Both CR2025 and CR2032 batteries are coin-cell batteries often used in small electronic devices, such as watches, remote controls, and key fobs. These button cell batteries share similarities in appearance and voltage but differ in terms of capacity and dimensions. In this article, we will explore the key differences between CR2025 and CR2032 batteries, allowing you to make an informed decision when selecting the appropriate battery for your specific needs.
Overview of CR2025 Battery
The CR2025 battery is a lithium coin cell battery with a nominal voltage of 3V and a capacity of approximately 170 mAh. These batteries are typically used in small electronic devices, such as watches, calculators, and heart rate monitors. With a diameter of 20 mm and a thickness of 2.5 mm, the CR2025 battery is slightly thinner than the CR2032 battery.
Overview of CR2032 Battery
The CR2032 battery is another lithium coin cell battery with a nominal voltage of 3V. However, it has a higher capacity of approximately 235 mAh, making it more suitable for devices with higher energy demands. With a diameter of 20 mm and a thickness of 3.2 mm, the CR2032 battery is slightly thicker than the CR2025 battery. Common applications for CR2032 batteries include watches, car key fobs, and small electronic devices.
Key Differences Between CR2025 and CR2032 Batteries
- Capacity: The most significant difference between CR2025 and CR2032 batteries is their capacity. The CR2032 battery has a higher capacity of around 235 mAh, while the CR2025 battery has a capacity of approximately 170 mAh. This higher capacity makes the CR2032 battery more suitable for devices with greater energy requirements.
- Dimensions: Both batteries have the same diameter of 20 mm, but the CR2032 battery is slightly thicker at 3.2 mm, whereas the CR2025 battery has a thickness of 2.5 mm. The difference in thickness may affect the compatibility of these batteries with certain devices.
- Applications: While both batteries can be used interchangeably in some devices, the CR2032 battery is generally more suitable for devices with higher power demands due to its higher capacity. On the other hand, the CR2025 battery is better suited for devices with lower energy requirements.
- Battery Life: Given its higher capacity, the CR2032 battery is likely to last longer than the CR2025 battery in most applications. However, the actual battery life will depend on the specific device and its energy consumption.
- Price: CR2032 batteries are usually slightly more expensive than CR2025 batteries due to their higher capacity. However, the price difference is generally minimal, and factors like brand and retailer can also affect the price.
