What does CR2032 Stand for?

CR2032 battery falls under the category of primary batteries. Although they are non-rechargeable, their rechargeable version is also available- LIR2012.

cr2032, batteries, rechargeable, know

It uses lithium as the anode and compounds from the air such as cupric oxide, manganese oxide, oxygen, etc as the cathode. It is easy to recognize the terminals of the CR2032 battery. The rough texture end is the negative terminal and the opposite flat surface is the positive terminal which is indicated on the battery as ‘’.

While most of the batteries produce a nominal voltage of 1.5V, the nominal voltage of CR2032 is 3V. As these are small in size and produce high power, the weight-to-power ratio of CR2032 is very high. The self-discharge tendency is also very low.

Power stability is another celebrated characteristic. This is due to its low internal resistance. This enables its high conductive electrolyte to provide stable power at normal room temperatures as well as at high-low temperatures.

As these batteries are carried in sealed cases, they are leak-poof to a large extent. Since no toxic elements like mercury or cadmium are added, they do not harm the environment. But the cost and damage due to overcharging are considered significant limitations.

CR2032 Battery Equivalent/alternative/replacement

The CR2032 battery can be replaced with 5004LC, BR2032, CR2032H, L2032, AWI L14, DL2032, ECR2032, EA2032C, BR2332, KCR2032, KECR2032, LF1/2V, LM2032, RFA-35, and SB-T15.

Some other equivalent CR2032 batteries are CR2025, CR2016, CR1632, CR1620, CR1616, CR1220, and CR1216. But keep in mind that you will have to make some mechanical adjustments in order to use one of these in place of CR2032.

What is a CR2032 Battery used for?

Since CR2032 batteries are very compact and small in size, they are very suitable for tiny devices. With the larger nominal voltage and high power capacity, they are efficiently utilized for a large number of commercial as well as medical purposes. Some of the important applications of CR2032 batteries include:

  • Motherboards to security system panels
  • Car key fobs
  • Watches
  • Calculators
  • PDAs
  • Electronic organizers
  • Garage door openers
  • Toys
  • Door chimes
  • Pet collars

  • Stopwatches
  • Pedometers
  • Calorie counters
  • Hearing aid
  • Glucose monitors
  • Tensiometers
  • Clinical thermometer

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.

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.

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.

CR2032 Specifics

Now that you have a general feel for coin batteries as a whole, let’s look more specifically at the technical details of the CR2032 battery.

Terminal Features

Coin batteries come with different terminal features, and the CR2032 is no exception. CR2032 batteries have a flat top, button top, or pressure contact terminal.

A flat top terminal is just a small, flat spot on the top of the battery. A button top terminal is slightly elevated above the surface of the battery, and it has a small, raised button in the center. Pressure contact terminals are also slightly elevated, but they do not have a button – instead, they have two raised bumps on either side of the terminal.


All coin batteries have a voltage of 1.5 volts or 3 volts. Lithium coin batteries such as the CR2032 battery are a 3-volt battery, which means that it has a higher voltage than other coin batteries, such as the LR41 alkaline battery, which is only 1.5 volts. This higher voltage allows the CR2032 battery to power devices that require more power, such as medical devices and toys.


Coin batteries come in a variety of sizes, but they are all small and round. In terms of size, the diameter of the battery is 20 mm and the thickness (height) is 3.2 mm. This makes it a bit thicker than some other coin batteries, such as the CR2025, which is only 2.5 mm thick.


The capacity of a coin battery is measured in milliamp hours, or mAh. This measures how much charge the battery can hold. The CR2032 battery has a capacity of 235 to 240 mAh, which means that it can power a device for a long time before it needs to be replaced.

Operating Temperature

The operating temperature of a coin battery is the temperature range in which the battery can be used. The CR2032 battery has a wide operating temperature range of 0°C to 60°C. This means that it can be used in a variety of devices, in cold and mildly warm temperatures.

How Long Does A CR2032 Battery Last?

The lifespan of a coin battery varies depending on the type of battery and how it is used. For example, alkaline batteries have a shorter typical lifespan than lithium batteries. The CR2032 battery has a long shelf life of 3 to 5 years.

This means that, if you use your device regularly, you can expect to replace the CR2032 battery every 3 to 5 years. However, if you only use your device occasionally, the battery may last longer.

The Benefits and Challenges of the CR2032 Battery

  • Third, since it is a small battery, the packaging won’t take up much storage space in your junk drawer or wherever you store them. Finally, if you need to replace the battery, it is easy to find replacements online or at your local store.


When using coin batteries, there are a few things to keep in mind.

  • First, because they are small and round, they can be difficult to handle. It is important to be careful when inserting and removing them from your device.
  • Second, since they are small, they are easy for children to swallow, and they are extremely dangerous and life-threatening if ingested, so please keep them out of the reach of children.

How to Replace a CR2032 Battery

Coin batteries are easy to replace, and the CR2032 battery is no exception. The simplest way to replace the battery is to remove the old battery and insert the new one in its place.

  • Hold it with your thumb and first finger. Gently pull on the tab until the battery comes out. If the tab breaks, you can use a small pair of tweezers or needle-nose pliers to carefully remove the battery.
  • Once you have removed the old battery, compare it to the new one to make sure they are the same size and shape. If they are not, do not force the new battery into place. Find a replacement that is the same size and shape as the old one.
  • To insert the new battery, hold it with your thumb and first finger. Gently press it into the socket until it clicks into place.
  • Once the new battery is in place, close the cover of your device. You may need to press a button or flip a switch to turn your device back on.
