The 9 Best CR2032 Battery Choices for 2021

Many of today’s portable devices use a CR2032 battery to obtain the power they need. Even if you’ve never changed out these coin-shaped batteries in the past, there is an excellent chance that you have multiple devices that require this size.

Several benefits become available when you compare the CR2032 battery with the standard alkaline-based products in the marketplace. You can achieve higher voltages by stacking these cells into tubes, making it one of the most versatile options that are on the market today.

Although the construction of CR2032 batteries is inexpensive and small, stacking is not typically performed anymore. Most of the products with this design are non-rechargeable and used as the primary battery in electronic equipment.

With several different brands and manufacturers creating this option, finding the best CR2032 battery to meet your needs can sometimes be challenging. We’ve carefully chosen the best products in this category, compared their features, and noted individual advantages and disadvantages for you to consider.

Best CR2032 Battery Reviews

CR2032 batteries are remarkably affordable. Most brands offer them at a price that averages around $1 per item. That means you’ll find most of them get packaged into sets of 2, 6, or 10 batteries.

1. Duracell CR2032 Battery

Duracell is one of the world’s leading manufacturers of batteries. Although it is now a wholly-owned subsidiary of Berkshire Hathaway, it was once a small business operating as the P.R. Mallory Company in the 1920s.

The term “Duracell” became a brand in the 1960s when the company combined the words “durable cell” into a company name. These batteries continued to bear the Mallory branding until 1980.

These batteries come with Duracell’s Duralock Power Reserve™. You’ll know when each one was made because the expiration date is on the front of the package. You can use them anywhere, in any device, that calls for the use of a CR2032 battery.

Duracell also makes a standard 2032 battery without the Duralock Power Reserve, so you’ll need to take care when purchasing from this brand. The regular CR2032 is also compliant as DL2032 batteries.

Pros:

  • The batteries come with a corrosion-resistant triple-layer casing that prevents leaking and rust.
  • You can use these CR2032 in a variety of weather conditions, including when you’re out in the rain.
  • These batteries can serve as a replacement for DL2032 options without sacrificing performance.
  • The packaging separates the cells effectively so that you can have the maximum lifespan with this product.

Cons:

  • There can be some confusion on the packaging of the batteries. Look for the expiration date on the front of the container so that you know you’re purchasing the correct item.
  • The price of these batteries is about 50% more than what you’ll pay with other brands.
  • It can be challenging at times to get individual cells out of their packaging without adversely impacting the future performance of the unit.

2. Panasonic CR2032 Battery

The Matsushita family founded the company responsible for Panasonic products in 1918. It was initially a producer of lightbulb sockets, but the organization has grown to become a global brand that produces a variety of electronic devices.

What Is a CR2032 Battery?

The CR2032 battery coin is the most common size used in a variety of portable devices. You can find this size in watches, key fobs, and fitness appliances. It features a low self-discharge rate, which means you can achieve a shelf life of up to 10 years with some brands.

This battery provides a high voltage rate of 3V, giving you plenty of power in an ultra-compact design. It is one of the highest-rated and safest-performing options that’s available today.

Are All CR2032 Batteries the Same?

All CR2032 batteries share some characteristics with one another. They are coin-shaped (sometimes referred to as a “button” battery), with a diameter of 20 millimeters, and a height of 3.2 mm – although some physical differences can be found in different brands. All manufacturers use manganese dioxide lithium for the product’s chemistry.

Button batteries like these receive their name because of their dimensions. If you need a CR2025 battery, then you would purchase a product that has a 20 mm diameter and 2.5 mm height.

The CR2032 battery also comes with a voltage of 3V, with open-circuit voltages of 3.6V. There can be some variations by brand because of differences in the manufacturing process of the battery. This difference can result in some capacity variations.

How Do CR2032 Batteries Work?

A CR2032 battery uses the combination of manganese dioxide and lithium to create a chemical reaction.

The lithium side oxidizes as the manganese dioxide starts deducing, causing electricity to flow through the device. When the chemical reaction is over, then the battery typically requires a replacement because of its design. Most brands do not produce a rechargeable version of this size.

Most CR2032 batteries use stainless steel for the case because it does an excellent job of preventing electrolyte leakage. These workhorses do well in ultra-low power subsystems, especially when an alternative power supply is available for use.

How Long Does a CR2032 Battery Last?

The typical CR2032 battery can last between 12-24 months in most portable devices. Each cell is a little different, even within the same brand, so an exact outcome isn’t predictable.

Most CR2032 batteries can last for 8-10 years before being used while maintaining 90% of their base power.

Almost all CR2032 batteries have either an expiration or production date printed on their packaging. Some get engraved on the casing of the item. A few manufacturers have taken to writing both of these dates for consumers to consider.

Some batteries use a manufacturing code instead of an actual date to indicate when it was created, or the unit should expire. The first letter represents the country of origin, while the second shows the month the battery was produced, and the third indicates the year.

If you receive a battery with a code that starts ORN, then you know it was made in the United States in January 2014. That means it may have an expiration date between 2019-2024, depending on the specifications offered by the manufacturer.

How the battery gets used will also impact its lifespan. If the CR2032 battery must provide 3.0 mA consistently, then its maximum time of use will only be 17% of its published rating. If a circuit can’t function below 2V, then it will add even more drain to the usable capacity.

What Is the Difference Between a CR2032 vs. a 2032 Battery?

The CR designation for the CR2032 battery indicates that it uses a lithium manganese dioxide reaction. You can find other 2032 cell chemistries available on the market that use different processes to supply power.

  1. A BR designation indicates that the battery uses lithium and carbon monofluoride.
  2. ML batteries use the same lithium manganese dioxide structure, but it flips their placement so that the lithium compound is on the negative electrode.
  3. A VL battery uses lithium-ion chemistry to provide energy.
  4. LIR batteries have a higher voltage with rechargeable chemistry. These 2032 batteries are usually found powering memory backups, electronic watches, and vehicular security systems.

All 2032 batteries have a diameter of 20 mm and a height of 3.2 mm. Although some equipment may have a specific preference for CR designation batteries, most of them are interchangeable.

What Is the Best CR2032 Battery for Your Needs?

Buying batteries online can be a challenging process. Even if you buy them directly from the manufacturer, you have no way to guarantee that what you’re receiving is a used item.

One of the best ways to check if your batteries are authentic is to see if a foil backing is present on your package. Your CR2032s should also ship inside of individual blisters. If you encounter either issue with your purchase, then you should return the ordered product.

Today’s CR2032 batteries provide a powerful punch that gives our portable devices the energy they need. It is an affordable and convenient way to manage a busy lifestyle, keep track of your health, and much more. Each brand has specific pros and cons to consider with this coin-shaped battery, so consider each carefully before deciding on a practical solution you can use at home.
