Have you ever bought a battery and regretted it? Maybe, the battery could not fit into its designated compartment or its performance was underwhelming. For easy decision-making, most buyers prefer taking the route of comparing batteries from the same families.  It is through a comprehensive comparison that one will be able to conclude.

In this case, we will be comparing CR2025 vs CR2032  batteries. Both are button-cell batteries that tend to share features and even application areas. By the end of this guide, you will be in a perfect position to decide which is the right one for your application.

What is a CR2025 battery?

CR2025 is a lithium-based non-rechargeable coin cell battery that enjoys a significant level of popularity in the electronics market. It has a diameter of 20mm and a height/thickness of 2.5mm hence the name 2025.

CR2025 has a nominal voltage rating of 3 volts, enough to run most devices and appliances. Most CR2025 batteries have the capacity of 170mAh though the figures may vary depending on the manufacturer.

The physical dimensions of CR2025 batteries make them suitable for devices that have smaller mounting space than what CR2032 can fit in. Additionally, it has a lower energy capacity than the CR2032.

What is a CR2032 battery?

CR2025 is a non-rechargeable lithium coin or button cell battery that is designed to supply power to different devices and products.

 With a voltage rating of 3 volts, the battery has a diameter of 20mm and a thickness of 3.2mm hence the name 2032. Of course, the “CR” stands for the chemical composition of the battery which is lithium manganese dioxide. The ‘C’  implies that the battery has a cylindrical shape while the R means that it is a lithium cell.

CR2032  is also referred to using other names such as 2032,  5400LC, and BR2032, among other names. You can fit this lithium coin battery with the help of the connection which will allow you to place the battery into a device at any given position.

Despite having a compact size, CR2032 has an impressive battery capacity that allows it to power a device for extended periods without depleting its power.

Difference is size: CR2025 vs CR2032

This is one of the biggest differences between CR2025 and CR2032. From the specifications, it is clear that both have a diameter of 20mm.

However, the difference is in their thickness.  CR2032 is slightly thicker than CR2025 by 0.7mm. The difference is quite small and most devices are designed to accommodate both batteries without any problem. The only issue is the CR2032 may be more close-fitting in the battery compartment in case they are interchanged. 

Difference in capacity

CR2032 and CR2025 come in different capacities. The battery capacity of CR2025 ranges between 150mAh to 170mAh. On the other hand, the CR2032 is between 220mAh to 240mAh.

With this difference, it means that CR2032 is likely to serve its purpose for a long before it runs out of battery life. Let’s say in case of heavy usage, CR2032 will serve you for a period of between 3-4  months while CR2025 will serve you for a period of between 2-3 months under the same usage.

With this difference, it means that you should go for a CR2032 if you intend to have a battery that has a longer lifespan.

 The table below  gives a summary of the differences between CR2025 vsCR2032 batteries

CR2025 vs CR2032  similarities

 Despite the many differences, there are also some outstanding similarities between these two types of lithium-based coin cell batteries. They  include:

· Both have a nominal voltage of 3 volts

· Both have a diameter of 20 mm

· Both are lithium-ion batteries, meaning that they have the same chemical compound

· Both are non-rechargeable batteries

· They have almost the same shelf-life 

Can I use a CR2032  battery instead of a CR2032?

When it comes to battery comparison, the issue of interchangeability will always arise. In this case, we are trying to establish whether CR2032 and CR2025 are interchangeable.

Yes, you can use CR2032 instead of CR2025 and vice versa.  As we have seen from our comparisons, these two lithium-based batteries have more similarities than differences.

One of the differences is in terms of their capacities. CR2032 will definitely last longer than CR2025 in case of the exchange. This is because it has a higher battery capacity.

Dimension is always an issue when it comes to the interchangeability of lithium coin batteries. Even though there is a slight difference in their thickness, they can still fit into the same battery compartment. Alternatively, you can do some modifications such as folding a piece of aluminum foil on the compartment to take the space.

Summary

In conclusion, there are many similarities between CR2025 and CR2032., both physically and electrically.  They have the same diameter, voltage, chemical composition,  and application areas. The only difference is in terms of their thickness and current capacity.

So, which one should I choose between CR202 vs CR2032? Well, it all depends on the specifics of your application. With this comparison, it will be easy to decide on which is the right battery.

 Once you decide, the next step is to work on where to buy lithium button batteries.  Ensure that you get them from the right sources, that is if you are keen on the quality or you would like to buy lithium coin cell batteries in bulk.
