PANASONIC Lithium battery BR-A 3V 1800mAh

This PANASONIC BR-A is a highly specialised 3-volt lithium battery in size A, developed for fail-safe power supply in the most demanding industrial applications. Based on the extremely reliable lithium polycarbon monofluoride technology (Li-(CF)n), this cell offers an exceptionally long service life and operational reliability, particularly in environments with extreme temperatures. As a loose cell ("bulk"), it is the first choice for powering PLC controllers and other critical industrial applications.

Highlights at a glance

• Maximum reliability: Developed for fail-safe buffering of program memories in CNC and PLC controllers.
• Extreme longevity: Very low self-discharge and a service life of up to 10 years or more.
• Extremely wide temperature range: Guarantees stable performance in a wide operating temperature range from -40 °C to +85 °C.
• Stable voltage: Constant 3-volt voltage for reliably powering sensitive electronics.
• High capacity: 1800 mAh for long-lasting autonomy in demanding applications.

Fail-safe power for industrial controllers

This PANASONIC BR-A battery is the preferred energy source for memory buffering (memory backup) in a wide range of machine tools and automation systems. It is typically used in programmable logic controllers (PLCs), industrial computers and metering systems (smart metering) exposed to extreme environmental conditions. Its main task is to reliably preserve the volatile program memory and system parameters in the event of a power failure or when the machine is switched off.

Superior lithium polycarbon monofluoride technology

The lithium polycarbon monofluoride technology (BR series) is the key to this battery's exceptional reliability. Compared to lithium manganese dioxide technology (CR series), it offers even lower self-discharge, a flatter discharge curve and superior performance at very high ambient temperatures, as are often found in industrial machine control cabinets. This guarantees maximum operational reliability throughout the long service life.

Developed for professional applications

This battery is designed as a direct replacement and OEM component. As a highly specialised single cell, the BR-A is optimised for industrial further processing and assembly into battery solutions. Its robust construction and high quality ensure process-safe integration into end devices for permanently reliable operation.

FAQs about the PANASONIC BR-A battery pack

What is the main advantage of BR technology over CR technology?

BR technology (lithium polycarbon monofluoride) is designed for maximum reliability and longevity at extreme temperatures. It has an even lower self-discharge than CR technology and a very stable voltage over almost the entire service life. It is the first choice for critical, low-maintenance industrial applications. In return, CR technology often offers higher pulse load capability.

Is this battery pack rechargeable?

No. This is a lithium primary battery. Under no circumstances should it be recharged. Attempting to charge is extremely dangerous and can lead to fire or explosion.

How is this cell integrated into a device?

As an industrial raw cell, the BR-A is usually assembled with welded solder pins or tabs in order to solder it securely onto a circuit board. It can also be used in special battery holders designed for the A size.

How should this battery be disposed of?

Batteries must not be disposed of in household waste. As an industrial battery, it is subject to the provisions of the Battery Act. Please take the empty battery to the designated industrial or municipal collection points to ensure proper and environmentally friendly recycling.
