Nickel oxyhydroxide battery cells. Nickel oxyhydroxide battery Nickel oxyhydroxide battery (abbr. NiOx, IEC code: Z) is a type of primary cell. It is not rechargeable and must be disposed after a single use. NiOx batteries can be used in high-drain applications such as digital cameras. NiOx batteries used in low-drain applications, have a lifespan similar to an alkaline battery. NiOx batteries produce a higher voltage (1.7V) than alkaline batteries (1.5V) which can cause problems in certain products, such as equipment with incandescent light bulbs (such as flashlights/torches), or devices without a voltage regulator. The nickel oxyhydroxide cell is different from a standard alkaline
C battery mAh, rechargeable NiMH 'C' batteries can hold up to 6,000 mAh, and zinc-carbon 'C' batteries usually hold up to 3,800 mAh. Like the D battery, the C battery size has been standardized since the 1920s. The AA, AAA, and N sizes have been in common use since the 1950s. The C battery is called "14" in current ANSI standards of battery nomenclature, and in IEC standards is designated "R14". C battery The C' 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,
