How Long does CR2016 Run?


The typical shelf life of CR2016 batteries is generally cited as six years. However, there are claims from a battery manufacturer asserting that their single-use silver-zinc battery variant can extend that duration to ten years. As per watch manuals, a CR2016 battery is expected to power the device for approximately two years, especially in G-Shock watches.


Nevertheless, some individuals consider these estimates to be conservative approximations. Users who refrain from utilizing features like the auto EL light function, the hourly chime, or the alarm in their watches report real-world experiences suggesting that the battery life could extend to seven years or even more. These insights are based on the practical observations of users employing CR2016 batteries in their electronic timepieces.


Overview of CR2032 Battery


The CR2032 battery, recognized as a coin-shaped lithium-ion cell, delivers a 3-volt output and is commonly called the CMOS (complementary metal-oxide-semiconductor) battery. Widely employed for energizing a computer's BIOS or its real-time clock, this non-rechargeable (primary) battery has become ubiquitous in contemporary applications.

CR2016 vs. CR2032: Are they Interchangeable?


Capacity


CR2032 battery

The capacity is 240 mAh, providing approximately 10 hours of usage under an average load of 24 mA.


CR2016 battery 

The capacity of 90 mAh, delivering around 6 hours of usage with an average load of 15 mA.


Voltage


Both the CR2032 and CR2016 batteries are 3-volt lithium coin batteries.


Thickness


CR2032 battery

The CR2032 battery measures 3.2 mm.


CR2016 battery

The CR2016 battery has a thickness of 1.6 mm.


While the CR2016 and CR2032 vary in thickness, they share numerous similarities. Both belong to the 3-volt category and are non-rechargeable. It's essential to note, though, that their capacities diverge significantly. The CR2032 boasts a 240 mAh capacity, whereas the CR2016 lags with only 90 mAh. Consequently, the CR2032 can endure up to 10 hours, while the CR2016 manages approximately six hours, contingent on the power consumption.


Despite both batteries delivering 3 volts, their non-interchangeability stems from differing thicknesses. Attempting to substitute two CR2016s for a single CR2032 would yield 6 volts, posing a risk of damaging the connected device. Exercise caution to avoid unintended consequences.

Conclusion


The main difference between a CR2016 and a CR2032 battery lies in their capacities, with the CR2032 boasting approximately double the capacity of the CR2016. This results in an extended lifespan before requiring replacement. Both batteries operate on a 3-volt lithium-ion platform. Despite sharing the same nominal voltage, their dissimilarities in capacity and thickness render them non-interchangeable.


The CR2016, at 1.6mm thickness, contrasts with the 3.2mm thickness of the CR2032. Discerning the thickness of CR batteries is straightforward—examine the last two digits of their names. The larger CR2032 may not fit into compartments designed for CR2016 in most single-cell devices. Conversely, some devices may accommodate two stacked CR2016 batteries as an alternative to a single CR2032, achieving the correct size but yielding an incorrect voltage of 6V (3V+3V). Caution is advised against this, as it deviates from the recommended usage of a single CR2032 providing 3V.
