Batteries have become an integral part of modern life, powering everything from remote controls to high-tech gadgets. Two common types of batteries used in small electronics are the CR2025 and CR2032 batteries. These batteries are both lithium coin cell batteries, but they have some significant differences that make them better suited for certain applications.
In this article, we’ll take a closer look at CR2025 and CR2032 batteries and compare them in terms of their size, capacity, voltage, and applications.
Differences Between CR2025 and CR2032 Batteries
Size
The first thing to note about CR2025 and CR2032 batteries is their size. The CR2025 battery has a diameter of 20mm and a thickness of 2.5mm, while the CR2032 battery has a diameter of 20mm and a thickness of 3.2mm. This means that the CR2032 battery is slightly thicker than the CR2025 battery.
Capacity
Another important difference between these two batteries is their capacity. The capacity of a battery refers to the amount of energy it can store and deliver over its lifetime. In general, the CR2032 battery has a higher capacity than the CR2025 battery. The CR2032 battery has a capacity of around 240mAh, while the CR2025 battery has a capacity of around 165mAh.
Voltage
The voltage of a battery is also an important consideration when comparing CR2025 and CR2032 batteries. The voltage of a battery determines the amount of power it can deliver to a device. Both the CR2025 and CR2032 batteries have a nominal voltage of 3 volts, which is the same as most other lithium coin cell batteries.
Applications
So, which battery is better suited for which application? In general, the CR2032 battery is better suited for applications that require higher capacity and longer life, such as computer motherboards, calculators, and remote controls. The higher capacity of the CR2032 battery means it can last longer and deliver more power to these types of devices.
On the other hand, the CR2025 battery is better suited for applications that require a lower capacity but a smaller size, such as small toys, LED lights, and glucose meters. The smaller size of the CR2025 battery makes it more suitable for these types of devices, and the lower capacity is sufficient to power them.
Conclusion
In conclusion, while CR2025 and CR2032 batteries are similar in many ways, they have some important differences that make them better suited for different applications. The CR2032 battery has a higher capacity and is better suited for applications that require longer life and higher capacity, while the CR2025 battery is better suited for applications that require a smaller size and lower capacity. When choosing between these two batteries, it’s important to consider the specific requirements of the device you’ll be using them in.
