CR2025 and CR2032 batteries are both coin cells, often used in watches, calculators, and other small electronic devices. Here are the main differences:
1. Size:
The main difference between the CR2025 and CR2032 lies in their dimensions. The “20” and “32” in their names stand for the battery’s diameter and height in millimeters. CR2025 has a diameter of 20mm and a height of 2.5mm while CR2032 has a diameter of 20mm and a height of 3.2mm. This makes the CR2032 slightly thicker than the CR2025.
2. Capacity:
Due to the difference in size, CR2032 batteries typically have a higher capacity than CR2025 batteries. CR2032 batteries typically have a capacity of around 220mAh, while CR2025 batteries typically have a capacity of around 165mAh. This means that the CR2032 battery can generally power a device for a longer period than the CR2025 before needing to be replaced.
3. Power:
Both batteries deliver 3 volts of power. However, due to its higher capacity, a CR2032 battery can deliver that power for a longer period of time.
4. Interchangeability:
While both batteries have the same diameter, their different thicknesses can cause compatibility issues. Some devices may be able to accept both sizes, but others may be designed specifically for one or the other. Always check your device’s manual before substituting one type of battery for another.
5. Weight:
The CR2032 is slightly heavier due to its larger size and higher capacity.
In summary, the main differences between these two batteries are their size, capacity, and potential interchangeability with certain devices. Always be sure to use the correct battery type recommended by the manufacturer to ensure optimal performance and prevent possible damage.
