CR2032

The CR2032 is a common 3-volt lithium coin cell battery. The "CR" designation indicates that it is a lithium-manganese dioxide battery, which offers a high energy density and a long shelf life. The "2032" refers to its physical dimensions, with a diameter of 20 millimeters and a thickness of 3.2 millimeters. This specific size has made it a popular choice for a wide range of small electronic devices.

CR2032 batteries are frequently used in applications requiring a small, reliable power source. Common uses include powering computer motherboards for BIOS memory, key fobs, small remote controls, digital scales, calculators, and medical devices like glucose meters. Their stable voltage output and resistance to temperature fluctuations contribute to their widespread adoption.

These batteries are non-rechargeable and should be disposed of properly due to their lithium content. They are manufactured by numerous companies worldwide and are readily available in retail stores and online. The CR2032 is a workhorse in the battery industry, known for its consistent performance and affordability.
