Battery CR2025 vs. CR2032: What’s The Difference?

Do you think the CR2025 and CR2032 look a little too much like each other? If yes, you’re not alone!

With a small round shape, these lithium-ion batteries confuse a lot of people regularly. Some people even fit these batteries into different gadgets – only to get disappointed when the error message pops up.

But is there really a difference between these lookalikes, and does it matter? Let’s explore the answer to these questions with this detailed battery CR2025 VS CR2032 comparison!

How to Read Battery Names?

Before we dive into details, we will first discuss what these battery names represent.

The letters CR are present in all lithium batteries. It shows there is lithium-based chemistry, whereas the R is for the round shape.

The first two numbers after it show the diameter of the batteries, and the last two numbers are for the thickness. Keep this important information in mind as we continue learning the differences between the two batteries!

What’s CR2025 Battery?

The CR2025 is a button lithium-based battery that has a 20mm diameter and 2.5mm thickness. It has a fairly high voltage of 3V and 170 mah capacity.

The 2.5mm thickness consumes little space and slides into battery ports easily. So you don’t need to worry about the device getting damaged. There are also no issues regarding device compatibility.

Since it’s not very thick, the CR2025 battery works for a wide range of products. These include calculators, toys, motherboards, LED lights, electronic games, and various medical devices like glucose monitors and tensiometers.

That said, the CR2025 battery doesn’t last very long. It will work for about a year or two in an active and frequently-used device. Meanwhile, it might work for 2 to 4 years in a moderately-used device. Only big companies promise a long lifespan of 10 years, but even then, there is no guarantee.

Some other popular names of this lithium coin battery include 5003LC, 280-205, DL2025, BR2025, ECR2025, AWI L12, and SB-T14. Most companies also add their name in front of the title, like Panasonic CR2025, Duracell DL2025, Maxell CR2025, and Energizer ECR2025.

What’s CR2032 Battery?

The CR2032 battery belongs to the same category as 2025. It’s a lithium button cell battery with a 20mm diameter. However, its thickness is 3.2mm.

Its thicker structure allows for a higher battery capacity of 240mAh. So, both the voltage output (3 volts) and battery capacity are excellent. You can use it on a huge number of gadgets, ranging from computer motherboards to weapon sighting systems.

CR2032 battery is also called 5004LC. Some people also call it BR2332, BR2032, AWI L14, and LF 1/2V. You’ll also come across company names attached with CR2032 to form a more complex and fancy term.

CR2025 VS CR2032: What’s the Difference?

Now that we have analyzed the basics. Let’s put the batteries side-by-side and compare them using 6-important features.


Both CR2025 and CR2032 are lithium cell batteries with the same diameter of 20mm. The only physical difference between them is the thickness.

The CR2032 battery is 0.7mm thicker than the CR2025. This increased thickness allows it to hold a higher charge capacity and thus supply power for a longer time duration.

However, it affects versatility too. The CR2025 battery is thin, which makes it suitable for a larger number of appliances than the CR2032. You can fit it in all-sized devices, even the small ones with limited mounting space.

Battery Capacity

Battery capacity refers to the total electrical output generated as a result of electrochemical reactions inside the battery. This electricity powers up the attached device. So, the higher the output, the longer the device will run.

For coin cell batteries, the average capacity is 150mAh to 170mAh. This means the CR2025 lies in the good battery capacity category with 170mAh. It can run the gadgets for a considerably long time.

Comparatively, CR2032 has a higher battery capacity of 240mAh. That’s a difference of 70mAh!


Another physical difference between the batteries is weight. The CR2025 battery weighs 2.6 grams, whereas the CR2032 battery weighs 3.0 grams.

Of course, the weight might differ slightly depending on the manufacturer. But the general difference between both of them is about 0.4 grams. So, CR2025 is a thinner battery.


The lifespan of a button cell battery depends on various different factors. These include material quality, temperature, storage conditions, and usage intensity.

Ideally, a high-quality button cell battery that is stored in a dry and cool place will last anywhere from 3 to 10 years. The average for lithium batteries is around 4 to 5 years.

However, if the usage is intense and frequent, the CR2025 battery will last 1 to 3 years. Meanwhile, the CR2032 battery can pull out a longer service life – thanks to its higher capacity.


As lithium cell batteries, both types are versatile and multi-purpose. It doesn’t matter whether they are big or small. You can install them on all kinds of devices like laser pens, wristwatches, fitness appliances, etc.

But, the CR2032 has certain limitations due to its thickness. You cannot use it in gadgets that have a small or thin mounting space.

For such gadgets, a CR2025 battery will work much better. It will slip in and out easily. Also, the gadget will remain safe and undamaged.

