What is a CR1220 Battery?

Are you looking for the right battery for your electronic device? Perhaps this time you should consider getting a CR1220 battery. It's one of the most common coin cell batteries that are used for a wide range of applications, especially in modern electronics.

CR1220  is a lithium manganese dioxide coin cell battery that is designed to meet the IEC standards for batteries.

In this standard and nomenclature, the ‘C’  denotes the chemical composition of the battery, which is lithium metal that serves as a negative electrode while the manganese dioxide serves as a positive electrode.

The ‘R’ on the name denotes that the battery has a cylindrical shape. This applies to all other cylindrical battery types. For example, the square-shaped batteries will have the “F” letter.

The ‘12’ stands for the diameter of the battery, which in this case is 12.5mm.  The ‘20’ stands for the height of the battery, which is 20mm.

CR1220 is used in most digital products where it serves as CMOS. However, it is still used as the main power source in some application areas. As a CMOS, it is mainly used for controlling the memory modules.

Keep reading as we get deeper into everything that you should know about CR1220. By the end of this guide, you will be in a perfect place to buy and choose the best CR1220 batteries from reliable suppliers and distributors.

CR1220 Specifications

Here is a summary of the CR1220 battery specifications

· Chemical composition: Lithium/Manganese dioxide (Li/Mn02)

· Positive electrode: Manganese dioxide

· Negative electrode Lithium

· Diameter: 12.5mm

· Height: 2.0mm

· Nominal voltage 3.0V

· Rated Capacity 40mAh

Even as you pay attention to these specifications,  you should keep in mind that the exact figures may vary depending on the manufacturer. Additionally, confirm the power requirements of your products and the specifications of the battery. Ensure that they are compatible. 

Features and advantages of CR1220 batteries

Here are some of the notable features of CR1220 batteries that you should know:

· High voltage: With a nominal voltage of 3V, the battery provides adequate energy to power different devices.

· The battery has a very low self-discharge rate, a key factor that contributes to its reliability

· High weight-to-power ratio. Supplies more power despite being lightweight

·  Suitable for a wide range of applications

· Stable performance in different temperature ranges

· High voltage stability: The battery is designed to maintain constant and stable voltage for an extended period.

What are the limitations of the CR1220 battery?

 Power capacity is one of the biggest limitations of the CR1220 battery. With a voltage rating of 3V, it cannot be used in applications with higher power requirements.

CR1220 batteries are not rechargeable. Once it depletes its capacity, you will have to dispose of them.

CR1220 battery equivalent

When it comes to choosing and using coin cell batteries, there is always an allure of getting alternatives. So, what are the perfect alternatives to the CR1220 battery?

As we have seen from the specs,  CR1220 measures 12mm and 2.0mm. This alone implies that the alternative batteries should have the same dimensions. Once you have confirmed the size factor, the next thing is power requirements and specifications.

Here are some of the most common CR1220 alternatives:

· DL1220: This is also a lithium-ion coin cell battery that has the same specifications as the CR1220 battery. It also has a nominal voltage of 3V and its dimensions are similar to the CR1220.

· Energizer ECR1220: Manufactured by  Energizer, this is another lithium-based battery that you can use in place of the CR1220.

· BR1220: BR is a non-rechargeable battery that you can also use in the place of CR1220 battery

· SB-T13 battery: This lithium battery is manufactured by different brands including Duracell. It is an ideal equivalent of the CR1220.

Applications of CR1220 batteries

Given their size and properties, here are some of the most common applications of CR1220 batteries:

· Electronic toys: These batteries have sufficient energy to power most electronic toys in the market. It can power functions such as lighting and even mechanical forces that are needed in these toys

· Car keyless entry systems

· Calculators

· Glucose monitors: These are devices used for testing the level of blood sugar. The small sizes of these batteries make it possible to do so. Other than the primary functionality, the battery can even power the display unit.

· Cardiac pacemakers

· Hear-rate monitors

· Memory backup devices

· Electronic watches

What kind of application or product are you building? In case it will require a reliable coin cell battery, then you should consider choosing CR1220 batteries.

CR1220 Manufacturers
