Button battery is a small, flat cylindrical single-cell battery made of metal. It is mainly designed for portable electronic devices, such as toys, watches, computers, etc. The typical model of this battery is CR2032 button battery.
Coin batteries are an essential component in personal computers as they allow them to retain certain system settings after the system is shut down.

CR2032 button cell or lithium battery is a small round battery used in different high-power electronic devices such as computers, watches, hearing aids, and blood glucose monitors.
In CR2032 coin cells, "CR" is a chemical classification of the battery, with the first two digits indicating its diameter (20mm), while the remaining digits indicate its thickness or height in tenths of a millimeter (3.2).

Compared with alkaline batteries, button batteries have a longer service life, are lightweight, and have a wide operating temperature range, but cost slightly more. These types of batteries provide a long lifespan to 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 is durable and long-lasting in all climates, then coin batteries are a good choice.
