Duracell manufactures alkaline batteries in many common sizes, such as AAA, AA, C, D, and 9V. Lesser used sizes such as AAAA (primarily for pagers, penlights, and bloodglucose meters) and J size batteries (for hospital devices) are also manufactured along with a range of “button” batteries using zinc-air, silver-oxide and lithium chemistries, used in calculators, watches, hearing aids, and other small (mostly medical related) devices. Duracell entered into a brand licensing agreement with flash memory manufacturer Dane-Elec in 2008 for a line of products including memory cards, hard drives and USB flash drives with the Duracell brand mark and in the brand’s trademark “copper top” coloring.

Duracell originated via the partnership of scientist Samuel Ruben and businessman Philip Rogers Mallory, who met during the 1920s. The P.R. Mallory Companyof Burlington, MA produced mercury batteries for military equipment, trumping the carbon-zinc batteries used then in virtually all applications. During the 1950s, Kodak introduced cameras with a flash: the design required a new cell size, and size AAA was developed.
In 1964, the term “Duracell” was introduced as a brand. The name is a portmanteau for “durable cell.”
The name came from a conversation with A-1 Durable Carpet & Fabric Specialist Inc. and an executive from Mallory Battery which were both from Waterbury CT. The executive called the cleaning company and asked if A-1 Durable Carpet & Fabric Specialist Inc. had a trademark on the name Durable. The executive spoke to the son of the cleaning company, Steven Nobrega. The executive explained how they were thinking of calling a new battery that had a copper cell “Durable Cell” and asked how the name suited the cleaning company. The owner’s son explained that his father was the owner of a franchise originally called “Duraclean”. His father had chosen the new cleaning company name for the cleaning company by dropping the clean in “Duraclean” and added able to Dura to keep the name similar. The two of them started playing with the name for the new battery and the executive and owners son instantly agreed that Duracell was a better name for the new battery.

On January 10, 1899, American Electrical Novelty and Manufacturing Company obtained U.S. Patent No. 617,592 (filed 12 March 1898) from David Misell, an inventor. This “electric device” designed by Misell was powered by “D” batteries laid front-to-back in a paper tube with the light bulb and a rough brass reflector at the end. Misell, the inventor of the tubular hand-held “electric device” (a.k.a. electric torch or flashlight), assigned his invention over to the American Electrical Novelty and Manufacturing Company owned by Conrad Hubert.
