CR1220 batteries make up the core of many modern electronics and offer great versatility and efficiency, which we will explore in this guide.

What is a CR1220 Battery?

In small, low-power electronic devices, CR1220 batteries are common lithium coin-cell batteries. With a diameter of 12 mm and a thickness of 2.0 mm, this battery operates at 3 volts, and is typically rated to hold about 35-40 mAh. As a result, it delivers consistent and stable power for a long period of time thanks to its lithium manganese dioxide (LiMnO2) chemistry. Lithium manganese dioxide batteries are described by the letters "CR" in their names, and the numbers "1220" describe the size (12 mm diameter and 2 mm thickness). CR1220 batteries are ideal for devices that are limited in space but need long-lasting performance.

A CR1220 battery can last up to 10 years without significant power loss in storage thanks to its high reliability. With this feature, it is ideal for devices that aren't constantly used, like wrist watches, calculators, and key fobs. These devices can be powered effectively for extended periods of time due to its stable voltage output. The compact design of the CR1220 also makes it a favorite choice for both manufacturers and consumers in electronic gadgets where weight and size are critical factors.
