CR2032 Coin Cell Battery
While they may look similar and serve similar purposes, there are distinct differences between these two types of batteries. If you’ve ever wondered which one to use or whether they are interchangeable, this article has you covered.
CR2025 Coin Cell Battery
Quick Summary
The CR2032 and CR2025 batteries are similar in many ways but differ in thickness, capacity, and lifespan. While they can often be used interchangeably, it’s important to consider the physical space available in your device and your power requirements.
The CR2032 offers a longer lifespan and is ideal for devices with adequate space, while the CR2025 is better suited for slimmer devices. Understanding these differences ensures you choose the right battery for your needs and maintain optimal device performance.
What Are CR2032 and CR2025 Batteries?
Both the CR2032 and CR2025 are lithium coin-cell batteries. They are designed to provide a stable and long-lasting power source for small devices that require minimal energy.
Key Differences Between CR2032 and CR2025
| Feature | CR2032 | CR2025 |
|---|---|---|
| Diameter | 20 mm | 20 mm |
| Thickness | 3.2 mm | 2.5 mm |
| Capacity | ~220 mAh | ~160 mAh |
| Voltage | 3V | 3V |
| Lifespan | Longer due to higher capacity | Shorter than CR2032 |
| Weight | Heavier | Slightly lighter |
Diameter
Both batteries have a diameter of 20 mm, making them the same width and capable of fitting into the same battery compartments.
Thickness
The CR2032 is 3.2 mm thick, while the CR2025 is 2.5 mm thick. This difference in thickness affects the overall capacity and energy storage.
Capacity
The CR2032 has a higher capacity of approximately 220 mAh, compared to the CR2025’s 160 mAh. This means the CR2032 can power devices for a longer time before needing replacement.
Voltage
Both batteries provide the same voltage of 3V, ensuring they deliver the same amount of power to devices.
Lifespan
Due to its higher capacity, the CR2032 lasts longer than the CR2025 under similar usage conditions.
Are CR2032 and CR2025 Interchangeable?
In many cases, CR2032 and CR2025 batteries can be used interchangeably, but there are a few considerations:
When They Are Interchangeable
- If the device’s battery compartment can accommodate the thicker CR2032 battery, you can replace a CR2025 with a CR2032 for longer battery life.
- If the device does not have strict thickness requirements, both batteries can fit and function properly due to their identical voltage.
When They Are Not Interchangeable
- Devices with tight battery compartments specifically designed for a 2.5 mm thickness may not close properly or accept the thicker CR2032 battery.
- Using a CR2025 in place of a CR2032 will result in shorter battery life due to its lower capacity.
When to Use CR2032 vs. CR2025
Use CR2032 If:
- The device has a larger battery compartment.
- Longer battery life is a priority.
- You want to reduce the frequency of battery replacements.
Use CR2025 If:
- The device requires a thinner battery.
- You have limited space in the battery compartment.
- The device consumes minimal power, making the lower capacity sufficient.
Tips for Replacing CR2032 and CR2025 Batteries
- Check the Device Manual: Always consult your device’s manual to determine the recommended battery type.
- Fit the Battery Properly: Ensure the battery fits securely in the compartment to maintain proper contact with terminals.
- Avoid Forcing a Fit: Forcing the wrong size battery into a compartment can damage the device or the battery.
- Store Batteries Safely: Store unused batteries in a cool, dry place to maintain their longevity.
Summary
Conclusion
Both CR2032 and CR2025 batteries are popular choices for small electronic devices, but they differ in thickness, capacity, and battery life.
While they share the same voltage and diameter, the CR2032 lasts longer due to its higher capacity, making it a better option for devices that require extended power.
On the other hand, the CR2025 is better suited for devices with limited space or lower power requirements. By understanding these differences and considering your device’s needs, you can ensure optimal performance and make an informed choice when selecting the right battery.
