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.

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.


Q. What is the most common coin battery?

The most frequently used type of coin battery is the CR2032 battery. It’s a non-rechargeable lithium coin battery regularly used in calculators, watches, fitness trackers, and other small electronic devices.

Q. How long do coin batteries last?

On average, coin batteries will have a shelf life of about two to three years; however, some lithium coin batteries have longer shelf lives and have been known to last up to 10 years without needing to be replaced. It should be noted that the battery life can be diminished by extremely cold or hot temperatures, so the batteries must be stored at room temperature and sheltered from wind, rain, and snow.

Q. Are all 3V coin batteries the same?

The voltage of two or more coin batteries can be equal, but they cannot be used interchangeably. For instance, the CR2016 and CR2032 are both 3-volt batteries. Still, they have different dimensions—the CR2016 is thinner than the CR2032, so a CR2032 battery would not physically fit in a battery compartment made for a CR2016 battery.

Q. Are coin batteries dangerous?

One of the problems with coin batteries is that their small size makes them easy for children and pets to swallow. Once ingested, the child or pet may experience internal harm from electrical currents, physical pressure on sensitive tissues, and leaking chemicals from the battery. To help prevent this, some manufacturers have given the batteries a bitter flavor that discourages children and pets from putting the batteries in their mouths. However, it’s advised to keep coin batteries out of reach of small kids and pets to avoid a trip to the hospital or vet clinic.

Final thoughts on the best coin batteries

The child-resistant packaging and convenient four-pack make the Panasonic CR2016 coin batteries an excellent option for a home with kids or pets. Still, if you need LR44 batteries, the 15-pack of AmVolt LR44 coin batteries is an affordable option for watches, clocks, remotes, and even game controllers.

CR2016 Vs CR2032 Battery – What is the Difference?

When you look at the CR2016 and CR2032 batteries, they look fairly similar; however, there is a slight difference between them. What is the difference between the CR2016 vs CR2032 battery?

Both the CR2016 and the CR2032 batteries have the same diameter, which is 20 mm. They also generate the same 3 volts. The difference between them is that the CR2016 is thinner than the CR2032. The CR2016 battery is 1.6 mm thick, while the CR2032 battery is 2.0 mm thick.

While the CR2016 battery and the CR2032 battery have the same diameter and both can produce the same amount of volts, you cannot interchange them because they don’t have the same thickness. One physical reason is that the battery holder for one may not be the same holder size for the other.

Read on to learn more about the differences between the CR2016 vs CR2032, their similarities, their uses, and how long their service lives are.

CR2016 Vs CR2032

The CR2016 battery is thinner than the CR2032 battery. The CR2016 battery is 1.6 mm thick, while the CR2032 battery is 2.0 mm thick. They both have the same diameter and generate the same 3 volts.

If a battery has the prefix CR, most probably, it is a manganese dioxide lithium battery. It is a type of battery classification of the CR2016 and CR2032. They are mostly used to power consumer gadgets, such as watches, timers, key fobs, computers, and many more. The reason they are very common is that they are generally inexpensive and long-lasting.

These two batteries are generally called button cell batteries or coin-type batteries. But they don’t have the same identification numbers; one is CR2016, while the other is CR2032. There are also other differences between them.

The following are the differences between CR2016 and CR2032:

CR2016 Vs CR2032 Battery Cell Numbers

These two batteries have different identifying numbers. Their respective numbers have a specific meaning. The first two digits mean the battery’s diameter in millimeters, while the last two digits denote its thickness, which is also in millimeters.

CR2016 has a 20 mm diameter and a 1.6 mm thickness, while CR2032 has a 20 mm diameter and a 3.2 mm thickness. In other words, while they both have the same diameter, the CR2032 has two times the thickness of CR2016.

They Are Not Interchangeable

If CR2016 has half the thickness of CR2032, is it possible to stack up two CR2016 pieces to replace a busted CR2032? No, you can’t do that. Both batteries can generate 3 volts. That means a CR2016 can produce the same volts as the CR2032.

So if you stack up two pieces of CR2016 in place of the worn-out CR2032, the batteries will generate 6 volts instead of just 3. It will be detrimental to the device you are operating because it needs a power source that provides no more than 3 volts.

In other words, although the battery holder may be able to accommodate the two pieces of CR2016, the generated voltage may damage the electronic circuit of the device you are running.

