Many commonly available size D rechargeable cells are actually sub-C cells in a D-sized holder. This effect is generally less pronounced in cells with NiMH chemistry and hardly at all with NiCd. Duracell brand rates its alkaline D cell performance as approximately 20,000 mAh at 25 mA draw, but about 10,000 mAh at 500 mA draw. When you see a letter used more than once (eg. Names Common Name / Type of this batteryĪ battery's capacity depends upon its cell chemistry and current draw. Basically, the farther you get through the alphabet, the larger the battery (e.g. They are: 50mm or 1.97 inches in length 26.2mm or 1.03 inches in diameter. The overall length is 61.5 millimeters (2.42 inches). C-sized batteries are smaller than D batteries but larger than AA and AAA batteries. This standard battery comes as both primary and rechargeable batteries. ĭ, C, AA, AAA, AAAA and 9-Volt batteries Dimensions and capacity ĭ batteries have nominal diameter of 33.2 ± 1 millimeters (1.3 inches). The C size-battery is 1.97 inches or 50.0 mm in length and 1.03 inches or 26.2 mm in diameter. In 2008, Swiss purchases of D batteries amounted to 3.4% of primary and 1.4% of secondary (rechargeable) sales. In 2007, D batteries accounted for 8% of alkaline primary battery sales (numerically) in the US. Navy, leading to confusion with the smaller C cell battery (BA-42). During World War II, it was designated the Type C battery by the U.S. military designation for this battery has been BA-30 since sometime before World War II. As of 2007, C batteries accounted for 4 of alkaline primary battery sales in the United States. It is important to note that these are only standard measurements the. The standard height and diameter for C batteries are 49.5 0.5 mm and 25.3 0.2 mm, respectively, while D batteries measure 59.0 0.5 mm and 61.5mm x 33.2mm, respectively. Before smaller cells became more common, D cells were widely known as flashlight batteries. 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. Similarly, C and D batteries differ in diameter and height, with C batteries measuring less. of batteries as you should in California, there is little difference in the. The National Carbon Company introduced the first D cell in 1898. The newer LSD batteries have entered the market in sizes AAA, AA, C, D and 9. Its terminal voltage and capacity depend upon its cell chemistry. A D cell may be either rechargeable or non-rechargeable. D cells are typically used in high current drain applications, such as in large flashlights, radio receivers, and transmitters, and other devices that require an extended running time. A D cell is cylindrical with an electrical contact at each end the positive end has a nub or bump. D cell batteries, wooden matchstick for scale.Ī D battery ( D cell or IEC R20) is a standardized size of a dry cell.
