The BR2032 lithium coin cell is based on lithium poly-carbon monofluoride (Li-(CF)n) chemistry, designed for long-term, low-drain applications. Compared to the more common CR2032 (Li-MnO₂), the BR2032 offers lower capacity but significantly lower self-discharge, ensuring stable performance in devices where long shelf life and reliability are critical.

With a nominal voltage of 3V and a capacity of ~190mAh, the BR2032 maintains consistent voltage output over extended use. Its 10+ year shelf life, temperature stability (-30°C to +85°C), and low internal resistance make it an excellent choice for real-time clocks (RTC), memory backup systems, remote sensors, and medical electronics.

The BR2032 is a non-rechargeable primary coin cell, available from leading manufacturers such as Panasonic, Renata, and Maxell, with optional PCB-mounted pin or tab versions for easy integration.
