Key Differences
The CR2032 and CR2016 are both coin cell batteries, used in small electronic devices such as watches, calculators, and key fobs. The main difference lies in their dimensions and capacity. CR2032 batteries have a diameter of 20mm and a thickness of 3.2mm, while CR2016 batteries are also 20mm in diameter but only 1.6mm thick. This difference in size directly impacts their capacity and, consequently, their lifespan in devices.
Both types of batteries are 3-volt lithium cells, but the CR2032 typically offers a higher capacity around 220 to 250mAh, compared to the CR2016's 80 to 90mAh. This higher capacity means that CR2032 batteries can power devices for a longer period than CR2016 batteries before needing replacement.
The choice between these batteries often comes down to the device's design requirements. Devices designed for longer use without battery replacement will typically use CR2032 batteries, while those with smaller battery compartments might opt for the thinner CR2016, sacrificing battery life for a slimmer profile.
In terms of compatibility, some devices can accommodate either battery type if the battery compartment allows for the difference in thickness. However, using a CR2016 in a device designed for a CR2032 might lead to shorter device operation time, and conversely, a CR2032 might not fit in a compartment designed for a CR2016.
Despite their differences, both battery types are widely used across various devices due to their reliability and long shelf life. Choosing between them depends largely on the device's power needs and physical constraints.

Common Curiosities
Why would a device use a CR2016 over a CR2032?
Devices requiring a slimmer profile for aesthetic or design reasons might prefer the thinner CR2016.
How long do CR2032 batteries last compared to CR2016?
CR2032 batteries generally last longer due to their higher capacity.
Can CR2032 and CR2016 batteries be used interchangeably?
They can be if the device allows for the size difference, but performance may vary.
Are CR2032 and CR2016 batteries the same voltage?
Yes, both types are 3-volt lithium batteries.
How do I know which battery type my device requires?
Check the device's manual or the existing battery's label for the recommended type.
Is there a significant price difference between CR2032 and CR2016 batteries?
Price differences are minimal, but CR2032s might be slightly more expensive due to their higher capacity.
Which battery should I choose for a device requiring long-term use without replacement?
The CR2032 is better suited for long-term use due to its higher capacity.
What is the main difference between CR2032 and CR2016 batteries?
The main difference is their thickness and capacity, with the CR2032 being thicker and having a higher capacity.
Can I replace a CR2032 with two CR2016 batteries to increase device runtime?
Only if the device is designed to accommodate the physical and electrical configuration, but this is not common.
Can using the wrong type of battery damage my device?
Using a thinner battery might not damage your device, but it may lead to poor performance. Using a thicker battery might not fit or close the battery compartment properly.
Are CR2032 and CR2016 batteries recyclable?
Yes, both types should be recycled properly to avoid environmental harm.
What happens if I use a CR2016 in a device designed for a CR2032?
The device might work but expect a shorter runtime due to the lower capacity of the CR2016.
Why do some devices require the use of two CR2016 batteries instead of one CR2032?
Some designs may use two CR2016s for form factor reasons or to achieve a certain voltage by stacking them.
Do both battery types have the same shelf life?
Yes, both types have a long shelf life, often up to 10 years, due to their lithium chemistry.
Are there devices that specifically recommend one battery type over the other?
Yes, manufacturers typically specify the battery type that optimizes performance and design compatibility for their device.
