CR2032 Battery Guide: Everything You Need to Know

Do you own a key fob, watch, or remote-control toy? You may have noticed that all these devices have a similar battery type. The label on these batteries shows the number CR2032.
The number CR2032 denotes a battery type and size you should get if you need a replacement. We want to look at the CR2032 battery in more detail, its components, uses, features, and what makes it a good pick, depending on the application.

What is a CR2032 Battery

The CR2032 batteries are non-rechargeable coin-cell batteries that use lithium chemistry technology to power the devices. Lithium chemistry makes the batteries offer more power for their size, reliability, and affordability.

Features

The features can be a determining factor in whether you have to look for the CR2032 battery in nearby stores or buy it online. The features make you see how versatile the battery is in various applications we handle daily.
1. The 3V CR2032 coin cell battery is lightweight, making it an easy choice for small devices. It is still high-voltage and high-energy density.
2. The CR2032 lithium battery stands out for its stable discharge characteristics. This makes it ideal for precision devices that need stable voltage even when the battery discharges over time.
3. An operating temperature of -20 to 60 degrees Celsius makes it stable for most operations. For example, it is highly unlikely that a watch would reach the 60-degree mark while working.
4. The CR2032 battery is less likely to leak. The leakage resistance gives the battery more applications as you are not worried about it leaking or exploding.
5. Reliability also makes the CR2032 3V watch battery a great purchase. You could still use it in other compatible devices. Such a battery is expected to last up to 10 years in storage. Depending on the device’s power needs, expect a lifespan of 3 to 10 years.

Applications

The chances that you’ll need a CR2032 lithium battery are high because of its compatibility with many devices we own today. So, what are the applications of this battery?
The CR2032 battery is commonly used in:
-Medical equipment
-Computer systems
-Watches
-Electronic keys or key fobs
-Remote controls
-Toys
-LED lights
-Garage door openers
-Pet collars, etc.
The list can go on. Simply look at the battery already inside the device. If it is marked CR2032, replacing it with an equivalent battery should be easy.

CR2032 Battery Specifications

Below are the expected CR2032 battery specifications. This might vary slightly with the manufacturer.

CR2032 Battery Structure

The lithium battery CR2032 has the same outside structure as any other battery type, with positive and negative cases.
The positive case is larger than the negative case. It also has a positive sign imprinted on it, making it easier to identify.
The negative case has a mesh structure compared to the positive case. Other components include a space, spring, and separator. The picture above gives you a more detailed look at the battery structure of the CR2032 key fob battery.

CR2032 Battery Lifespan

You might be considering the battery lifespan before getting the CR2032 battery from Target. The CR2032 button cell battery has an average lifespan of 3 to 10 years, depending on the device. Some devices need more power, while others not so much.
Other than the current draw or power usage of the device, there are other things that could determine the lifespan of the Duracell CR2032 battery. Such include:
1. The operating temperature of the lithium CR2032 battery can be a big influence on the lifespan. Constantly operating or storing at high temperatures can shorten the overall battery life.
2. It might not seem important, but the overall quality of the battery can determine its durability and reliability. Buying from top brands such as Duracell and Panasonic guarantees a longer lifespan.
3. How you store the CR2032 button cell battery package can influence its durability. Most manufacturers recommend storing the batteries away from extreme temperatures and humidity to extend the battery’s lifespan.
4. The battery’s age could also be a factor. Batteries degrade over time, and this is natural. So, check the manufacture date to avoid buying older batteries, which might have discharged slowly over time.

How the CR2032 Battery Compares to Other Coin Cell Batteries

Choosing the CR2032 battery for a key fob or any other device that uses such a battery size is often an easy pick because of its performance, reliability, and long shelf life. However, how does it compare to the other coin cell batteries?
You can expect a couple of similarities between the CR2032 battery and other coin cell batteries.
The first one is that these batteries use the same lithium technology. This allows them to have a higher energy density and good performance in cold environments.
The voltage of most coin cell batteries with lithium chemistry is 3V.
As for the size, there can be differences, but the CR2032 battery is the most common compared to the others, such as the CR2016 battery. A slightly larger size means more capacity.
The LiR2032 battery has a higher capacity of 3.2 to 3.9V compared to the CR2032 battery. So, if you need more power, you should always consider the LiR2032 batteries.
Another difference is that the LiR2032 battery is rechargeable, while the CR2032 is primarily not rechargeable.
The other potential choice is the LR44 battery, which has a lower voltage and capacity than the CR2032.
As you can see, the button cell batteries will have differences and similarities. What is crucial is to understand your needs and pick the right one.

CR2032 Battery Usage Tips

You may want to consider doing a few things to keep the CR2032 batteries working as expected. Here are expert battery usage tips.
-Simple things such as proper installation can go a long way to keeping the battery operating as expected.
-The storage conditions also matter. Store these batteries in a cool dry place to prevent potential degradation.
-Avoid extreme operating temperatures for the batteries, as they affect their overall performance.
-Do not mix new and old batteries. The next time your device needs fresh batteries, replace all the batteries.
-Keep the used batteries out of reach of children. If they swallow it, seek medical attention.

Conclusion

The CR2032 battery is a good choice for many devices used daily. The next time you have to replace one, make sure it is from a top brand, and you will have an easy time enjoying several years of service. The price point, reliability, performance, and application variety make the CR2032 battery a must-have accessory in the house, as you never know when you might need it.
