Industrial backup battery

The BatteryJack inc. BR-AGCF2W-old4 is a 6 V 1200 mAh lithium cell built for FANUC PLC backup power. It replaces the A98L-0031-0011#L reference and fits CNC machine tools, servers, programmers and measuring instruments. The cylindrical pack measures 17.5 mm in diameter and 33.5 mm in height. It weighs 13.5 g and ships as a single unit.

Suits legacy PLC maintenance teams

Maintenance engineers who need a direct drop-in for the FANUC part number will find the voltage, capacity and form factor match the original specification. The wide operating window from -55 to +85 degrees C covers harsh shop-floor environments. Buyers who require a rechargeable pack, a different voltage or a multi-cell assembly should look elsewhere.

1200 mAh at 6 V

The rated capacity delivers reliable backup for real-time clocks, memory retention and low-draw instrumentation. Low self-discharge preserves charge during long idle periods. High-density chemistry keeps the footprint small. The cell is not designed for high-current cycling or as a primary power source for motors or displays.

Questions about this item

What FANUC PLC part number must the BR-AGCF2W-old4 replace for it to work?

The battery is built for the A98L-0031-0011#L FANUC PLC, so that exact part number must be the one you are replacing.

Will the 6 V 1200 mAh lithium cell fit in equipment designed for the older 996 reference?

Yes, the BR-AGCF2W-old4 matches the 996 reference and delivers the same 6 V 1200 mAh rating in a 17.5 mm by 33.5 mm package.

How can I confirm the battery is holding its charge after installation?

Measure the terminal voltage; a healthy cell reads near 6 V and the low self-discharge rate means it should stay close to that value over weeks of standby.
