CR2032 vs CR2025: What is the Difference?

The CR2032 and CR2025 batteries are widely used in small devices such as beepers, car keys, remote controls, and more. Both provide reliable energy capacity, but they have some important differences.

Technical Specifications

When comparing their specifications, we find that the CR2032 and CR2025 share the same diameter of 20 mm and a nominal voltage of 3 volts. However, they differ in height:

• CR2032: 3.2 mm (0.126 inches)
• CR2025: 2.5 mm (0.098 inches)

This difference in height means that the CR2032 has a greater energy storage capacity.

Capacity

• CR2025: 180 mAh
• CR2032: 225 mAh (55% more)

Usage Recommendations

The choice between the CR2025 and the CR2032 should be based on the device's specifications. Using the wrong battery can cause problems:

• Using a CR2032 instead of a CR2025: The greater height of the CR2032 can damage the device's contacts, rendering it unusable. It is crucial to verify that the battery is compatible with the device.

• Using a CR2025 instead of a CR2032: The shorter height of the CR2025 can result in insufficient contact, preventing the device from functioning.

Conclusion

Although both batteries have a similar price and many shared characteristics, it is essential to use the specific battery that your device requires. This will ensure optimal performance and avoid potential damage.
