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


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.


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.
