FAQ

How often should I replace my BR-2/3A4F battery?

We recommend replacing every 1–2 years in active systems to prevent unexpected downtime, even though shelf life is up to 10 years.

Is this battery compatible with my GE Fanuc controller?

Yes. It is a direct replacement for A06B-6114-K504, A98L-0031-0025, BR-2/3AGCT4A, BR-2/3AF, and related part numbers.

Can I use this battery in extreme temperatures?

Yes. The BR-2/3A4F operates reliably between –60 °C and +85 °C.

How can I tell if I have a counterfeit battery?

Authentic USA-assembled units have clear English labeling and genuine Panasonic cells. Labels with Chinese characters are likely counterfeit.

Do I need special tools to install it?

No. The battery should be changed while the machine is powered on to avoid losing data or encoder positions, just disconnect the old battery, and connect the new one to the matching plug.

It is crucial to consult the machine's manual or a qualified technician if you're unsure about the specific procedure for your machine.

Note: Do not power down the system, your PLC requires constant power in order to save your settings.  Powering down your equipment AND removing the back-up battery will effectively cause the controller board to loose all of your settings.