However, since the CR2032 has a higher battery capacity, you can use it for more powerful devices like hearing aids, LED lights, and security devices.


Button batteries come in individual packages. People can buy one or two depending on their requirements. This makes the battery generally expensive.

But, when shopping, you will observe that the CR2032 battery is slightly more expensive than the CR2025. It’s mainly because the battery has the potential to power larger devices.

So, Is CR2032 Better than CR2025?

The answer to this particular question is both yes and no. If judged on its overall features, the CR2032 comes with a better power-packed profile than the CR2025.

You get a higher battery capacity of 240mAh that’s capable of delivering powerful current to the load. Even if the battery doesn’t utilize its full potential, you will get a standard of 225mAh. Comparatively, the nominal for CR2025 is 160mAh.

So, the CR2032 is definitely a better option. However, its high battery capacity becomes pretty much useless if the 3.2mm thickness won’t let it fit in mounting space. In this case, the CR2025 proves to be a better choice.

This is why we always recommend users consider their purpose and needs before making a decision.


Are CR2025 and CR2032 batteries interchangeable?

Yes, CR2025 and CR2032 batteries are interchangeable. However, chances are that they won’t fit in certain mounting spaces.

While nothing can be done to fit a CR2032 in a small space, you can adjust a CR2025 in a bigger space using aluminum foil. Here’s how:

  • Cut a small piece of aluminum foil and fold it. It should fill the remaining space completely.
  • Put the foil on the positive terminal side of the battery. This will now serve as a conductor of charges.
  • Close the battery compartment tightly so that there’s good contact between the surfaces. The foil shouldn’t get displaced at all for proper functionality.

Are there any similarities between CR2025 and CR2032?

Yes, there are a lot of similarities between CR2025 and CR2032. These include:

  • Both are lithium-based button cells.
  • Both have a 20 mm diameter size.
  • Both are 3-volt lithium coin batteries.
  • Both operate in the same range of temperature, which is.30 to 60 degrees Celsius.
  • Both have the same discharge properties, like a self-discharging rate of 1%.

What battery can replace CR2032?

You can use CR2025 to replace a CR2032. But, you cannot use the CR2016 batteries. While they do have the same diameter of 20 mm, the difference in thickness is way too much.

Is CR2023 the same as CR2032?

Many people get confused between CR2023 and CR2032. Since they have the same digits in them, they appear as the same batteries. But that’s not true!

Earlier in the article, we discussed how to read lithium battery names. If we put that knowledge to the test, we can see that CR2032 is 0.9mm thicker than CR2023.


To sum up, the main differences between CR2025 and CR2032 are weight, thickness, battery capacity, lifespan, usability, and cost. All these factors help determine which lithium button battery is best for you.

We hope this detailed battery CR2025 VS CR2032 comparison has equipped you with all the necessary information to make the decision. If there’s still doubt, let us know in the Комментарии и мнения владельцев below!

CR2025 Vs CR2032 Battery: What Are The Differences Between?

Choosing the right battery for certain electronic devices is one of the most frequently asked questions by consumers, especially when it comes to the CR2025 vs CR2032. This is because these batteries come with many similar characteristics.

Even though all batteries have similar functions, there are some obvious differences that you need to keep in mind when shopping.

We’ll look through the appearance, features, and performance of these batteries. In addition, we will discuss specific battery manufacturers to help you understand the applications of these batteries.

Difference Between The CR2025 Vs CR2032 Battery

Chemistry is indicated by the letter “C” in the name. The circle and the coin are referred to by the letter “R.” The International Electrotechnical Commission has issued these rules (IEC).

The first two digits of the number, such as CR2025 or CR2032, indicate their size is 20 mm, while the latter represents the height or thickness. In this case, the 2032 battery is 3.2 mm thick, while the 2025 battery is 2.5 mm thick.

The CR2025 Battery

The CR2025 is a lithium primary, non-rechargeable coin cell battery that is 20 mm in diameter and 2.5 mm thick. It is 3V high voltage, and depending on the manufacturer’s specifications, the capacity can be up to 170mAh.

Compared with items using CR2032, the CR2025 is very easy to buy because it is less expensive. These batteries’ low capacity and long lifespan account for their low cost. Since it only weighs 2.6 grams, these batteries are relatively lightweight.

CR2025 is somewhat more suitable when used in places with less installation space due to its lower thickness. On the other hand, when used in the same applications, the lower capacity (mAh) of the CR2025 will lead to a slightly shorter lifespan than the CR2032.

