Coin cell batteries are ubiquitous in today’s technology, powering a variety of devices ranging from simple calculators to advanced medical equipment. Among the many types of coin cell batteries available on the market, the CR1616 and CR1620 are two of the most commonly used ones. These batteries share some similarities in terms of their physical appearance and voltage, but there are also some crucial differences between them that may impact their suitability for particular applications. In this article, we will explore these similarities and differences in-depth to help you determine which battery is the right choice for your device.
Differences Between CR1616 and CR1620
Physical Dimensions
The first difference between the CR1616 and CR1620 batteries is their physical dimensions. The CR1616 battery measures 16mm in diameter and is 1.6mm thick, while the CR1620 battery is slightly larger, measuring 16mm in diameter and 2.0mm thick. While the size difference may seem insignificant, it can be critical in determining which battery to use in your device.
Capacity
Another important factor to consider when comparing the CR1616 and CR1620 batteries is their capacity. The capacity of a battery is measured in milliampere hours (mAh) and refers to how long the battery can power a device before needing to be replaced. The CR1616 battery has a capacity of approximately 50mAh, while the CR1620 battery has a capacity of approximately 70mAh. This means that the CR1620 battery can power a device for a longer period than the CR1616 battery.

Voltage
The voltage of a battery is another crucial factor to consider when comparing the CR1616 and CR1620 batteries. The voltage of these batteries is typically 3 volts, which is standard for most small electronic devices. However, it is essential to ensure that the voltage of the battery you choose is compatible with the voltage requirements of your device.
Application
The application of the device is another factor to consider when choosing between the CR1616 and CR1620 batteries. The CR1616 battery is commonly used in devices that require a low level of power, such as calculators and key fobs. On the other hand, the CR1620 battery is often used in devices that require a higher level of power, such as digital watches and remote controls.
Price
Finally, the price of the CR1616 and CR1620 batteries is an essential factor to consider. The price of these batteries can vary depending on the brand and the quantity you purchase. However, generally, the CR1620 battery is slightly more expensive than the CR1616 battery due to its higher capacity.
Conclusion
In conclusion, when choosing between the CR1616 and CR1620 batteries, several factors must be considered, including physical dimensions, capacity, voltage, application, and price. While the CR1620 battery has a higher capacity and is more suitable for devices that require a higher level of power, the CR1616 battery is more suitable for devices that require a lower level of power. Ultimately, the right battery for your device will depend on its specific requirements and the features that are most important to you.
