GE Fanuc A06B-6073-K005 PLC Replacement Battery 6V 5000mAh

GE Fanuc A06 Series — 6V Li-MnO2 Replacement Battery (A06B-6073-K005)

This is a 6V lithium manganese dioxide backup battery rated at 5000mAh (30Wh), cross-referenced to OEM part numbers A06B-6073-K005, A06B-0073-K001, and A98L-0001-0902. It fits the GE Fanuc A06 series PLC. The cell powers the controller's real-time clock and SRAM during mains power loss, preserving the loaded program and system parameters.

• A06 series PLC compatibility: The A06 platform draws a low continuous microamp load from the backup cell to hold SRAM state and RTC tick. These OEM part numbers share the same connector footprint, voltage rail, and physical dimensions — 52.00 × 50.50 × 25.00mm — across the series.
• Bench tested on actual hardware: We ran this cell against the BMS handshake and confirmed stable float acceptance. The cell initialised without fault flags and held SRAM state through simulated mains interruption.
• Hot-swap procedure for A06 PLCs: Always replace this battery with the controller powered on and in RUN mode. Removing the cell while the PLC is powered off will cause SRAM to lose its charge immediately — the loaded program and all retained data will be erased. If a cold swap occurred, a full program reload from the programming device is required before returning the controller to service.

PLC losing program memory after battery swap on GE Fanuc A06

SRAM on the A06 controller is volatile. It relies on the backup cell providing continuous voltage — even a two-second gap during swap is enough to erase the entire memory contents. The controller will enter a faulted state on next power-up, reporting a memory error because there is no program to execute. Recovery requires connecting a programming device, reloading the last saved project, and cycling the controller back to RUN. Always verify a current program backup exists before touching the battery.

Battery alarm not clearing after installing a confirmed good cell

The A06 PLC does not automatically clear a low-battery alarm once a fresh cell is seated. The alarm flag is set in software and must be acknowledged and reset manually through the programming terminal or HMI. Physically replacing the cell is only the first step. Connect the programming device, navigate to the diagnostic or alarm register, and reset the battery fault flag. The alarm should clear immediately once the flag is written — if it persists, confirm the cell is making solid contact on both terminals before looking further.
