CR2016 vs. CR2032: Difference Between

The CR2016 and CR2032 are both coin cell batteries, commonly used in small electronic devices like watches, calculators, and car key fobs. Despite their similar appearances and functionalities, there are several key differences between the two.

Diameter and Thickness

CR2016: This battery measures 20mm in diameter and 1.6mm in thickness, which explains the '2016' in its name (20mm x 1.6mm).

CR2032: Slightly thicker than the CR2016, this battery also measures 20mm in diameter but is 3.2mm thick. The '2032' denotes its dimensions (20mm x 3.2mm).

Capacity and Voltage

Voltage: Both the CR2016 and CR2032 have the same voltage of 3 volts, which is typical for lithium coin cells.

Capacity: There is a significant difference in capacity between the two. The CR2032 generally offers around 240 mAh (milliampere hours), while the CR2016 provides about 90 mAh. This means the CR2032 can store more energy and is suitable for devices that require longer battery life.

Applications

CR2016: Due to its thinner profile, the CR2016 is ideal for smaller, slimmer devices where space is limited. It's often used in thinner wristwatches, small calculators, and some healthcare devices.

CR2032: This battery's larger capacity makes it more suitable for devices that have higher power demands or are used more frequently. It is commonly used in computer motherboards as a CMOS battery, portable medical devices, and higher-end digital watches.

Compatibility and Interchangeability

Although both batteries have the same diameter, they are not interchangeable due to their difference in thickness. Devices designed for a CR2032 battery will not properly accommodate a CR2016 due to the gap in the battery compartment, potentially causing issues like loose connections that can lead to device malfunction.

Durability and Shelf Life

Both types typically offer similar shelf lives of up to 10 years due to the stable lithium technology used in their manufacture. However, the actual operational life once in use can vary greatly depending on the device's energy demands.

CR2016 vs. CR2032: Similarities Between

The thickness of the CR2016 and CR2032 may vary, but they are identical in some ways. They are both 3 volt versions and both are non-rechargeable. Since the voltage is the same, the CR2016 and CR2032 are interchangeable in some cases. However, since they have different capacities, and therefore different run times, this can cause problems. The CR2016 cannot provide the amount of power that the CR2032 provides, and some devices may not even work properly.

Conclusion

while CR2016 and CR2032 batteries might appear similar at first glance due to their identical voltages and cylindrical shapes, their differences in size and capacity have significant implications for their practical applications and interchangeability. The CR2032's thicker and more capacious design makes it suitable for more power-intensive devices or those requiring longer battery life, whereas the thinner CR2016 is ideal for more compact and low-power devices. Understanding these nuances can help users make informed choices about which battery type is best suited for their specific needs. To ensure optimum performance and longevity of both your smartphone and the battery itself, always take into account the characteristics of the battery and the needs of your device before making a substitute.