They Don’t Have the Same Capacity

A battery’s capacity is measured in milliampere-hour or mAh. It is the amount of charge that the battery can store. The amount of charge is dependent on the mass or volume of the active material inside the battery cell.

An average CR2016 battery has a capacity of around 90 mAh. It means this battery will last for approximately six hours if you are using it with a 15 mA load.

In the case of the CR2032 battery, its capacity is around 240 mAh. It means this battery can last approximately 10 hours if you use it with a 24 mA load.

CR2032 Vs CR2016 Battery Thickness

The thickness of a coin-type battery is given in millimeters. And the last two digits of a battery’s identifying number represent the thickness of CR-series batteries. So, for the CR2016 battery, the thickness is 1.6 mm. And the thickness of the CR2032 battery is 3.2 mm, double that of the CR2016.

These two batteries are only similar in three aspects. They are the same in diameter (with both having 20 mm diameters), both of them can generate 3 volts, and both are disposable, meaning you can’t recharge them. These two battery types contain lithium ions, which could spill if you attempt to recharge them.

What Is a CR2016 Battery?

You could have been using the CR2016 battery for a long time without you being aware of it. It is most commonly used to power most modern small and portable electronic gadgets. The shelf life of this battery could last as long as 8 to 10 years.

cr2016, cr2032, battery, difference, 2032

This battery can provide continuous voltage to electronic devices, providing safe and reliable operation. It’s also temperature-resistant and can withstand even the most harmful changes in temperature.

Uses of CR2016 Battery

Another term for CR2016 battery is ‘button cell’ that can run small portable electric gadgets, such as calculators and small watches. You can also call these batteries ‘coin cells’ because they are similar to small coins.

Electronic devices that use these coin-type batteries have designs that provide long service lives. Usually, CR2016s can last more than a year of continuous use, such as in wristwatches.

These batteries also have low self-discharge rates; therefore, you can expect them to last many years when not in use. But when you use them in electronic devices that require higher capacities, they will run out of juices in a short time.

The most common uses of CR2016 batteries are for powering digital watches, fitness appliances, electronic timers, calculators, car key remotes, kid’s toys, special medical devices, and many more. You often use this type of battery in pairs instead of just one, like in LED flashlights.

How Long Do CR2016 Batteries Last?

CR2016 batteries typically have shelf lives of six years. But one battery manufacturer claims that its single-use silver-zinc battery has a 10-year shelf life. If you read watch manuals, especially those from G-Shock watches, they say that a CR2016 can power the device for two years.

Some believe that they are just a conservative estimate. If you don’t use the auto EL light function, the hourly chime, or the alarm in your watch, the battery could last about seven years or more. This is based on real-life experiences of consumers using their electronic watches powered by CR2016 batteries.

In our comparison of the cr2032 vs cr2016, we’ve looked at the CR2016 battery; next, let’s look at the CR2032 battery.

What Is a CR2032 Battery?

The CR2032 battery is also a coin-type lithium-ion battery that can produce 3 volts. It is popularly known as the CMOS (complementary metal-oxide-semiconductor) battery. You can also use these batteries for powering a computer’s BIOS or the real-time clock of computers.

The identification number CR2032 is an International Electrochemical label. It is called 5004LC by the National Electronics Distributors Association (NEDA) and the American National Standards Institute (ANSI).

In specific terms, the CR2032 is a battery made of lithium-manganese dioxide (LiMnO2). Its anode is made of lithium, and its cathode is made of manganese dioxide. The temperature range that this battery can operate is from.20°C to 70°C (-4°F to 158°F).

This battery has a low self-discharge rate, so you can store it for years and retain most of its original charge.

Uses of CR2032 Batteries

The CR2032 battery is typically used in providing power to electronic subsystems that require ultra-low power, like oscillators and real-time clocks. Their design offers low power even if the system power that runs the device is turned off.

As such, their common use is to power the real-time clocks of computer motherboards. They also function as a real-time clock (RTC) and non-volatile BIOS memory backup batteries. The design of modern electronic devices is to prevent drawing power from the CR2032.

How Long Does a CR2032 Battery Last?

Normally, if you use it in computers and other electronic devices, it could last up to two years before it dies. You can calculate the battery life of a CR2032 by dividing its total charge in mAh with its current consumption.

