Battery Cell Types


The following table is a list of primary battery sizes which are currently available in modern society. Note that there were other sizes other than those listed in this table which are no longer 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.

Naming Notes

CR# / BR# / SR# / LR# Button Cells (where the code contains 3 to 4 numeric digits): Uses an alphanumeric coding system defined by the International Electrotechnical Commission (IEC) in its current 60086-3 standard (Primary batteries, part 3 Watch batteries). Examples of this code are batteries coded CR2032, SR516, and LR1154 where the letters and numbers in that code indicate the battery's characteristics. The numbers in the code correlate with the cell dimensions, being the diameter in millimetres (except for the extra half millimetre in some cases) followed by the height in tenths of a millimetre. SR and LR button cells where the code contains only one or two numeric digits conform to an older international standard.

SR# / LR# / AG# / SG# Button Cells: IEC SR series batteries are silver oxide chemistry and provide 1.55 volts, while IEC LR series batteries are alkaline chemistry and provide 1.5 volts. Similarly, SG series batteries are the silver oxide chemistry version of the AG series where AG usually indicates alkaline chemistry. Since there are no 'common' names beyond the AG# designation, many places use these four designations interchangeably for the same sized cell, and they will all fit and work. The only difference is that silver oxide chemistry typically has 50% greater capacity than alkaline chemistry. In low-drain devices like watches (without lights) this isn't very important, but in high-drain devices like blinkies, key chain flashlights, or laser pointers silver oxide is preferred. Typically all four types will be the same price unless one buys in wholesale volume so there is no reason not to get the silver oxide version. Often the free 'demo' batteries that come with a device are the alkaline version.

IEC CR# / BR# Button Cells: CR denotes Manganese dioxide Lithium chemistry. Since LiMnO2 cells produce 3 volts there are no widely available alternate chemistries for a CR coin battery. Conversely one LiMnO2 cell can replace two alternate chemistry cells, in a 3, 6, 9, or 12 volt secondary battery. Though often hard to find, some CR sizes are also sold designated as BR, such as the BR2032. BR types have a slightly different chemistry (Poly-carbon monofluoride Lithium) giving a higher capacity but at the expense of maximum discharge current. They are more suited to memory retention applications.

Button / Coin / Watch / Micro / Miniature: In many places these are used interchangeably.
