FANUC backup power cell using the SANYO CR17450SE-R 3 V lithium chemistry, supplied as a prewired 2-position JAE female plug for direct connection to FANUC i-series controls. This spare part maintains SRAM contents so programs, parameters and offsets remain intact when the control is powered off, making it a routine maintenance item for FANUC Series 16i, 18i and 21i as well as CNC i platforms.

Built for the FANUC ordering code A98L-0031-0012, this drop-in replacement fits the yellow backplane assembly commonly identified as A02B-0200-K102. The cylindrical cell follows the 4/5A format at approximately 45 x 18 mm, and arrives with the correct keyed connector to avoid polarity mistakes during field replacement.

In the CNC architecture this battery keeps volatile memory alive on the control board. A low-voltage message on the operator panel indicates service is due, and maintenance teams typically change this spare with the control powered on to avoid memory loss. The unit’s 3 VDC nominal output and 2200 mAh capacity support long backup intervals under normal control load.

For machine-tool shops running legacy FANUC i-series controls, this part is a practical stocked spare that prevents unplanned data loss after shutdowns. It is widely used on machining centers, lathes and grinders equipped with the i-series backplane where the plug-in harness simplifies a quick field swap during scheduled service.

Reference: A98L-0031-0012

Manufacturer: FANUC

Product type: FANUC Battery

Main function: Memory backup cell for FANUC i-series CNC controls, preserving programs, parameters and offsets during power-off

Applications: FANUC 16i, 18i, 21i and CNC i systems installed on the yellow backplane, commonly associated with A02B-0200-K102

Key technical data: 3 VDC primary lithium cell, approx. 2200 mAh capacity, cylindrical 4/5A size about 45 x 18 mm, pre-terminated 2-position JAE female connector, Japan-made, suitable as a direct plug-in replacement unit for FANUC A98L-0031-0012

On the production floor, this spare part is typically changed at the first low-battery alarm to prevent memory resets. Many maintenance teams keep one or more units in their MRO inventory for each active control, which shortens response time and helps avoid parameter reloads after planned shutdowns.

As a field replacement, the prewired harness allows a clean swap without crimping tools. Teams commonly perform the change while the CNC remains powered to maintain data continuity, then log the service date for the next preventive interval.

Each unit is verified on appropriate CNC test benches by skilled engineers, including open-circuit voltage checks and connector integrity inspection, then packed for industrial transit. Orders placed through Cnc-shopping USA on our US e-store are processed with professional packaging, and many stocked items ship directly from our Florida facility depending on availability. Standard warranty coverage applies in line with our spare-parts policy.

For urgent downtime events this item serves as an effective emergency spare to recover memory retention quickly. Cnc-shopping USA also supports sourcing of obsolete FANUC parts, and repair or exchange services may be available for related CNC modules to keep older installations operational.

Frequently asked questions about A98L-0031-0012 :

Is this a direct plug-in replacement for FANUC A98L-0031-0012?
Yes, it uses the correct SANYO CR17450SE-R 3 V cell with a prewired 2-pin JAE female connector for FANUC i-series backplanes. No rewiring is required for standard installations.

Which controls typically use this model?
It is commonly used on FANUC Series 16i, 18i and 21i as well as CNC i platforms mounted on the yellow backplane, including assemblies identified as A02B-0200-K102.

When should I replace it?
Replace at the first low-battery alarm shown on the operator panel. Maintenance teams usually perform the swap within a short window while keeping the control powered to avoid memory loss.

What are the physical dimensions and format?
The cell follows the 4/5A cylindrical format at about 45 x 18 mm, supplied as a ready-to-install harness with the correct 2-position connector.

Are there shipping considerations for lithium cells?
