s, 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.


Properties

A C-battery measures length and diameter. 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 ''Mångha'' (') is the Avestan for "Moon, month", equivalent to Persian ''Māh'' (; Old Persian ). It is the name of the lunar deity in Zoroastrianism. The Iranian word is masculine. Although Mah is not a prominent deity in the Avestan script ...
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.


Standardisation

Like the
