Coin cell batteries are small and compact batteries that are widely used in various small electronic devices. These batteries are named coin cells due to their shape and size which resembles that of a coin. Among the various types of coin cell batteries available in the market, CR2032 and CR1632 batteries are two commonly used types. They are widely used in small electronic devices, such as watches, calculators, remote controls, and other devices that require low power consumption. Despite their similar appearance, these batteries differ in terms of their physical dimensions, voltage, and capacity, which can impact their suitability for different types of devices. In this article, we will take a closer look at the differences between CR2032 and CR1632 batteries to help you choose the right battery for your electronic device.
Differences Between CR2032 and CR1632
Physical Dimensions
The first noticeable difference between CR2032 and CR1632 batteries is their physical dimensions. CR2032 batteries have a diameter of 20mm and a thickness of 3.2mm, while CR1632 batteries have a diameter of 16mm and a thickness of 3.2mm. This means that CR2032 batteries are larger in size compared to CR1632 batteries. Therefore, you should choose the battery that fits the size requirements of your device.
Voltage
Both CR2032 and CR1632 batteries are 3V batteries.
Capacity
The capacity of a battery refers to the amount of charge it can hold and deliver over time. CR2032 batteries have a higher capacity than CR1632 batteries. Typically, CR2032 batteries have a capacity of around 220mAh, while CR1632 batteries have a capacity of around 120mAh. This means that CR2032 batteries can last longer than CR1632 batteries when used in the same device.
Applications
Both CR2032 and CR1632 batteries are commonly used in a variety of small electronic devices, such as calculators, remote controls, and watches. However, due to their different physical dimensions, voltage, and capacity, they may be better suited for different applications.
CR2032 batteries are ideal for devices that require high power consumption:
- LED lights
- Cameras
- Small motorized toys.
They are also suitable for devices that require a long lifespan, such as medical devices and smoke detectors.
CR1632 batteries, on the other hand, are better suited for devices that require less power consumption, such as:
- Remote controls
- Calculators.
They are also suitable for devices that require a compact design, such as key fobs and small digital thermometers.
Conclusion
In summary, both CR2032 and CR1632 batteries are 3V coin cell batteries that are commonly used in small electronic devices. While they may look similar, they differ in their physical dimensions, voltage, and capacity. Therefore, you should choose the battery that fits the size requirements and power needs of your device. If your device requires high power consumption and a longer lifespan, CR2032 batteries are the better choice. However, if your device requires less power consumption and a compact design, CR1632 batteries may be the better choice.
