Why Using a CR2032 Instead of a CR2016 Might Work for Me

When I ran out of CR2016 batteries for my small electronic device, I wondered if a CR2032 could be a suitable replacement. Both batteries share the same diameter of 20mm, which means the CR2032 physically fits into the battery compartment designed for CR2016. This was the first reason I considered trying the CR2032—it’s convenient and readily available in most stores.

Another reason I found the CR2032 helpful is its higher capacity. The CR2032 generally offers about twice the mAh rating compared to a CR2016, which means my device could potentially run longer without needing a battery change. Even though the CR2032 is a bit thicker (3.2mm vs. 1.6mm), in some cases, the battery compartment can accommodate this extra thickness without issue, allowing me to extend the battery life without modifying the device.

However, I also made sure to check that my device could handle the slightly higher voltage and that the battery fit securely. In my experience, using a CR2032 in place of a CR2016 worked well as a practical solution when I needed a quick replacement, giving me peace of

Will A CR2032 Work For CR2016? My Buying Guide

Understanding the Difference Between CR2032 and CR2016

When I first looked at CR2032 and CR2016 batteries, I noticed they look very similar, but they aren’t identical. The main difference lies in their thickness. The CR2016 is 1.6mm thick, while the CR2032 is thicker at 3.2mm. Both have a diameter of 20mm, which means they fit in the same diameter battery compartment but differ in how much space they occupy.

Checking Compatibility With Your Device

Before deciding to use a CR2032 instead of a CR2016, I always check my device’s battery compartment and manual. Some devices have tight battery slots designed specifically for the thinner CR2016. Using a thicker CR2032 might cause the battery not to fit properly or prevent the device from closing securely.

Considering Voltage and Capacity Differences

Both CR2016 and CR2032 batteries provide the same voltage, typically 3 volts, so voltage won’t be an issue. However, the CR2032 has a higher capacity because of its larger size, meaning it can last longer. When I replaced a CR2016 with a CR2032 in a compatible device, I noticed the battery life improved.

Potential Risks of Using CR2032 in Place of CR2016

One thing I learned is that forcing a CR2032 into a battery slot meant for a CR2016 can damage the device or cause poor contact. The battery might also become loose or get stuck, making future replacements difficult. So, it’s important to ensure the battery compartment can handle the thicker size before making the swap.

My Recommendation on Making the Switch

If my device physically fits a CR2032 where a CR2016 was originally used, I feel comfortable using the CR2032 because of its longer life. But if the fit is tight or uncertain, I prefer sticking with the CR2016 to avoid any damage or malfunction.

Final Thoughts

In my experience, a CR2032 can work for a CR2016 only if the device accommodates the extra thickness. Always check the fit and manufacturer’s guidelines first. This approach helps me avoid surprises and ensures my devices keep running smoothly.
