The terminal voltage of a battery depends on the chemicals it uses. For example, primary (non-rechargeable) alkaline batteries have a nominal voltage of 1.5 Volts. Rechargeable NiCd (Nickel Cadmium) and NiMH (Nickel Metal Hydride) typically output 1.25 Volts per cell. Devices intended for use with primary batteries may not operate properly with these cells, given the 16% reduction in voltage.
The battery designation in some cases also identifies not only the size, shape and terminal layout of the battery but also the voltage and chemistry. For example, a CR123 battery is always LiMnO2 ('Lithium') chemistry, in addition to its unique size.
The following tables give the common battery chemistries for the current common sizes of batteries. See Battery Chemistries for a list.
Manufacturers may assign novel names and numbers to their batteries, disregarding common, colloquial, IEC, and ANSI naming conventions (see LR44 battery as an example). Often this is done to steer customers towards a specific brand, and away from competing or generic brands, by obfuscating the common name. For example, if a remote control needs a new battery and the battery compartment has the label, "Replace with CX472 type battery," many customers will buy that specific brand, not realizing that this is simply a brand name for a common type of battery. In this article, brand-specific names have been purposely omitted to avoid confusion.
On the other hand, with obscure battery types, the name of a specific brand will sometimes become the most common name for that battery type, as other manufacturers copy or modify the name so that customers recognize it.
The following table is a list of primary battery sizes currently available. Other sizes not listed in this table may no longer be available due to either a decline in popularity or changing technological needs. Batteries for obsolete portable vacuum tubes devices for example, are not listed. A table of older, obsolete, and uncommon-availability batteries types and sizes can be found below this table.
