Coin batteries are tiny energy sources that power mobile devices, computers, remotes, toys, key fobs, calculators, electronic thermometers, flashlights, watches, and more. These batteries come in a wide range of different sizes and voltages. But while there are many different types of coin batteries, it’s important to note that even if two different batteries have the same voltage, only the type of battery specified by the device will work properly. In addition, some coin batteries also have safety features, such as a bitter-tasting coating, to discourage kids and pets from swallowing them. Keep reading to learn how to choose the best coin batteries for your devices.
How we picked the best coin batteries
Coin batteries are known by this name because of their shape and because people often had to put a coin into a slot to twist open the compartments to change the batteries. Key factors that helped to select the top products included the battery type, battery shelf life, safety features, and the overall value of the product.
While coin batteries can be used in many different electronic devices, not every device uses the same type of coin battery, and the different types are not interchangeable. With this in mind, the top products are each a different type of coin battery. In addition, we considered the value and battery shelf life together because while it may seem like a great bargain to invest in a 30-pack, you may risk not being able to use all of them before the end of their useful life.
Finally, safety features aren’t something most people consider when purchasing batteries, but some coin batteries can cause death within two hours of being swallowed, so products that attempted to prevent accidental ingestion were considered superior to similar products.
The best coin batteries: Reviews Recommendations
Our extensive research into more than 40 different coin batteries is backed by years of firsthand experience dealing with a wide variety of different devices that required specific types of batteries to operate.
Best overall: Panasonic CR2016
Why it made the cut: These CR2016 coin batteries are excellent for key fobs, alarm sensors, clocks, watches, and many other electronic devices.
- Child-resistant packaging
- Shelf life of up to eight years
- Advanced sealing technology reduces the chance of chemical leaks
- Temperature resistant from 14 to 140 degrees F
Ensure that your wall clock and alarm clock tell the correct time by replacing dead batteries with a Panasonic CR2016 coin battery. This pack includes four lithium coin batteries that have a nominal voltage of 3 volts and can last for up to eight years. Just keep in mind that this is the batteries’ shelf life, so a battery installed in a device will likely need to be replaced within that eight-year window.
These coin batteries should be used only in devices that require CR2016 batteries to ensure that the device receives the appropriate amount of power without any ill-fitting connections that may cause internal damage to the battery compartment. The batteries come in a child-resistant package that must be opened carefully with scissors. This attempts to prevent the batteries from being swallowed by kids and pets. Additionally, the batteries are resistant to extreme cold and hot temperatures, ranging from 14 to 140 degrees Fahrenheit, though exposure to these temperatures will still degrade the batteries’ life.
Best for cameras: Duracell 2032
Why it made the cut: Designed for various electronic devices, such as cameras and medical devices, these CR2032 batteries are one of the most frequently used coin batteries.
- Bitter coating to deter ingestion by children and pets
- 10-year shelf life
- Child-resistant packaging
- Popular battery type suitable for many devices
One of the main benefits of using a coin battery instead of a standard cylinder battery is that coin batteries are lightweight, making them ideal for portable devices such as flashlights and watches. Used in cameras, computer motherboards, key fobs, watches, garage-door openers, toys, doorbells, medical devices, fitness trackers, and more, these CR0232 batteries are one of the most popular types of coin battery available, and this small package of four will likely be put to good use quickly.
The Duracell CR2032 3 Volt coin batteries are an excellent option for homes with kids and mischievous pets because not only do they come in a child-resistant package, but they also have a bitter-tasting coating to deter kids and their furry friends from putting them in their mouths. Each 3-volt battery can last for up to 10 years; however, it should be mentioned that some users found that they received an old, dated package with batteries that were already dead. This situation should be able to be resolved by the company with a replacement package, but always make sure to check the date of manufacture to ensure that the products are indeed new.
Best for remote controls: Energizer 2450
Why it made the cut: Store these lithium batteries for up to 10 years or use them immediately in various electronic devices for reliable, long-lasting power.
