History of CR1220 #
The CR1220 battery is a small, 3-volt lithium coin cell battery commonly used in small electronic devices such as watches, calculators, and car keys. It was first introduced in the early 1980s by the Japanese company, Maxell, and has since become a popular choice for many electronic devices due to its small size and long shelf life.
Typical Chemistry #
The CR1220 battery is a lithium-based battery, meaning it uses a combination of lithium and other materials to create an electrochemical reaction that produces energy. The CR1220 battery is composed of a lithium manganese dioxide cathode, a carbon anode, and a non-aqueous electrolyte. The cathode and anode are separated by a thin layer of electrolyte, which allows for the flow of electrons between the two electrodes. The electrolyte also helps to prevent the battery from short-circuiting.
Typical Use #
The CR1220 battery is commonly used in small electronic devices such as watches, calculators, and car keys. It is also used in medical devices, such as glucose monitors and hearing aids. The battery is also used in some toys and games, as well as in some remote controls.
The CR1220 battery is a small, 3-volt lithium coin cell battery. It has a diameter of 12.5mm and a height of 2.0mm, making it one of the smallest lithium coin cell batteries available. The battery has a nominal voltage of 3 volts and a capacity of 55 mAh. It has a shelf life of up to 10 years, making it an ideal choice for long-term storage. The battery also has a low self-discharge rate, meaning it will retain its charge for a long period of time. The battery is also resistant to temperature extremes, making it suitable for use in a wide range of environments.
