When it comes to coin cell batteries, you have two options to choose from: CR2032 and CR2450. Both are lithium coin cell batteries that most people tend to assume that they are the same. This is because they belong to the same family of batteries. n reality, these two have significant differences that you should know about.   Even if you carefully analyze them, you will be able to tell that they have different physical dimensions.

Whether you are planning to buy CR2032 or CR2450, it is critical to know their differences. In this guide, we are going to do a complete breakdown of the differences between CR2032 vs. CR2450 batteries. By the end of this article, you will be in a perfect position to know which one is suitable for your application and business in general.

CR2032 overview

CR2032 is one of the most common batteries in the CR family of batteries. The 2032 on its name is derived from the fact that its diameter is 20mm while its height is 3.2mm.  The ‘CR’ designation means that it has a manganese dioxide chemical composition which is known for being stable and reliable.  It is a lithium coin battery, meaning that lithium makes up the main chemical composition of this battery.

CR2032 is widely used on small electronic devices such as watches, remote controls, key fobs, medical devices, calculators, fitness trackers, and computer motherboards, among many other devices that need a reliable power source.

CR2032 batteries are designed to supply adequate power to devices that have moderate power requirements. By this, we are referring to devices that don’t require extremely high voltage or high current to run. Similarly, it is not an ideal battery for devices that require an extremely low power supply. CR2032 batteries are widely available in the market and this stems from their high demand and application areas.

CR2450 Overview

CR2450 is a lithium coin battery that belongs to the CR family of batteries. This means that its chemical composition is lithium manganese dioxide.. The 2450 denotes its physical dimension which is 24mm diameter and 50mm height.

CR245 batteries are widely used in small electronic devices and appliances. They include calculators, watches, medical devices, remote controls, wearable devices, and fitness trackers among many others. They are suitable for small devices that are reliable sources of power to run for extended periods.

When it comes to performance, CR2450 tends to be quite reliable. They have a relatively higher capacity than most lithium coin batteries in the same category. This gives them an upper hand when it comes to battery lifespan. In case you have a powerful device that needs a reliable source of power, the CR2450 may be an ideal lithium coin battery for you.

CR2032 vs CR2450: Technical specifications

To start us off, let’s compare the technical specifications of these two batteries. They will give you a better insight into what you should expect between them. After all, the performance of a battery will always depend on its technical specifications.

CR2032 vs CR2450 Chemical composition

CR2032 and CR2450 have the same chemical composition. Both are made of lithium manganese dioxide. This is one of the most preferred chemical compositions that are used on coin batteries. It is known for having high energy density, meaning that the battery has the full capacity to store adequate amounts of energy. The chemical is also lightweight hence suitable for small and compact devices.

So, when it comes to chemical composition, both CR2032 and CR2450 are capable of delivering the same level of performance. This means that other factors will account for their differences in performance.

CR2032 vs CR2450: Physical dimensions

From their names, you can easily tell that the two batteries come in different dimensions. Generally, CR2450 is larger than CR2032. This means that the two cannot fit into one compartment. The difference in size also implies that CR2450 can store more chemical content than the CR2032. So, whenever you are buying either of these batteries, you should pay attention to the size of your battery compartment. You don’t want to end up with a battery that will not fit into your device.

CR2032 vs CR2450: Energy density

Since both have the same chemical composition, (lithium manganese dioxide) their energy density is almost within the same spectrum. However, their sizes dictate the differences in their energy density. Since CR2450 has a relatively larger size, its energy density is higher than that of the CR2032 battery. It has packed more energy in it. This property gives it a longer battery life. It is also more suitable for running devices that need higher battery capacity.

CR2032 vs CR2450: Voltage

Both the batteries have a nominal voltage of 3 volts. This means that both are fully capable of supplying the power that is needed for the relevant application. Given their similarity in chemical composition, the voltage of these two batteries is consistent.

CR2032 vs CR2450: Capacity

Here, we are referring to the current capacity of the batteries. CR2450 has a higher capacity than the CR2032. This means that if you have a power-hungry device or application, the CR2450 will be your best bet. However, this does not mean that CR2032 has a small capacity. It has a moderate capacity that will power a good number of devices that have a moderate power consumption rate.

CR2032 vs CR2450: Lifespan

Which one will last for long when used in any application? The CR2450 has a longer lifespan than the CR2032. This mainly stems from the fact that it has a higher current capacity. It will run your device for a longer period than the CR2032 before its power depletes. On the other hand, the CR2032  is still capable of delivering moderate performance in terms of lifespan.

In terms of shelf life, both the batteries have a good shelf life. They can be stored for a long without getting damaged, even if they are not in use.

CR2032 vs CR2450: Equivalents

Since both batteries have a nominal voltage of 3 volts, all their alternatives should have the same voltage. However, there is more to look at than the voltage of the battery. One of them is the capacity. The alternatives should have the same capacities. Another issue is size or dimension. Any other battery that is to be used as an alternative should have the same physical dimension.

The most common alternatives to the CR2032  battery include CR2032H, BR2032, DL2032,EC2032, and KCR2032.

The equivalents to the CR2450 battery include CR2450H,BR2450, DL2450,ECR2450 and KCR2450.

CR2032 vs CR2450: Cost

Given the specifications of the two lithium coin cell batteries, we can easily conclude that CR2450 is the most expensive of the two. Since it has a higher current capacity, it is capable of delivering better performance than the CR2032 battery. This implies that in case you are looking for an affordable option, CR2032 will be your ideal choice.

However, there is more to consider regarding the cost of the batteries. It will always be better to pay more for a better performance. Also,  given that CR2450 has a longer lifespan, it will be a better option than the CR2032.

Where you buy will also determine how much you will pay for the battery. Always source from reputable distributors as this will ensure you get the batteries at reasonable costs. You can get better prices by buying lithium coin batteries in bulk.

CR2032 vs CR2450: Applications

Both CR2032 and CR2450 are used for powering small electronic devices such as calculators, watches, toys, remote controls, and car key fobs, among others. However, the differences will be in the specifications of an individual device. Some devices have high-power specifications and can only be powered by the CR2450 and not CR2032. 

Conclusion

Well, from this guide, the differences between CR2032 and CR2450 are quite clear. CR2045 batteries are slightly larger in terms of their physical dimensions and also have higher current capacity. They are more suitable for devices that need more power to run. On the other hand, CR2032 batteries are relatively smaller in size and also have a lower current capacity than the CR2045. They are suitable for applications and gadgets that have lower demands.

Now that you know the differences, I hope that you can make a smart decision on which of these two lithium coin batteries is suitable for you.
