Industrial PLC Backup Battery

The DUSLAN 6V 2400mAh lithium cell replaces the Panasonic BR-2/3AGCT4A buffer battery used in Fanuc 18-T series programmable logic controllers, robot controllers and ALPHA iSV, BETA iSV and BETA iSVSP CNC amplifiers. It supplies the 6 volt backup voltage that preserves ladder logic, parameters and encoder position when main power is removed.

Installation Requirements

The pack measures 1.80 by 1.38 by 1.33 inches and terminates in wire leads with a connector that plugs directly into the controller board, so no soldering or adapter cables are required. It fits the existing battery compartment in the listed Fanuc A06B-6114-K504 and CL 25A units, freeing the maintenance technician from fabricating custom mounts or wiring harnesses.

Thermal and Power Profile

Lithium chemistry delivers stable output across an operational range of -40 to +85 Celsius, allowing the battery to remain reliable inside cabinets that see wide temperature swings. Self-discharge is low enough to support multi-year backup intervals, and the cell draws no load current while the controller is powered, so it adds no measurable heat or noise to the enclosure.

Questions about this item

How long will the 2400 mAh capacity last before the buffer memory in a Fanuc 18-T controller loses data?

The 2400 mAh lithium cell is rated to maintain the 79499 buffer for the controller's specified backup interval, typically several years under normal power-off conditions.

Does the battery generate noticeable heat when installed inside a Fanuc ALPHA iSV amplifier running continuously?

Lithium primary chemistry produces negligible self-heating; the cell stays within the -40 °C to +85 °C operating range without active cooling in the amplifier enclosure.

Which Fanuc controller models accept the wire-lead connector on this A98L-0031-0025 battery without an adapter?

Direct fit includes Fanuc 18-T series PLCs, robot controllers and ALPHA iSV, BETA iSV, BETA iSVSP CNC amplifiers listed in the compatibility table.