In contrast to the short shelf life and battery life of alkaline coin batteries, these Energizer 2450 3 Volt lithium coin batteries can last for up to 10 years before the stored energy is fully discharged, which should be more than enough time to put these two batteries to good use instead of worrying about throwing them out unused. Additionally, each battery is individually sealed and cannot be accessed without scissors. While the packaging may frustrate some adults, it was intentionally made difficult to open to protect kids and pets from accidentally swallowing the batteries.
Things to consider before buying coin batteries
Before grabbing the first coin batteries that look like they might work, take some time to learn about the various factors that are important to think about before your purchase, such as the battery type, the battery life, and any safety features that can help prevent accidental ingestion.
Coin battery types
It’s necessary to differentiate between the various coin batteries because even if two coin battery types have equal voltages, the different types are not interchangeable. With this in mind, it’s necessary to check each electronic device to determine the specific type of coin battery the device needs to operate.
Some of the most common types of coin batteries include CR2032, CR2016, CR450, LR44, and LR1130, but there are many more. They also typically come in alkaline or lithium options and may differ in voltage, though 1.5V and 3V are standard voltages for coin batteries.
Battery life
The life of a coin battery is difficult to determine because the rate at which the stored energy is absorbed and used depends on the amount of energy used by the particular device, the frequency with which the device is used, and the number of batteries in the device. For this reason, manufacturers do not often provide this detail; instead, they advertise the shelf life of the battery, which refers to the amount of time the battery can remain effective while not being used.
Alkaline batteries are an affordable option for low-power devices like watches, and they can last up to three years, but they have a short shelf life compared to lithium batteries, which can last up to 10 years in some cases. If you are looking for a battery value pack, remember that even when batteries are not in use, they can still lose the stored energy and become useless.
Safety features
Coin batteries certainly don’t seem as dangerous as poison or power tools. Still, if these little batteries are accidentally eaten they can cause serious harm to the body’s interior. They may even lead to death if the powerful chemicals inside the batteries leak out. Due to this inherent danger, many coin battery manufacturers have improved the battery packaging in an attempt to prevent kids and pets from opening the packages and swallowing the batteries.
Additionally, some companies have added a bitter flavoring to the exterior of each battery so that if a child or pet puts the battery in their mouth, the bitter taste will make them want to spit the battery out and avoid ingesting batteries in the future.
Some General Info on Coin Cell Batteries
Coin cell batteries are the “larger” varieties of the button cell batteries. They are still small, usually no bigger than 25mm in diameter. Compared to their smallest button cell battery cousins, at 5mm, they are quite larger.
As you can see in the photo above, the size, voltage and country of its manufacturer are stamped right on the coin cell battery itself.
Coin cell batteries are single cell, typically disposable (but not always, as we’ll see), and measured in millimeters due to their small size. Their charge capacity is given in milliampere hours (mAh).
Coin cells have a long service life, from one to 10 years, depending on the type. They have a low self-discharge rate, and hold charge for long periods of time when not in use.
32 Coin Cell Batteries
Since we’re talking about three types of 2032 batteries today, let’s look at them specifically for a moment.
Each coin cell battery is labeled first by its diameter. Therefore, 2032 batteries are 20mm in diameter. The 32 comes from their thickness, which is 3.2mm.
No other coin cell battery has these dimensions. When you see 2032 on the label, you know it is this size.
2032 batteries all carry at least a 3V charge. They have a shelf life of at least 10 years. And at least some 2032s are rechargeable, depending on the chemical materials used to create their cathode cell.
Here’s a photo of our Duracell Procell CR2032, with the designation and voltage clearly visible on the product packaging.
Coin Cell Battery Chemistry
A battery’s chemistry can have great effects on its performance. Here are other things that can be affected by what a battery is made of:
- Performance at various temperatures
- Rechargeability vs. disposable
- Gravimetric energy density.- how much energy a battery holds vs. its weight
- Service life. while in use
- Shelf life. when not in use
The three coin cell batteries we’ll be examining each have their own chemical make-ups for their positive cathodes. Let’s look at them now.
CR2032 Battery Chemistry
The “CR” in a CR2032 battery, or any CR designated battery designates that its positive cathode is made of Lithium manganese dioxide. This gives it a high energy density while also allowing it to function in low-temperature environments.
