Product Description
Panasonic BR2032/BN 3V Lithium Carbon Monofluoride Battery
When your critical electronics require long-term reliability and stability, the Panasonic BR2032/BN (COMP-141) is the professional choice. Unlike standard "CR" series batteries, this "BR" series cell uses Lithium Carbon Monofluoride chemistry, making it uniquely suited for applications that demand a long service life and high-temperature resistance.
The "BR" Advantage
While standard lithium coin cells are great for everyday electronics, the BR2032 is engineered for the long haul. The Carbon Monofluoride chemistry provides a lower self-discharge rate and a much higher tolerance for heat. This makes it the preferred battery for memory backup (CMOS), industrial controllers, and medical devices where the battery may be required to last for many years without replacement.
Reliable Power in Demanding Conditions
With a 190mAh capacity and a steady 3V output, this cell ensures that your settings and data remain secure. Whether it’s powering a motherboard, a specialized medical instrument, or a high-end watch, the Panasonic BR2032/BN delivers consistent performance. Its pressure-contact termination style ensures a secure fit in standard 2032 battery holders.

Why Choose the BR2032 over a standard CR2032?
While standard CR2032 batteries are popular for household electronics, the Panasonic BR2032 is the industrial standard for critical backup applications. Here is why professionals choose the BR series:
- High Temperature Stability: Standard CR batteries are rated for up to 60°C. The BR2032 operates safely up to 85°C (185°F), making it ideal for engine sensors and hot server rooms.
- Decade-Long Reliability: With a self-discharge rate of less than 0.5% per year, this battery is designed to sit idle in a memory backup circuit for up to 10 years and still provide full power when needed.
- Stable Voltage Curve: The Carbon Monofluoride chemistry provides a flatter discharge curve, ensuring sensitive electronics receive consistent 3V power until the very end of the battery's life.
