Battery (electricity)

In electronics, a battery or voltaic cell is a combination of one or more electrochemical cell Galvanic cells which store chemical energy that can be converted into electric potential energy, creating electricity....
size generally refers to the shape, voltage, and terminal layout of a battery. Thus the term "size" has become interchangeable with "type". Batteries of different types will usually not have the same dimensions and terminal layout.

Non-standard brand-specific names

Battery naming is further confused by the practice of manufacturers that assign novel names and numbers to their batteries, disregarding common, colloquial, IEC, and ANSI naming conventions (see LR44 battery

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.

Table of modern battery sizes

The following table is a list of 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.

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. Since there are no 'common' names beyond the AG# designation, many places use these three terms interchangeably, and they will all fit and work. The only difference is that the SR series typically have 50% greater capacity than the LR series. In low-drain devices like watches (without lights) this isn't very important, but in high-drain devices like blinkies
Blinky (Novelty)

Blinkies are small electronic devices that make very bright light using LEDs and small batteries. They are often sold by vendors at night-time events that have fireworks displays such as Independence Day , Canada Day, or Guy Fawkes Night....

s the SR type is preferred. Typically SR and LR will be the same price unless one buys in wholesale volume so there is no reason not to get the SR version. Often the free 'demo' batteries that come with a device are the LR version.

IEC CR# series: Denotes lithium–manganese dioxide chemistry. Since LiMnO₂ cells produce 3 volts there are usually no 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 battery. CR cell numbers 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. Note also that some 'CR' sizes are also sold designated as 'BR', such as the BR2032, though often hard to find. These latter types have a slightly diferent chemistry giving a higher capacity but the expense of maximum discharge current. They are more suited to memory retention applications.
Button / Coin / Miniature: In many places these are used interchangeably.
