CR2032 button battery pin configuration_Specification parameters_Application circuit

A button battery is a small, flat cylindrical single-cell battery made of metal, mainly designed for portable electronic devices, such as toys, watches, computers, etc. The typical model of this battery is CR2032 button battery.

Button batteries are essential components in personal computers because they allow them to retain certain system settings after the system is turned off. Most button cells consist of manganese dioxide (alkaline), silver oxide (Sio2) or lithium (Li), and depending on how they are used, can last up to several years. In this article, the editor briefly introduces the pin configuration, specification parameters and application circuit of the CR2032 button battery.

  basic concept

A CR2032 button cell or lithium battery is a small round battery used in different high power electronic devices such as computers, watches, hearing aids, blood glucose monitors. The CR2032 coin cells are compact in size, with a height of 1 to 6 mm and a diameter of 5 to 25 mm.

In a CR2032 coin cell, "CR" is a battery chemical classification, the first two digits indicate its diameter (20mm), while the remaining digits indicate its thickness or height in tenths of a millimeter (3.2). These coin cell batteries are generally designed by the major battery manufacturing companies.

Compared to alkaline batteries, button cells have a longer lifespan, are lighter in weight, and have a wider operating temperature range, but are slightly more expensive. These types of batteries provide a long lifespan for the device that uses it.

The service life of CR2032 button battery mainly depends on different factors, such as temperature, storage conditions, physical damage, material quality, storage time, etc. If you're looking for a battery that's made from high-quality materials and that's durable and long-lasting in all climates, then a coin cell is the way to go.