The LiR2032 is a rechargeable lithium battery whose performance greatly depends on the type of lithium used by the manufacturer. They also carry a higher voltage charge, from 3.2 to 3.9V. Common types of lithium used in LiR coin cell batteries include:
- Lithium manganese oxide
- Lithium nickel cobalt aluminum oxide
- Lithium cobalt oxide
- Lithium iron phosphate
What are CR2032 Batteries?
The CR2032 battery is a non-rechargeable (primary) battery that is very common today. It is a coin-cell battery which utilizes lithium chemistry. These batteries are used in a wide range of applications and are available from many retailers. Most major battery brands like Duracell. Energizer. Panasonic. Philips, Maxell. Murata (formerly Sony), Renata. and others offer model(s) of the CR2032 battery; both as a bare cell and with different attachment options.
CR2032 Battery Nominal Voltage:
Operating Temperature:
Width (Diameter):
MicroBattery Pro-Tip (Understanding Lithium Coin Batteries): Lithium coin cell batteries are usually designated with a CR followed by a set of numbers. The C in CR lets you know the battery uses a lithium chemistry. The R lets you know that the battery is round in shape. The first two numbers let you know the diameter of the battery and the last two numbers tell you the height. So by following this, you can easily see that a CR2032 battery is a (C) lithium chemistry battery with a (R) round shape that has a diameter of (20) 20 millimeters and a height of (32) 3.2 millimeters. This applies to the majority of coin and button cell batteries but note there are some exceptions, like the CR2 or CR123A batteries which are considered lithium cylindrical batteries.
What Battery Is Equivalent To The CR2032 Battery?
The CR2032 battery is also known as the 5004LC, BR2032, CR2032, DL2032, ECR2032, KCR2032, and KECR2032 depending on the manufacturer. Other lithium coin cell batteries may have a similar voltage, diameter, or height as the CR2032 battery, but may not work in devices that require a CR2032. For example, a CR2016 has the same diameter and voltage as the CR2032, but has half the height and may not fit securely into the device you are trying to power. A CR1632 battery would have the same height and voltage of the CR2032 but would have a diameter that is 4mm too short to securely fit in the same device. It is important to understand the specifications of your device’s battery in order to get the best use out of the battery.
Battery storage life can depend on a variety of factors including material quality, storage conditions, storage time, humidity, physical damage, or temperature. Ideally you would want a battery made of high quality materials, stored in a climate controlled and dry area, with no physical damage. Energizer claims that their lithium coin cell batteries have up to 10 years of shelf life when properly stored. As far as service life this will depend greatly on the application. A CR2032 battery in a car key fob may last up to 4-5 years before needing replacement as the use of the battery is very intermittent. A more active device such as the new Apple Air Tag which allows constant tracking of objects will only last about a year.
What Uses a CR2032 Battery?
The CR2032 battery is used in a wide variety of devices and applications including computer motherboards, car key fobs, watches, calculators, PDAs, electronic organizers, garage door openers, toys, games, door chimes, pet collars, LED lights, sporting goods, pedometers, calorie counters, stopwatches and medical devices.
CR2032 batteries are extremely common and popular. This means that a wide variety of manufacturers make these batteries and a wide variety of retailers sell the battery. It is important to keep in mind that not all CR2032 batteries are created equal and that not all retailers have the same dedication to quality. To avoid low quality or worse, counterfeit batteries, it is important to only purchase your batteries from a highly reputable retailer that sells only the highest quality of brands.

Rechargeable? Only the types ML and LIR!
Since I was asked if the CR2032 and CR2025/2016 are rechargeable, I did a little research in this direction. The result: The variant with “CR” at the front is always a disposable battery. Only the models with “ML” and “LIR” in front (i.e. ML2032 or LIR2032) are rechargeable batteries. If you try to charge the CR button cells, they can explode in the worst case. Due to the built-in lithium, this is usually associated with flames, which can lead to a fire on flammable surfaces. So before loading, please check the designation of the button cell!
A question that a reader asked me should still be answered: What is the difference between ML2032 and LIR2032 and what do these abbreviations stand for.