If the device is drawing 1 microamp or less continuously, a CR2032 can last for ten years. This can be possible in situations where the CR2032 is just powering the computer BIOS. However, in most situations, the battery is called to supply more current in pulses or even in a continuous manner.

During normal operations of electronic devices, subsystems such as the RTCs are powered by the device’s main power supply instead of the CR2032 (as long as the device is running). So, more often than not, the device is already worn out, while the CR2032 inside it is still good and operational.

We’ve discussed the difference between the CR2016 vs CR2032 battery; now, let’s take a look at a brief history of coin-type batteries.

History of Coin-Type Batteries Including the CR2016 and CR2032

The very first battery cell was invented by Alessandro Volta, as far back as 1799. But while Volta’s fundamental concepts were followed in subsequent battery developments, his first battery design underwent a lot of changes, improvements, and innovations, up to our modern times when battery coins were developed.

Button cells were developed in tandem with the first electric watch movement. Arthur Fillinger developed the Model 500, the first electronic watch, in 1951. He asked 40 battery makers to produce a small battery to power his watch, but they all turned him down.

However, there was one battery maker that agreed to do it – Union Carbide. Thus, the 301 (SR43SW) battery was born. It was later replaced by the 387S. These were mercury button cells that produced 1.35 volts. Their cells are composed of mercuric oxide with leads made of zinc.

However, the use of mercury was discontinued because it was considered then, even now, as an environmental hazard. They replaced it with silver oxide. The batteries made with this material generated 1.55 volts. This battery became the industry standard and is used in coin batteries to this day, including the cr2016 and 2032 batteries.

Two requirements influenced the development of button batteries back then. One is that they should be low profile, and the other is that they should provide long service lives. The overall requirement is that they should be able to provide power 24/7 for one year or even longer.

These power demands can be satisfied with lithium and alkaline batteries that produce 3 volts and 25 to 210 mAh. Thus, the button batteries that power your electronic gadgets can now support your electronic activities continuously and for a long time.

Conclusion – CR2032 Vs CR2016

CR2016 vs CR2032 – how do they compare? Both the CR2016 and the CR2032 have the same diameter, which is 20 mm. Their significant difference is in their thickness. The CR2016 battery is 1.6 mm thick, while the CR2032 battery is 2.0 mm thick.

Both batteries can produce 3 volts. But since they don’t have the same thickness, you can’t interchange them. You can’t also stack up two CR2016 to replace one CR2032. If you do it, you will generate 6 volts, which would be disastrous to the gadget you are using.

What makes a good CR2032 Battery?

CR2032 batteries are referred to as a lithium coin cell. They are interchangeable with all models with the preceding 2032 name. The name is derived from the dimensions of the battery, being 20mm x 3.2mm. Lithium batteries are much more suited for high drain devices as opposed to their alkaline couterparts.

Capacity – The standard capacity of a CR2032 battery is 225mAh but this could be higher or lower depending on the manufacturer and also the age of the battery. The milliampere-hour may also vary slightly from battery to battery. For instance energizer panasonic CR2032 has a stated capacity of 225mAh whereas an energizer has 235mAh. This determines the amount of energy the battery has.

Voltage – CR2032 batteries are rated at a standard 3V (three volt). Testing the batteries may produce differing results. This is due to age and also manufacturing process. Testing a fresh CR2032 should yield a result of 3V but slightly higher or lower is normal.

Operating Temperature Range – All brands of CR2032 battery are very tolerant to extreme temperatures out of the normal operating range. The standard range is.20 degrees C – 60 degrees C. Some brands have a wider operating temperature but depending on your application or device you may want to check the datasheet of the specific manufacturer to determine the best suited battery for your needs.

Long Shelf Life – Lithium coin cell batteries are well known for their long shelf life. Often exceeding 10 years are 80% capacity. Batteries are best stored in a dry cool place in the recommended operating range. Keep batteries away from damp and wet areas including very humid basements and attics. The extreme temperature change will eventually degrade the batteries longevity.

No Leak Design – CR2032 batteries are encased in a stainless steel enclosure and pose very little risk of leaking. Only batteries stored in sub optimal conditions will degrade enough that they may leak. If a battery has been left in a damp or wet place and you are concerned then dispose of it appropriately.

Q: Is a CR2032 battery rechargeable?

