Weight1.7 g2.9 g

The main difference between the two is their size and capacity. CR2016 batteries are thinner and have a diameter of 20 millimeters, while CR2032 batteries are slightly thicker and have a diameter of 32 millimeters. As a result, CR2032 batteries have a higher capacity and can last longer than CR2016 batteries in the same device.

Both types of batteries are non-rechargeable and must be replaced when they can no longer hold a charge. They are commonly available at electronics stores and online retailers.

It is important to note that CR2016 and CR2032 batteries are not interchangeable and can only be used in devices that are designed to accept the specific size and type of battery. Always check the manufacturer’s recommendations or the device’s documentation to determine the correct battery type.