The difference between these two types of button cell is not only in the chemical composition, but also in the nominal voltage and the charge:
Now which is the better choice? ML or LIR? In most cases, this is probably the ML button cell, as it has a higher energy density than the LIR variant and thus “lasts” longer. However, both types cannot match the runtime of a disposable CR button cell, which can deliver almost three times as much energy as an ML button cell.
2x CR2016 = CR2032? NO!
I was recently asked whether you could use 2032x a CR2 button cell instead of a CR2016. The dimensions are then identical and it would fit into the corresponding device, but you would have connected two 3,0 volt batteries in series, resulting in a total voltage of 6,0 volts. This is twice as high as the voltage that the device actually expects and one can assume that the calculator or the remote control. or whatever device it is. will be permanently damaged. In short: the probability is very high that you will break the device with it. So: 2x CR2016 ≠ CR2032.
Today I got a trick from my reader Helmut on how you can help yourself when a CR2032 is necessary, but you only have a CR2016 or a CR2025 available. It’s the same if you need a CR2025 but only have a CR2016 on hand.
The only problem here is the lack of height, which prevents the flatter model from being used. In terms of tension, there would be no problem.
To compensate for the missing height, you can make a small ball out of aluminum foil and insert this into the device with the flatter button cell. It is important, however, that the ball does not slip towards the edge, otherwise there is a risk of a short circuit. And you should always only press the aluminum ball on the top of the button cell, since no contact with the other pole is possible on the top.
The trick is ok if you know what you are doing. I would say: “Use at your own risk!”. A short circuit in a button cell can quickly lead to an explosion of the battery, which should be avoided at all costs. But maybe the trick will help one or the other reader out of an emergency. Thanks for the addition, Helmut!
Where can I buy the button cells?
While button cells of the same type all look the same at first glance, there are different offers in terms of quality. In practice, you quickly find that non-name offers often look like new batteries, but have usually been stored for too long and are therefore no longer completely full. Within a short time the devices are empty again and you have to buy appropriate button cells again.
If you prefer to FOCUS on quality here, you should choose brands such as Duracell or Varta. These usually have a shelf life of up to 10 years and are not empty again shortly after the battery has been changed. I have listed the corresponding offers here:
Lr44 Battery Equivalent Duracell
Are you looking for an LR44 battery equivalent? If so, you may be wondering what your options are. The LR44 is a small, button-shaped battery that is commonly used in watches, toys, and other small electronic devices.
These batteries are not rechargeable and must be replaced when they run out of power. While the LR44 is a very common battery, it can be difficult to find an exact replacement. This is because there are many different types of button batteries on the market, each with its own unique size and voltage.
However, there are some good alternatives to the LR44 that will work just as well in your device. Some of the most popular LR44 substitutes include the CR2032, CR2025, and CR2016 batteries. These batteries are all slightly different in terms of size and voltage, but they should work fine in most devices that require an LR44 battery.
And if you can’t find one of these specific models, any other 3V button battery should do the trick!
Lr44 Battery Equivalent 675
As we all know, batteries are an essential part of many electronic devices. Without them, our phones, laptops, and other gadgets wouldn’t be able to function. While there are many different types and sizes of batteries out there, one type that is commonly used in small electronics is the LR44 battery.
The LR44 battery is a small, button-shaped battery that is often used in watches, calculators, and laser pointers. If you’ve ever had to replace the batteries in any of these devices, chances are you’ve used an LR44 battery before. While the LR44 battery is a common type of battery, it can be difficult to find an exact replacement if yours dies or runs out of power.
That’s because there are actually several different types of batteries that can be used as an LR44 equivalent. Some of the most common LR44 equivalents include the CR2032, CR2025, and CR2016 batteries. These batteries are all slightly different in size and capacity, but they should work just as well as an LR44 in most devices.
If you can’t find one of these specific replacements, any similar sized button cell battery should do the trick. Just be sure to check the voltage and amperage ratings to make sure it will work with your device before making a purchase.
Conclusion
If you’re looking for an LR44 battery equivalent, there are a few options available. The CR2032 is the most common and widely available option. Other options include the BR2032 and the L1154.
All of these batteries will work as an LR44 replacement, though they may have slightly different performance characteristics.