Also, the CR2025 is named as 280-205, BR2025, 5003LC, ECR2025, DL2025, SB-T14, Citizen 280-205, AWI L12, ElectroChem 3B980, Duracell DL2025, Eveready CR2025, Energizer ECR2025, Fuji CR2025, Kodak KCR2025, I.E.C. CR2025, Maxell CR2025, Panasonic CR2025, NEDA 5003LC, RadioShack CS0155, RadioShack UBATL0006TAZZ, RadioShack CS1005, Rayovac KE-CR2025, Sanyo CR2025, Saft LM2025, Seiko SBT14, Toshiba CR2025, Sony CR2025, Varta CR2025, or 2025.


Since CR2025 batteries are sometimes used in most car keys, they can last only about 3 or 4 years before needing to be replaced. The battery life for a more power-hungry gadget will be a lot shorter. For example, the battery life in an IoT tracker that enables real-time object tracking is only about a year.

This slightly shorter service life can be attributed to the smaller CR2025 capacity.

Ideally, the CR2025 should be manufactured with high-quality materials and kept dry. When properly stored, our lithium coin batteries have a shelf life of up to 8 or 10 years.


Similar to the CR2032, the CR2025 is a very popular lithium coin cell battery used in similar quantities and for equivalent purposes.

CR2032 batteries are an excellent choice for many applications due to their small size, relatively large capacity, long life, and stable discharge capacity.

Also, the CR2032 is named 2032, AWI L14, 5004LC, BR2032, CR2032, BR2332, EA2032C, DL2032, L2032, ECR2032, LF1/2V, RFA-35, LM2032, or Seiko SB-T15.


Several factors, such as storage conditions, material quality, storage time, physical impact, humidity, or temperature, can affect the battery’s storage time.

The application will have a great influence on the service life. It is rare to use CR2032 batteries for car keys, but they can last up to 4 or 5 years without replacement. Some more power-hungry devices, like the Apple Air Tag, force the battery to work continuously to track the subject, giving the CR2032 a life span of just one year.


The CR2032 lithium coin cell battery is currently used in many commercial applications, including motherboards, security system boards, and weapon aiming systems. In addition, the CR2032 can be equipped with connection tabs that allow the battery to be inserted in any required position.

A few specific applications of CR2032 are: Computer motherboards, watches, PDAs, calculators, electronic organizers, toys, garage door openers, games, pet collars, door chimes, LED lights, pedometers, sporting goods, calorie counters, medical devices, stopwatches, etc.

Strong goods, such as LED lights, hearing aids, screen scanners, etc., are more suitable for CR2032 batteries with a high capacity of 235 mAh.

Technical Specifications

  • Classification: Lithium Coin
  • Chemical System: Manganese Dioxide/Lithium
  • Self Discharge: ~1% / year
  • Capacity: ≈235 mAh
  • Nominal Voltage: 3 Volts
  • Operating Temperature: 0°C to 60°C
  • Width: 20 mm
  • Height: 3.2 mm
  • Weight: 3 grams

What Characteristics Do CR2032 And CR2025 Have In Common?

Both CR2032 and CR2025 are 3V lithium button or coin batteries with a diameter of 20mm. They all share the same chemistry, voltage, and diameter regarding technology.

Additionally, both button batteries can run a wide variety of small devices, including computers, fitness appliances, computer motherboards, POS systems, laser pens, sensors, security devices, keyless Smart entry devices for sports cars, wristwatches, and other medical devices like clinical thermometers, heart pacemakers, blood glucose meters, and tensiometers.

If kept under similar storage circumstances, CR2025 and CR2032-sized batteries from the same manufacturer will usually have the same shelf life.

As they are two of the most commonly used batteries globally, most giant battery brands, including Maxell, Duracell, Panasonic, Energizer, Philips, Murata (Sony), Renata, and others, integrate both CR2025 and CR2032 and CR2025 in their product portfolio.

Are The CR32 And CR2025 Batteries Interchangeable?

The CR2032 can be used instead of the CR2025 and vice versa as long as they fit in each other’s compartment, even though the CR2032 will probably last a bit longer because it has a larger capacity (mAh).

Tips: You can take a piece of aluminum foil and fold it up or another lead to fit the extra 0.7mm clearance if you find the use of CR2025 difficult. Close the battery compartment after placing it on top of the battery’s positive connector to keep it stay put. If you do not make sufficient contact between the battery and spring, your battery may continue to die or work intermittently.

This is not ideal as CR2025 batteries cannot last long in CR2032-compatible equipment. However, using the CR2025 as a CR2032 battery replacement is still a possibility only in emergency cases.


The shape or structure of CR2025 vs CR2032 battery is the same as the buttons. The two different types of batteries also share similar characteristics, such as both batteries having a diameter of 20mm and a voltage of 3V.

