The complete nomenclature for a battery specifies size, chemistry, terminal arrangement, and special characteristics. The same physically interchangeable cell size or battery size may have widely different characteristics; physical interchangeability is not the sole factor in substituting a battery.[1]
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) and the number of cells in the battery. For example, a CR123 battery is always LiMnO2 ('Lithium') chemistry, in addition to its unique size.
The IEC prefix "CR" denotes lithium manganese dioxide chemistry. Since LiMnO2 cells produce 3 volts there are no widely available alternative chemistries for a lithium coin battery. The "BR" prefix indicates a round lithium/carbon monofluoride cell. See lithium battery for discussion of the different performance characteristics. One LiMnO2 cell can replace two alkaline or silver-oxide cells.
IEC designation numbers indicate the physical dimensions of the cylindrical cell. Cells less than one centimeter in height are assigned four-digit numbers, where the first two digits are the diameter in millimeters, while the last two digits are the height in tenths of millimeters. Taller cells are assigned five-digit numbers, where the first two digits are the diameter in millimeters, followed by the last three digits indicating the height in tenths of millimeters.
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.[144]
In the following table, sizes are shown for the silver-oxide IEC number; types and capacity are identified as "(L)" for alkaline, "(M)" for mercury (no longer manufactured), and "(S)" for silver-oxide. Some sizes may be interchangeably used in battery holders. For example, 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 a battery holder will accept either size.
Miniature zinc-air batteries are button cells that use oxygen in air as a reactant and have very high capacity for their size. Each cell needs around 1 cm3 of air per minute at a 10 mA discharge rate. These cells are commonly used in hearing aids. A sealing tab keeps air out of the cell in storage; a few weeks after breaking the seal the electrolyte will dry out and the battery becomes unusable, regardless of use. Nominal voltage on discharge is 1.2 V.
Lithium-ion rechargeable batteries are generally not interchangeable with primary types using a different chemistry, due to their higher voltage. Many are also available with protection circuits that can increase their physical length; for example, an 18650 is around 65 mm (2.56 in) long, but may be around 68 mm (2.68 in) long with a protection circuit. Some such circuits increase cell diameter instead. The increased dimensions may mean the cell will no longer fit in battery compartments intended for cells without such circuitry.
Commonly-used designation numbers indicate the physical dimensions of the cylindrical cell, as given in IEC standard 60086-1 for cylindrical primary cells. The first two digits are the nominal diameter of the cell in millimetres, and the two following digits are generally the height in millimeters, with the fifth digit indicating cylindrical shape. Alternately, the last three digits can refer to the height in tenths of a millimeter. Manufacturers may use non-IEC designations for their products.
The PP (Power Pack) series was manufactured by Ever Ready in the UK (Eveready in the US). The series comprised multi-cell carbon-zinc batteries used for portable electronic devices. Most sizes are uncommon today; however, the PP3 size (and to a lesser extent PP8, used in electric fencing, and PP9) is readily available.[246] The PP4 was cylindrical; all the other types were rectangular. Most had snap terminals as seen on the common PP3 type. These came in two incompatible sizes, as is evident in some of the pictures below, those on larger, mostly older, battery types such as the PP9 being somewhat larger than those on the smaller batteries such as the PP3.

Different battery sizes contribute to the overall effectiveness of your equipment, but it is important to understand why. Generally, the larger the battery is, the more capacity it has for energy storage. So even though a big and small battery are both rated at 1.5V, the big battery stores more energy and provides a longer battery life. Batteries are extremely useful to us as consumers because they convert stored chemical energy into electrical energy, eliminating the need for a direct power source.
Many automatic hand sanitizer dispensers require the use of these 1.5V batteries. Perfect for heavy-duty applications where batteries require frequent use, you can be sure that your device is operating with safe, reliable power. These batteries are also frequently used in restrooms that utilize battery powered flush sensors.
9V batteries work extremely well for devices like infrared thermometers, battery powered temperature alarms, and electronic portion scales. These products may all encounter extreme temperatures from food, walk-in coolers, or other kitchen equipment. 9V batteries are exceptionally durable and offer outstanding performance, working in environments from 0 to 130 degrees Fahrenheit.
At 3 volts, the CR2032 battery is commonly used in watches, calculators, toys, and different medical devices. These batteries provide long-lasting, reliable power and have a very high weight-to-power ratio. Used in wrist watches and slim, compact thermometers, this battery is practically weightless while providing hours of use.
When choosing batteries, there are lots of things to consider. Different chemical constructions offer unique benefits depending on where the battery is being used. Outlined below are common battery types, along with the pros and cons of each.
Lithium batteries are one of the most commonly used battery types. They offer the highest energy density of any other battery cell, meaning they store more energy than other batteries, such as alkaline. Lithium batteries are only sold in AA, AAA, and 9V sizes; however, their mAh ratings exceed every other non-rechargeable battery. One AA lithium battery ranges from 2,700-3,400 mAh, and will last a long time, even under heavy-use.
Alkaline batteries are economical, easy to dispose of, and extremely popular. They normally have a capacity rating of over 2,500 mAh, great for moderate to heavy-use devices. Unlike lithium batteries, almost every standard size battery offers an alkaline construction, making it perfect for most devices.
Silver oxide batteries are commonly used in wrist watches and other small devices. Because the battery is constructed of real silver, it is often sold only in button cells where the amount of silver is insignificant to the overall cost of the product.
Zinc air batteries are unique in their construction, as they generate electrical power through exposure to oxygen. This makes them unfit for wrist watches, but perfect for hearing aids. Activating the battery requires a user to remove a sealing tab from the battery, enabling airflow.
Although NiMH batteries are labeled as high-density, this can come at the expense of a reduced cycle life. They have a high energy density, but can only be recharged about 500 times. While they will certainly pay for themselves over time, they may not be the best choice for applications like smoke alarms, TV remotes, or clocks. All of these devices draw very low energy, and a NiMH battery is best used within a 30-day period. Like NiCd batteries, NiMH batteries will deliver at full capacity until almost all of the energy has been discharged.
Large, block-shaped, and heavy, this battery provides hundreds of amps of electrical current and is commonly used in cars and other industrial equipment. Compared to some of the bigger voltage batteries, it might not make sense that a car is able to function with only 12 volts while other heavy equipment requires much more than just 12 volts. This is because heavy equipment and cordless power tools all require a charge after their energy has been depleted. Cars use an alternator which acts as a generator to keep the car's battery powered, eliminating the need for an external charger.
At 22 volts, this battery is used to power heavy equipment and high-power cordless tools like drills and electric saws. Because cordless power tools are compact, but require a great deal of energy, 22V batteries are perfect for the job. They deliver high power for an extended period of time, such as when installing electrical appliances.
