CR2032 batteries, commonly known as coin or button cell batteries, are small lithium batteries. They are characterized by their manganese dioxide lithium composition, which makes them suitable for a wide range of devices. Typical applications include keyfobs, small remotes, scales, wearables, sensors, and various medical devices such as glucometers and digital thermometers. Sports devices like heart rate monitors and bike accessories also frequently use these batteries.
Panasonic is a notable brand in this category, offering CR2032 batteries that use lithium manganese oxide technology. These batteries provide a nominal voltage of 3V and a capacity of 210mAh. When compared to similar models like CR2025 or CR2016 batteries, CR2032s typically offer a higher capacity, enabling more powerful performance. This makes them more suitable for devices that require a bit more energy, like car remotes and motherboard components.
The physical dimensions of these batteries are also important. Each cell is usually about 20 millimeters in diameter and 3 millimeters thick, resembling a small, flat disc. This compact size allows them to fit into a variety of small electronic devices. Duracell, another leading brand, offers CR2032 batteries with child safety features and a pack size of eight, highlighting the widespread demand and application of these batteries.
In summary, CR2032 batteries are essential components in many modern electronic devices, appreciated for their reliability, compact size, and efficient energy output.