Despite the CR2025 and CR2032 battery equivalents, they still differ on several points. It includes weight, thickness, durability, capacity, price, and others. In addition, each battery is also mainly used in various products.

From the above data, we can deduce that CR2032 batteries are generally superior to CR2025 batteries because they have a larger capacity and a longer lifespan.

  • Examine the battery compartment prior to inserting the batteries. You will see or., meaning positive and negative respectively marked on the base or side of the battery compartment. If the marking is on the label, it often shows a diagram of the battery indicating which way around it needs to be inserted.
  • Look at your battery; it has a flat side and a slightly rounded side. The flat side has a large marked on the top. Insert the battery into the battery compartment ensuring the side of the battery touches the terminal.
  • Close the battery cover by sliding it in place or pressing it so it clicks shut. If it is held in place using a small screw, insert the screw in the screw hole and tighten using a small screwdriver.

What Is The Difference Between A 2032 Battery And A 2025 Battery? (Facts)

The industry of coin batteries is growing insanely and experts say it will make a remarkable impact by 2027. These are commonly used in many household devices depending upon their type and size. The real question is; are both the batteries any different?

Despite belonging to the coin cell family, they both differ in terms of capacity and dimensions. Both coins have a similar diameter of 20mm. As you see, the initial numbers 2 and 0 show the diameter of the batteries. While the last two numbers indicate how thick both the coin batteries are. The thickness of the 2032 battery is 3.2mm while that of 2025 battery is 2.5mm.

The 2025 battery is 0.7mm thinner. Therefore, it has less capacity and may last a little less than the other one. Their availability in local stores makes it easier to use them in common household devices.

If you want to replace 2025 with 2032, it may fit in the hole as the width of these is identical. However, 2032 will be a tight fit in the holder as it is thicker to fit in the holder designed for a thinner battery like 2025.

If you’ve any concerns about how long these batteries would last and what their uses are, you should stick around. As I’m going to share an in-depth knowledge.

Coin Battery

As a result of their long lifespan, coin batteries are used extensively in small devices such as toys and keys. Another common name for coin batteries is lithium. These batteries may not come with warnings or proper indications, but it’s really important to know their downsides.

Though the size of these batteries is really small, you should be more careful when you’re with kids or pets. Swallowing and choking on these can cause serious harm to health.

Are Coin Cells Rechargeable?

No, they are non-rechargeable. But due to the non-rechargeability of coin cells, they have a life expectancy of almost a decade. I would like to add that coin batteries are different from button batteries. The former type is lithium, while the latter type is non-lithium.

As you know that lithium batteries, such as Cr2032 and Cr2025, cannot be recharged. That’s the case with most lithium-based cells. Whereas all non-lithium cells are chargeable.

Coin Cells vs. Button Cells

The first distinction is their size. The size of the coin cell is exactly a coin. Button cells are of a shirt button size. Another main difference between both is that coin batteries are only useful till they have the power or charge that devices need to run. While button or secondary batteries are rechargeable or in other words they have multiple lives. If we talk about the capacity of both, it ranges between 1.5 to 3 volts.

Here’s how coin cells differ from button cells;

How would you know if these cells are good or bad?

Any coin cell with a voltage of 3 can be considered good. These types of cells with voltage less than 2.5 are bad. When it comes to button cells, ideally, a button cell should have a voltage of 1.5. A button battery with a 1.25 voltage or less is a bad cell.

The 2032 vs. 2025 Battery Specs

Here are the specs of the CR2032 battery:

You can substitute the CR2025 for the CR2032. A thin strip of aluminum foil can be used to fill the 0.7mm gap. However, it may not be possible to use CR2032 in holes designed for CR2025.

If you intend to use two 2025 batteries, firstly they may not fit. Somehow, if they do, you’ll be feeding your device 6V. Therefore, the device may suffer a consequence. The circuit could either burn itself down or could completely shut down.

The CR2032 has a thickness of 0.7mm greater than the CR2025 when comparing their dimensions. Thus, the diameter (20mm) of these is similar. The height difference between both makes it impossible to interchange them. The cell 2032 has more capacity as compared to the 2025 battery.

The CR2032 comes with a 220 mAh capacity, while 2025 has a capacity of 170 mAh.

Final Thoughts

Overall, both batteries come with similar specs. The performance and life span may vary. However, there might also be differences in their height, capacity, and price. As you may know, these batteries go a long way, so it’s better to buy the right one from a reliable source to avoid day to day hassle.

There are two possible reasons why batteries might not work. First of all, you should always remove the stickers. Sometimes, flipping the side also works. Ensure that pets and children are far away from them.
