Practically every device you see is powered by something– a battery. No matter whether it is rechargeable or non-rechargeable, as long as it does what it is anticipated to do. Before making use of a device, what you require to examine together with various other functions is the kind of battery it utilizes. There are different sorts of batteries, as well as it wouldn’t be fair if you had actually bought the incorrect kind.
One of the several kinds of batteries is the Button/Coin Cell Battery. It is a non-rechargeable battery often used for remote controls, auto keys, medical equipment, hearing aids, etc. Likewise, there are different kinds of Button/Coin Cell Batteries relying on the chemical parts– Silver-Oxide, Mercury-Oxide, Alkaline, Zinc-air, etc.
Currently, you do not go ahead to choose any kind of switch cell battery without checking some elements. One of these aspects is the watch battery cross recommendation graph, OR Button Cell Battery Graph, as well as Dimensions. After you have to have experienced the chart, then you need to check out models as well as manufacturers.
This article intends to define the different sorts of button cell batteries together with charts for total understanding.
What are the Different Types of Button Cell Batteries?
As mentioned earlier above, the different types of coin cell batteries include Alkaline, Mercury Oxide, Zinc Air, and Silver Oxide.
- Alkaline Button Cell Battery
Among the least expensive and also most trusted coin cell batteries, you might ever before utilize is the alkaline battery. It is an excellent choice for digital devices that eat low voltage. It has a small ability of 1.5 v, making it go down continually as it is utilized. It better has a complete capability varying between 110-130mAh to do wonderfully.
Alkaline Coin Cell Battery is noted by LR ##, AG ##, and LR ####. Lastly, it has a shelf life below 5 years.
- Mercury Oxide Button Cell Battery
Mercury Oxide Button Cell Battery is another type; however, you may not find it too often. The reason is that it contains Mercury, an element believed to be responsible for many environmental hazards. The battery, following its design, has a low voltage but its capacity is quite good, i.e., 1.35v, and 180-200mAh. With the reality of its disuse, it is a little difficult to predict its shelf life.
| Button Cell Battery Types | Voltage (V) | Capacity (mAh) | Shelf Life (Years) | Labels |
| Alkaline | 1.5 | 110-130 | 5 | LR##, AG##, and LR####. |
| Mercury Oxide | 1.35 | 180-200 | 2-5 | MR##, MR#### |
| Silver Oxide | 1.55 | 150-200 | 10+ | SR##, SR####, or AG##. |
| Zinc Air | 1.4 – 1.45 | 600-700 | 4 to 5 | PR##, P###, and Z### |
- Silver Oxide Button Cell Battery
Another famous type of button cell battery is the Silver Oxide. It is affordable and promises long-term use with a shelf life of over 10 years. This battery has a good nominal voltage that makes it perfect for operating several mini devices. It also has a large capacity between 150 to 200mAh for an excellent performance. Additionally, Silver Oxide alkaline cell batteries are marked by SR##, SR####, or AG##.
- Zinc Air Button Cell Battery
The last coin cell battery is the Zinc-Air. It combines Zinc elements with natural air from oxygen for operation. It is an ideal choice of battery for hearing aids, and other mini devices. It has a good voltage, slightly higher than those for Alkaline, with a good capacity (600-700mAh) for performance. However, the shelf life is between the range of 4 to 5 years.
What is the Type Designation?
The Type of Classification is the alphanumeric coding system utilized for watch batteries. It is likewise called the International Criterion IEC 60086-3. Each maker has its Kind Designation/naming system. Now, this suggests switch cell batteries are not left out. For instance, a coin battery like LR1154 has its Kind Classification as AG13, LR44, A76.
The calling system is substantiated of 3 variables– Electrochemical System, Bundle Size, Letter Suffix.
Electrochemical System
Out of all the letter codes, the L, S, and also C kind cells are one of the most preferred; they are used in watches, calculators, computer clocks, etc. On the other hand, P-type cells are just valuable in listening to aids and various other medical equipment.
| Letter Code | Name | Cathode | Anode | Electrolyte |
| L | Alkaline | Manganese Oxide | Zinc | Alkali |
| S | Silver | Silver Oxide | Zinc | Alkali |
| P | Zinc Air | Oxygen | Zinc | Alkali |
| C | Lithium | Manganese Oxide | Lithium | Organic |
| M, N | Mercury | Mercuric Oxide | Zinc | Alkali |
Package Size
The other factor used in naming coin cell batteries is the package size. It is represented by a 2-digit code or 3- to 4-digit code. If it comes as a 2-digit code, then it describes the standard case size; however, a 3- to 4-digit code represents diameter and height.
The diameter codes are quite specific, i.e., the nominal diameter has a specific measurement (in mm) following its number code. Check the table below.
| Number Code | Nominal Diameter (in mm) |
| 4 | 4.8 |
| 5 | 5.8 |
| 6 | 6.8 |
| 7 | 7.9 |
| 9 | 9.5 |
| 10 | 10.0 |
| 11 | 11.6 |
| 12 | 12.5 |
| 16 | 16.0 |
| 20 | 20.0 |
| 23 | 23.0 |
| 24 | 24.5 |
| 44 | 5.4 |
Therefore, if you have:
Cr2032 – Lithium Type; 20mm Diameter; 3.2mm Height
LIR2032 – Alkaline Type; 20mm Diameter; 3.2mm Height
Letter Suffix
The extra letters that are found in the Type Designation represent the type of electrolyte.
Are Coin Cell Batteries Expensive?
Switch Cell Batteries are light, high-density non-reusable batteries that use great advantages for a great duration. They have an excellent cell voltage with amazing shelf life, making them suitable for different purposes. A lot more importantly, they are budget-friendly no matter the manufacturer. For instance, you can get a Cr2032 battery for much less (regarding $0.40)
Depending upon the maker, you may find device dimensions, i.e., amount in the pack. Therefore, while being inexpensive, you have the opportunity to utilize as much as you can over a period.
Conclusion
With this article on Button Cell Battery Chart and Sizes, it is obvious that coin cell batteries are quite different from themselves. You must now have to selectively choose what is perfect for the device involved – it shouldn’t be so difficult.
