Battery cr2025 vs cr2032: Differences

When distinguishing between CR2025 and CR2032 batteries, several differences stand out. impacting their performance and suitability for various devices:

What is a CR2032 Battery

Thickness:

The most apparent physical difference between the two batteries is their thickness. The CR2025 is 2.5mm thick, while the CR2032 is slightly thicker at 3.2mm. This difference can affect whether a battery fits into a particular device’s battery compartment. with some devices specifically designed for one thickness over the other.

Capacity:

Another significant difference lies in their capacity. The CR2025 has a lower capacity of approximately 170mAh. whereas the CR2032 boasts a higher capacity of around 225mAh. This difference in capacity means that the CR2032 can store more energy. making it suitable for devices that require a longer-lasting power source.

Battery Life:

Due to its higher capacity, the CR2032 generally lasts longer than the CR2025. This extended battery life makes the CR2032 a better choice for devices. that consume more power or need to operate over more extended periods. without frequent battery replacements. The CR2025, while providing a reliable power source. need to replace more often in high-drain devices compared to the CR2032.
