Everything You Need to Know About CR2032 Lithium Battery

When it comes to decoding lithium coin cell batteries, this approach can be used to cover a vast majority of them. As we mentioned earlier, there are subtle manufacturing variations in CR2032 batteries, and it's essential to understand these differences in order to choose the perfect replacement battery.

The next two digits in the code indicate the thickness of the battery, while the last two numbers represent the diameter measurement. In this case, the 'C' letter denotes the lithium manganese dioxide component, and the 'R' letter stands for its cylindrical or round shape. The codes on a battery type aren't just random numbers; they have meanings that offer valuable insights.

The negative terminal of this battery is typically made of either Lithium or zinc, while the positive terminal is composed of substances found in the air, such as cupric oxide, manganese oxide, oxygen, and more. On average, the diameter and height of this battery range from 5 to 25mm and 1 to 6 mm, respectively.

To identify the terminals, look for the '+' symbol, which indicates the positive connection. Once you find that, you'll be able to conveniently figure out both terminals. Generally, the negative terminal is an insulator at the top of the battery, while the positive terminal is a metal component at the bottom. The general configuration can be a bare cell accompanied by several attachments.

So, what are these for CR2032? Interestingly, all major manufacturing giants like Panasonic, Duracell, and Philips produce more than one type of CR2032 batteries. And, as with any battery or device, the most important question has to do with its manufacturing details.

Before you even think about an alternative or replacement equivalent for CR2032, it's crucial that you're well aware of this battery itself. By understanding the ins and outs of your CR2032 lithium battery, you'll be better equipped to make informed decisions when it comes to maintenance, replacement, or upgrading.