A: A CR2032 battery non rechargeable coin shaped battery. The rechargeable equivalent of a CR2032 battery is called the BR2032 battery. These are a very uncommon battery. Definitely do not try to charge a standard CR2032 as this could cause a fire.

Q: What is the difference between a CR2032 and CR2016 battery?

A: CR2032 battery dimensions are 20mm x 3.2mm whereas the CR2016 battery is half the height registering at 20mm x 1.6mm. This essentially means that two CR2016 batteries can be used to replace a single CR2032 battery. This is not recommended but for a short term solution this will work fine. Capacity of CR2016 is much smaller than CR2032 so don’t use this a long term solution.

Q: What is the difference between a CR2032 and CR2025 battery?

A: As noted above the only difference between these batteries are the physical dimensions and the capacity. CR2025 has dimensions of 20mm x 2.5mm. These cannot be used to replace a CR2032 without some insert to negate the empty space.

Q: Are CR2032 and CR2025 batteries interchangeable?

A: Not exactly. See the above answer.

Q: How do you dispose of CR2032 batteries properly?

A: Because oCR2032 batteries contain dangerous chemicals it is essential to dispose of them properly. Most states and countries have specific rules governing the disposal of lithium batteries. Definitely do not dispose of them with your regular trash. Even if the contacts are separated they could pose a fire risk. Google your statecounty to check for local ordinances regarding lithium battery disposal. Most localities have a designated battery recycling drop off location.

Q: How long do CR2032 batteries last?

A: As discussed earlier CR2032 batteries have a shelf life of between 5-10 years if stored correctly. The power your device uses will determine how long the CR2032 will last.

Q: Which is the best quality CR2032 battery?

A: This is not an easy answer. Depending on your use the answer will vary. Sony, energizer, Maxell and Panasonic are all big brand names but this does not mean the little guys are producing lesser quality batteries. Check datasheets and manufacturer websites.

Q: Is a DL2032 and CR2032 the same?

CR2032 vs BR2032 vs LIR2032 Coin Cell Batteries | Side-by-Side Comparison

The BR2032 is very similar to the CR2032m, except it uses carbon monofluoride as the positive electrode, instead of manganese dioxide, which is found in the CR2032.

The IEC standard 60086 defines the 2032 battery as a round cell with 19.9 (±0.1 mm) in diameter and 3.1 (±0.1 mm) in height – 2032 actually means 20 mm in diameter and 3.2 mm in height.

Depending on the model and manufacturer, 2032 batteries weigh around between 3.0 g and 3.2 g.

CR2032 Batteries Specifications and Comparisons

The CR2032 battery can be replaced with a BR2032 battery without the danger of damaged electronics and in most cases, devices will work properly.

What Else Should You Know about Replacing CR2032 Batteries?

However, the CR2032 and BR2032 SHOULD NOT be replaced with a LIR2032 battery due to voltage differences – 0.6V doesn’t sound much, but it is enough to damage your electronics. We also advise not to replace single-use batteries with rechargeable ones, for safety reasons.

Before replacing a CR2032 or BR2032 battery with a LIR2032 check the device manual or contact the device manufacturer directly.

The DL2032 battery is a CR2032 battery produced by Duracell, while the ECR2032 battery is a CR2032 battery produced by Energizer etc. Also note that manufacturers use both CR2032 and custom designations.

In high-end and/or robotic vacuum cleaners, if CR2032 batteries are present, they are used as motherboard batteries as they can hold the charge for many years and keep the CMOS memory functioning properly.

Not sure what batteries you need for your cordless vacuum cleaner?

Use our guide to learn all you need to know about vacuum cleaners’ battery types so you can make the best choice for your needs!

LIR2032 batteries, on the other hand, have very high self-discharge rates when compared with the CR2032 and BR2032 batteries and there is really no need to use them in vacuums as CMOS support or for similar functions.

If you do require new CR2032 batteries, for a vacuum cleaner or some other device, consider buying batteries from reputable sellers and manufacturers. Generic batteries may be cheap but saving a few dollars now may cause numerous headaches later.

BR2032 or LIR2032 Batteries vs. CR2032

We haven’t mentioned any BR2032 or LIR2032 in our chart. BR2032 batteries’ wider temperature range is not so important for vacuum cleaners (that have inner home temperatures of below 20°C) and LIR2032s have an unacceptable self-discharge rate when compared with CR2032s to be used in vacuum cleaners, laptops, calculators, and similar devices.

