The C battery (C size battery or R14 battery) is a standard size of dry cell battery typically used in medium-drain applications such as toys, flashlights, and musical instruments.

As of 2007, C batteries accounted for 4% of alkaline primary battery sales in the United States. In Switzerland as of 2008, C batteries totalled 5.4% of primary battery sales and 3.4% of secondary (rechargeable) battery sales.[http://www.epbaeurope.net/documents/NEMA_alkalinelca2011.pdf Life Cycle Impacts of Alkaline Batteries with a Focus on End-of-Life – EPBA-EU] {{webarchive|url=https://web.archive.org/web/20111007014825/http://www.epbaeurope.net/documents/NEMA_alkalinelca2011.pdf |date=7 October 2011 }}[https://web.archive.org/web/20120325171702/http://www.inobat.ch/fileadmin/user_upload/pdf_09/Absatz_Statistik_2008.pdf] INOBAT 2008 statistics.

Properties

A C battery measures {{convert|50|mm|in|2|abbr=on}} length and {{convert|26.2|mm|in|2|abbr=on}} diameter.IEC 60086-2 §7.1.3

The voltage and capacity of a C-size battery depends on the battery chemistry and discharge conditions. The nominal voltage is 1.5V. Alkaline C batteries have a storage capacity up to 8000 mAh while rechargeable NiMH C batteries can hold up to 6000 mAh. Zinc-carbon C batteries usually hold up to 3800 mAh. Compared to the AAA and AA batteries, C-batteries' storage capacities are significantly higher.{{Cite web |title=C Battery – TechNotes |url=https://www.technotes.org/entry/tc-batt-c |access-date=2022-12-03 |website=www.technotes.org}}

Standardisation

Like the D battery, the C battery size has been standardized since the 1920s.Ron Runkles (ed) A Brief History of the Standardization of Portable Cells and Batteries in the United States, American National Standards Institute Accredited Standards Committee C18 on Portable Cells and Batteries, 2002, [https://wayback.archive-it.org/all/20120802183313/http://www.swe.com/admin/FILES/ANSI%20Battery%20Standardization%20History.pdf ANSI Battery Standardization History, 2010 Jan 9] The AA, AAA, and N sizes have been in common use since the 1950s.{{ cite journal | journal = Popular Science | title = Clever New Gadgets Run on Flashlight Batteries | author = Howard G. McEntee | volume = 174 | issue = 3 | publisher = Bonnier Corporation | page = 132 | issn = 0161-7370 | date = March 1959 | url = https://books.google.com/books?id=9iUDAAAAMBAJ&pg=RA1-PA132 }} It is descended from the old No. 1 dry cell battery for flashlights which was of a similar size, originally the zinc casing was formed around a broom handle.

The C battery is called "14" in current ANSI standards of battery nomenclature, and in IEC standards is designated "R14".
