Industrial PLC Backup Battery

The BatteryJack BR-AGCF2W-old1 is a 6V 1200mAh primary cell built for programmable-logic controllers, CNC equipment and industrial instrumentation. It delivers reliable backup power for real-time clocks and memory retention in harsh factory environments.

6 Volt 1200 mAh Rating

The single decisive specification is the 6V 1200mAh capacity, which must match the original A98L-0031-0011#L requirement exactly; a different voltage or capacity will not sustain the controller during mains loss.

Wide Temperature Low Self-Discharge

Rated for continuous operation from -55 to +85 degrees C, the cell maintains charge with minimal self-discharge across extreme thermal cycles. Its high-density chemistry ensures stable voltage without active cooling or maintenance.

Questions about this item

How long will the 1200 mAh capacity keep a PLC memory backup running?

The 1200 mAh rating at 6 V supplies the listed current for one hour; actual backup time depends on the PLC's quiescent draw, which is typically in the microampere range, so the cell can last years in a real machine.

What voltage and chemistry does the BR-AGCF2W-old1 use, and what does that limit?

It is a 6 V primary lithium cell, so it cannot be recharged and its voltage stays near 6 V until depletion, limiting it to backup or low-drain roles rather than cyclic power.

Will the 17.5 mm diameter and 33.5 mm height fit the battery holder on my CNC controller?

The cell measures 17.5 mm in diameter and 33.5 mm in height, matching the standard 1/2 AA form factor used in many PLC and CNC battery compartments.
