From key fobs to remotes, coin cell batteries are a common power source. One of the most popular types is the CR2032 battery. In today’s article, we’re answering some of the most frequently asked questions about the CR2032 battery to help you understand where it’s used, how long it lasts, and how to manage it properly.
Is CR2032 the Same as CR3032?
No, they are not the same. While both are 3V lithium coin batteries, they differ in size:
- CR2032 is 20 mm in diameter and 3.2 mm thick
- CR3032 is 30 mm in diameter and 3.2 mm thick
They are not interchangeable unless your device specifically allows for different sizes.
What is a CR2032 Battery Used For?
The CR2032 battery is commonly used in:

- Remote controls
- Watches

- Calculators
How Long Should a CR2032 Battery Last?
Typically, a CR2032 battery can last between 1 and 3 years depending on usage and device type. In low-drain devices like key fobs, it may last closer to 3 years.
What Can I Replace a CR2032 Battery With?
The best replacement for a CR2032 is another CR2032 battery. While other coin cells like CR2025 or CR2016 may fit in the battery compartment, they have different thicknesses and lower capacity, so it’s best to stick with the exact type.
What is the Shelf Life of CR2032 Batteries?

Does Dollar Tree Sell CR2032 Batteries?
