List of battery sizes
Encyclopedia
This article lists the sizes and shapes of some common primary and secondary battery types in household and light industrial use.

The long history of disposable dry cells means that many different manufacturer-specific and national standards were used to designate sizes, long before international standards were reached. Technical standards for battery sizes and types are published by standards organization

 (ANSI). Popular sizes are still referred to by old standard or manufacturer designations, and some non-systematic designations have been included in current international standards due to wide use.

The complete nomenclature for the battery will fully specify the size, chemistry, terminal arrangements and special characteristics of a battery. The same physically interchangeable cell size or battery size may have widely different characteristics; physical interchangeability is not the sole factor in substitution of batteries.

A battery may consist of a single cell or two or more cells in a single package, such as the 2CR5 (two lithium cells) or a 4LR44 (four alkaline LR44 cells), or a 1604 9-volt battery which has six cells.

 (NEMA).

Both standards have several parts covering general principles, physical specifications and safety. Designations by IEC and ANSI standards do not entirely agree, although harmonization is in progress. Manufacturers further have their own systematic identification of cell types, so cross-reference tables are useful to identify equivalent types from different manufacturers.

Battery chemistry

The terminal voltage of a battery depends on the chemicals and materials used in its construction, and not on its physical size. For example, primary (non-rechargeable) alkaline batteries

, no longer common, had stable terminal voltages around 1.35 volts.

The full battery designation identifies not only the size, shape and terminal layout of the battery but also the chemistry (and therefore the voltage per cell). 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 of other electrochemical systems.

Non-standard brand-specific names

Manufacturers may assign proprietary 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. For example, British standard U series were often sold under manufacturer prefixes such as "C" "SP" "HP" etc.; Ever Ready sold "U2" (D) batteries as "SP2" (standard-duty zinc carbon) and "HP2" (heavy duty zinc chloride).

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.

Round batteries

These are all single-cell round batteries with height greater than their diameter. In zinc-carbon or alkaline types they produce around 1.5 volts per cell when fresh. Other types produce other voltages per cell (as low as 1.2 volts for rechargeable nickel-cadmium, up to around 3 volts for lithium/manganese dioxide). The cylindrical form has a positive nub terminal at the cap of the cell, and the negative terminal at the bottom of the can; the side of the can is not used as a terminal.

Less common batteries

These types are not as likely to be found in consumer applications and may be specialized for photographic, instrumentation or other purposes. Some cell sizes are used only as elements of multi-cell batteries.

Round single-cell

These are all single-cell round batteries with a height greater than their diameter. In carbon-zinc or alkaline types they produce around 1.5 volts per cell when fresh. Other types produce other voltages per cell (as low as 1.2 volts for rechargeable nickel-cadmium, up to around 3 volts for lithium/manganese dioxide). The cylindrical form has a positive nub terminal at the cap of the cell, and the negative terminal at the bottom of the can; the side of the can is not used as a terminal when these cells are sold as individual units for consumer use.

Lithium cells

Coin-shaped cells are thin compared to their diameter. The metal can is the positive terminal, and the cap is the negative terminal.

The IEC prefix "CR" denotes lithium manganese dioxide chemistry. Since LiMnO2 cells produce 3 volts there are no widely available alternate chemistries for a lithium coin battery. The "BR" prefix indicates a round lithium/carbon monofluoride cell. See lithium battery
Lithium battery
Lithium batteries are disposable batteries that have lithium metal or lithium compounds as an anode. Depending on the design and chemical compounds used, lithium cells can produce voltages from 1.5 V to about 3.7 V, over twice the voltage of an ordinary zinc–carbon battery or alkaline battery...

 for discussion of the different performance characteristics. One LiMnO2 cell can replace two alkaline or silver-oxide cells.

All these lithium cells are rated nominally 3 volts (on-load), with open circuit voltage about 3.6 volts. Manufacturers may have their own part numbers for IEC standard size cells. The capacity listed is for a constant resistance discharge down to 2.0 volts per cell.

Silver oxide and alkaline cells

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 prefix batteries are the silver oxide chemistry version of the alkaline AG prefix. Since there are no 'common' names beyond the AG designation, many vendors 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 and usually a flat discharge characteristic (constant voltage), while the voltage of an alkaline battery decreases with use; and alkaline batteries are cheaper than silver. The capacity of a silver battery may be twice that of an alkaline. For devices which require a steady voltage such as photographic light meter
Light meter
A light meter is a device used to measure the amount of light. In photography, a light meter is often used to determine the proper exposure for a photograph...

s and those which fail to operate below a certain voltage—some digital callipers do not work below 1.38V— a silver cell with flat discharge characteristic is indicated. Inexpensive devices are sometimes supplied fitted with alkaline batteries, though they would benefit from silver.

Round button cells have heights less than their diameter. The metal can is the positive terminal, and the cap is the negative terminal. Button cells are commonly used in electric watch
Watch
A watch is a small timepiece, typically worn either on the wrist or attached on a chain and carried in a pocket, with wristwatches being the most common type of watch used today.

, and novelties.

IEC designation numbers indicate the physical dimensions of the cell. For cells less than one centimeter in height, the hundreds digits are the diameter in millimeters, while the last two digits are the height in tenths of millimeters. Taller cells get five digit numbers where the thousands digits are the diameter in millimeters, and the last three digits are the height in tenths of millimeters.

Sizes are shown for the silver-oxide IEC number; types and capacity are identified as (L) for alkaline and (S) for silver-oxide. In some cases, sizes which originally were distinct are now considered interchangeable. E.g., the 189/389 cell is 3.1 mm high and was designated 1131, while the 190/390 size is 3.0 mm high and was designated 1130, but these sizes are no longer distinguished.

Round lithium-ion rechargeable

Lithium-ion rechargeable batteries are not interchangeable with primary types with different chemistry. Lithium-ion cells are made in various sizes, usually made into packs for portable equipment. All of these cylindrical cells have a nominal voltage around 3.7 volts, and have a positive terminal nub at one end and flat negative terminal at the other. Many types are available with an internal protection circuit to prevent over-discharge and short-circuit damage. Safe and economic recharging requires use of chargers specified for these cells. Popular applications include laptop battery packs and flashlight
