it delivered steady, bright output through months of occasional use before finally fading. Where the C size earns its keep is in devices between an AA and a D in power draw, things like bigger portable radios and electronic instruments, where an AA would not last and a D would be overkill on size. The pack of 4 covers most single-device needs comfortably. Duracell backs these with the same 10-year storage guarantee as the rest of the Coppertop line, so a spare pack tucked away for a rarely used device or an emergency kit will still be good years later. Nothing about a C battery is exciting, and that is fine: it is a dependable, widely stocked size that does exactly what it says on the label.