A LIR2032’s price vs. a CR2032’s price: A quality CR2032 battery is as expensive as a quality LIR2032 battery – or it costs even more!

However, if you are looking for good LIR2032 batteries with charger, Zackees Rechargeable USB Coin Cell Charger with 2 provided batteries or CT-ENERGY Lithium-Ion 2032 Battery Charger with four LIR2032 batteries.

Both are nice sets that come at a reasonable price.

cr2016, cr2032, battery, difference, 2032

The capacity of these batteries is on average around 35-40 mAh (CR2032 200-225 mAh), but they can handle a discharge rate of about 70 mA, while the CR2032’s max burst discharge rate is around 15-16 mAh.

Again – LIR2032 batteries have 3.6V, while CR2032 3V. Unless you are absolutely sure that your device can handle this increase in voltage, DON’T use LIR2032 batteries instead of CR2032 batteries

Such (small) increase in voltage may damage or make a device act strangely, to say the least.

CR2032 vs BR2032 vs LIR2032 Coin Cell Batteries: FAQs

Are all 2032 batteries the same?

All 2032 batteries are 20mm in diameter and 3.2mm thick. However, there are two main models on the market today: the CR2032 batteries and the BR2032 ones. The main difference between these two types resides in their electrode. While similar, the BR2032 uses carbon monofluoride as the positive electrode. The CR2032 uses manganese dioxide for the positive electrode.

What is the best brand of CR2032 batteries?

We recommend the Duracell and the Energizer CR2032 batteries. Both companies are fierce market competitors when it comes to the production of powerful and reliable batteries. However, all of the options we presented above are great, so you can take your pick!

What devices require the use of a CR2032 battery?

Usually, you will find CR2032 batteries in appliances such as car keys, laser pens, fitness appliances, medical appliances (tensiometers, clinical thermometers, etc.), digital watches, memory backup, etc. Some toys also run on this type of battery because of their resilience. Since they don’t need constant replacing, they can be secured behind screws with minimal inconvenience, making them a safe choice for children’s toys.

How can I properly dispose of CR2032 batteries?

The sensible thing to do to correctly dispose of CR2032 and all other batteries is to take them to a specialized center, appliance store, or any other point that collects used batteries. Look online for the used battery disposal and collection advice regulations in your city or community. If you don’t have any other alternative but to throw them in the trash, make sure you don’t dispose of a large number of CR2032 batteries at once. Avoid placing other metals near the batteries in the trash, and make sure the batteries don’t touch each other while in the trash.

How do you know if a 2032 battery is good?

First and foremost, you’ll need a multimeter to determine whether a 2032 battery is still good or not. Turn the multimeter on and set it to “DC Voltage” mode. The red part of the probe should touch the positive part of the battery, whilst the black probe needs to touch the opposite end, the negative one (-).

As you already know by now from the article, the CR2032 is a 3-volt battery, so the measured voltage should read more than 10% of the rated voltage. specifically, for the CR2032 that means 2.7 volts or more if the battery is good. If it’s gone bad, then it will read less than that value.

How many years does a lithium battery last?

The typical estimated life of a lithium battery is around 3 to 5 years, but CR2032 batteries can last up to 10 years of use. So, we’ve covered that particular question for this type of battery. For now, let’s FOCUS on standard lithium batteries since how they work is a little more complicated. A typical lithium battery can last anywhere between 300 and 500 charge cycles. One charge cycle is the period between a full charge, complete depletion, and then a full recharge. In that sense, most lithium batteries will only last a maximum of five years. As for batteries that don’t get fully charged and depleted, they also lose their capacity over the same amount of time due to wear and tear.

How do I dispose of a CR2032 battery?

Thankfully, CR2032 batteries don’t contain any toxic metals or reactive acids. By the time your CR2032 battery loses its charge, the highly reactive lithium inside of it has been transformed into a non-reactive metal compound. Used CR2032 batteries don’t generate that much heat on their own, and they pose no risk of releasing chemicals that could make it into your local ecosystem. Still, throwing them in the trash is risky, so just recycle them at the local waste plant.

Bottom Line

Here is everything you need to know about CR2032 batteries, their use, and even advice for proper disposal! If you have more questions, feel free to pop them in the Комментарии и мнения владельцев section below and we will get back to you!
