Order now A98L-0031-0012 GE Fanuc 3V Lithium Backup Battery
Order now A98L-0031-0012 to safeguard your machine’s critical operational data and prevent catastrophic memory loss. The GE Fanuc A98L-0031-0012 is a high-capacity, 3-Volt Lithium backup battery engineered specifically for industrial CNC memory retention and Absolute Pulse Coder (APC) positioning systems. In Fanuc architectures, this battery is the only line of defense keeping the SRAM alive when the main facility power is disconnected. It retains your machine’s ladder logic, pitch error compensation tables, macro variables, and complex part programs. Furthermore, when installed on Alpha series servo amplifiers, it keeps the absolute encoders powered so the CNC controller never forgets the physical location of its axes. Allowing this battery to deplete will result in a total loss of machine coordinates and parameters, forcing hours of expensive downtime for zero-return recalibration and factory software reloads. Securing a fresh OEM replacement ensures your factory floor remains productive and protected.

Expert Preventive Maintenance Tips
The golden rule of Fanuc CNC maintenance is strict battery management. The A98L-0031-0012 should be replaced annually as part of a rigorous preventive maintenance schedule, regardless of whether a low battery alarm is present. When replacing this battery, the CNC machine must be powered ON. If you disconnect the old battery while the main power is off, the SRAM memory will instantly wipe, or the absolute encoders will lose their reference points, triggering an immediate APC Alarm (Alarm 300 or similar). Locate the battery box—which may be mounted on the main CPU rack or clipped to the front of the servo amplifier module—carefully unclip the 2-pin connector, and plug the new battery in before removing the old one if dual slots are provided, or swap them swiftly while control power sustains the memory.
Frequently Asked Questions (FAQs)
What does a flashing BAT indicator on my CNC screen mean? The «BAT» warning signifies that the voltage of your A98L-0031-0012 battery has dropped below the critical safe threshold. You have a very limited window (often just a few days) to replace the battery before total data loss occurs upon the next power-down.
Can I use a commercial off-the-shelf 3V battery instead? While the core chemistry might be similar, commercial batteries lack the exact internal resistance profiling and the specialized, vibration-resistant 2-pin Fanuc connector required for reliable industrial operation. Always use the specified OEM part.
Where is this battery typically located on the machine? Location varies by machine builder. It is most commonly housed behind the CNC screen on the main CPU motherboard, or in a black plastic cartridge attached to the front face of the Alpha Servo Amplifier Modules in the electrical cabinet.
