What Are Batteries?
Batteries are a crucial part of our daily lives, powering everything from our smartphones to our bike computers.
The CR2032 battery is a type of non-rechargeable battery that's widely used today. It's a coin-cell battery that utilizes lithium chemistry.
These batteries are small, flat, and about the size of a nickel, making them a favorite among companies like PowerTap/CycleOps, Garmin, and Lezyne.
They're used in a variety of applications, including bike devices like head units, basic bike computers, transmitters, and heart rate monitors.
A CR2032 battery is also known by other names, such as 5004LC, BR2032, CR2032, DL2032, ECR2032, KCR2032, and KECR2032, depending on the manufacturer.
It's essential to understand the specifications of your device's battery to get the best use out of the battery. 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.
To identify the correct battery for your device, always check the markings on the existing battery or the battery cover of your device. The easiest way to do this is to remove the existing battery and examine the markings.
Specifications and Features
The CR2032 battery size is a popular choice for many portable electronics, and for good reason. It's a reliable and long-lasting option that can withstand a range of temperatures.
These batteries have a nominal voltage of 3 volts, which is a standard for many devices. They also have a capacity of around 235 mAh, which is sufficient for most small electronics.
The CR2032 battery size is designed to perform well in a variety of temperatures, from 0°C to 60°C. This makes it a great choice for devices that will be used outdoors or in extreme environments.
The dimensions of the CR2032 battery are 20mm in diameter and 3.2mm in height. This is slightly larger than some other battery sizes, but it allows for a higher capacity and longer lifespan.
Here are some key specifications for the CR2032 battery size:
- Nominal Voltage: 3V
- Capacity: ≈ 235 mAh
- Operating Temperature: 0°C – 60°C
- Height: 3.2 mm
- Width (Diameter): 20 mm
- Chemistry: Lithium Coin
It's worth noting that the CR2032 battery size is often used as a direct replacement for other battery sizes, such as 2032, ECR2032, BR2032, LM2032, 5003LC, DL2032, CR2032, KT-CR2032, and more. This makes it a convenient option for many users.
Battery Size and Packaging
The CR2032 battery size is a popular choice for many devices.
The main difference between CR2032 and CR2025 batteries is their thickness, with CR2032 being 0.7mm thicker.
A standard CR2032 can nominally deliver 225mAh, while the average CR2025 can nominally only deliver 160mAh.
This difference in capacity is due to the CR2032's slightly larger size.
Battery Uses and Applications
The CR2032 battery is a versatile power source used in a wide variety of devices. It's not uncommon to find them in car key fobs.
Many people use CR2032 batteries in their watches and calculators. You might be surprised to know that they're also used in computer motherboards.
Garage door openers, toys, and games often rely on CR2032 batteries for power. They're also found in door chimes, pet collars, and LED lights.
What Uses a Battery?
The CR2032 battery is used in a wide variety of devices and applications.
Computer motherboards rely on CR2032 batteries for power.
Car key fobs and watches are also powered by CR2032 batteries, making them convenient and portable.
Calculators and PDAs use CR2032 batteries to keep track of numbers and data.
Electronic organizers, garage door openers, and toys also use CR2032 batteries to function properly.
LED lights, sporting goods, and pedometers often require CR2032 batteries to operate.
Door chimes, pet collars, and calorie counters are just a few more examples of devices that use CR2032 batteries.
Medical devices, such as stopwatches, also rely on CR2032 batteries for accurate timekeeping.
Games and other electronic devices often use CR2032 batteries to provide power and functionality.
Can I Use a Battery Instead of CR2032?
You might be wondering if you can use a CR2025 battery instead of a CR2032 in a pinch. The answer is yes, but with some caveats.
The CR2025 and CR2032 can be used interchangeably with minimal effect, although the CR2032 will probably last slightly longer due to its higher capacity.
In an emergency or battery shortage situation, you can fold up a piece of aluminum foil or another conductor to fill up the extra space and ensure good contact with the battery and spring.
The difference between the two batteries is largely in their thickness, with the CR2032 being 0.7mm thicker than the CR2025.
The International Electrotechnical Commission (IEC) uses a specific code to name these batteries, which tells you about their physical attributes and chemistry.
Battery Lifespan and Differences
A CR2032 battery can last up to 10 years when properly stored, but its service life depends on the application. For example, a battery in a car key fob may last 4-5 years, while a more active device like the Apple Air Tag will only last about a year.
The lifespan of a CR2032 battery also varies depending on how often it's used. Devices with intermittent use, like a car key fob, can go longer without needing a replacement, while devices with constant use, like the Apple Air Tag, will drain the battery faster.
The CR2025 battery, a similar type, has a slightly shorter service life due to its lower capacity of up to 170mAh.

Battery Lifespan
A CR2032 battery can last up to 10 years on the shelf if stored properly, but its actual lifespan depends on the application.
In a car key fob, a CR2032 battery can last up to 4-5 years due to intermittent use.
A CR2025 battery, on the other hand, has a slightly shorter service life than a CR2032 due to its lower capacity of up to 170mAh.
The CR2025 battery is a non-rechargeable lithium coin cell that's 20mm in diameter and 2.5mm thick, with a high voltage of 3V.
A more active device like the Apple Air Tag, which uses a CR2032 battery, will only last about a year due to constant tracking.
Ideally, you'd want a battery made of high-quality materials, stored in a climate-controlled and dry area, with no physical damage to maximize its lifespan.

Battery Differences
Battery differences can greatly impact their lifespan and performance. The thickness of a battery is one of the main differences between battery types, with some being significantly thinner than others.
A CR2032 battery is 3.2mm thick, while a CR2025 battery is 2.5mm thick, a 0.7mm difference. This difference in thickness affects a battery's capacity to deliver current to a load.
A standard CR2032 can nominally deliver 225mAh, while the average CR2025 can only deliver 160mAh. This means a CR2032 battery can potentially last longer than a CR2025 battery.
Frequently Asked Questions
