List of battery sizes



 

Additional recommended knowledge

Contents

This article refers to common battery types and sizes in household and light industrial use.

Battery 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.

Battery chemistry

Older batteries were mostly based on rechargeable lead-acid or non-rechargeable alkaline chemistries, with nominal voltages in increments of 1.5 Volts, each representing one individual electrochemical cell.

New battery chemistries have strained older naming conventions. Rechargeable NiCd and NiMH typically output 1.25 V per cell. Some devices may not operate properly with these cells, given the 16% reduction in voltage, but most modern ones handle them well. Conversely, lithium-ion rechargeable batteries output 3.7 V per cell, 23% higher than a pair of alkaline cells (3 V), which they are often designed to replace. Non-rechargeable lithium-chemistry batteries, which provide exceptionally high energy density, produce about 1.5 V per cell and are thus similar to alkaline batteries.

Many new battery sizes refer to both the batteries' size and chemistry, while older names do not. For a more complete list see battery types. This summary is only for types relating to battery "sizes".

Primary battery chemistries

(in order of increasing energy density)
Chemistry Cell
Voltage
Comments
Zinc–carbon 1.5 Inexpensive.
Zinc chloride 1.5 Also known as "heavy duty", inexpensive.
alkaline
(zinc–manganese dioxide)
1.5 Moderate energy density.
Good for high and low drain uses.
oxy nickle hydroxide
(zinc-manganese dioxide/oxy nickel hydroxide)
1.7 Moderate energy density.
Good for high drain uses
Lithium
(lithium–copper oxide)
Li–CuO
1.5 End of life.
SR battery is used instead now.
Lithium
(lithium–iron disulfide)
LiFeS2
1.5 Expensive.
Used in 'plus' or 'extra' batteries.
Lithium
(lithium–manganese dioxide)
LiMnO2
3.0 Expensive.
Only used in high-drain devices or for long shelf life due to very low rate of self discharge.
'Lithium' alone usually refers to this type of chemistry.
Mercury oxide 1.35 High drain and constant voltage.
Banned in most countries because of health concerns.
Zinc–air 1.35–1.65 Mostly used in hearing aids.
Silver oxide (silver-zinc) 1.55 Very expensive.
Only used commercially in 'button' cells.

Rechargeable battery chemistries

(in order of increasing energy density)
Chemistry Cell
Voltage
Comments
NiCd 1.2 Inexpensive.
High/low drain, moderate energy density.
Moderate rate of self discharge.
Suffers from memory effect (which sometimes causes early failure)
Lead Acid 2.2 Moderately expensive.
High/low drain, moderate energy density.
Moderate rate of self discharge.
Suffers from no memory effect
Common use - Automobile batteries
NiMH 1.2 Expensive. Useful in high drain devices.
Traditional chemistry has high energy density, but also a high rate of self-discharge.
Newer chemistry has low self-discharge rate, but also a ~25% lower energy density.
Lithium ion 3.6 Very expensive.
Very high energy density.
Not usually available in "common" battery sizes (but see RCR-V3 for a counter-example).
Very common in laptop computers, moderate to high-end digital cameras and camcorders, and cellphones.
Very low rate of self discharge.
Loses 5%-10% of its storage capacity every year from the time of manufacture whether it's used or not.
Volatile: Chance of explosion if short circuited, allowed to overheat, or not manufactured with rigorous quality standards.

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 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 purposefully 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.

Naming notes

  • SR# / LR# / AG# 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. 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, key chain flashlights, or laser pointers the LR type is preferred. [There seems to be a contradiction here; are you sure it shouldn't be SR instead of LR?] 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.
  • Button / Coin / Miniature: In many places these are used interchangeably.
