GE FANUC 44A724534-001 Lithium Battery Module

The GE FANUC 44A724534-001, also cataloged as the 44A724534-001 Lithium Battery Module, operates as a dedicated hardware component for memory backup and real-time clock retention within GE FANUC PLC and controller platforms. Hardware Specifications Parameter Specification Model 44A724534-001 Brand GE FANUC Origin Japan Weight 0.04 lbs (0.018 kg) Dimensions 0.67 in x 1.30 in (17 mm x 33 mm) Operating Temp -40 to +85 deg C Power Consumption Non-rechargeable primary battery Battery Chemistry Lithium Carbon Monofluoride ($Li-CF_n$) / Panasonic BR2/3A cell Nominal Voltage 3.0 VDC Nominal Capacity 1200 mAh Connection Type Insulated wire leads with polarized connector Deterministic Backplane & Power Retention The battery connects directly to the CPU power management circuit to maintain volatile RAM system memory during primary backplane bus power interruption. Channel circuitry minimizes internal discharge, ensuring continuous firmware flash synchronization and real-time clock stability across GE FANUC controller racks. Integrated protective diode isolation prevents reverse charging currents from feeding into the battery when the main backplane power supply is fully energized. Frequently Asked Questions Q: Is it safe to swap the 44A724534-001 battery while the host PLC rack is running? A: Yes. Replacing the backup battery while the PLC backplane power supply remains turned on prevents data loss from volatile RAM during the replacement procedure. Q: What indicates that the 3.0 VDC backup battery needs replacement? A: The main controller monitors backup cell terminal voltage and illuminates a designated low-battery diagnostic indicator (BATT LED) on the module front panel when voltage drops below operational limits. Field Installation Guidelines Connector Alignment: Check the polarized harness connector for correct keying orientation prior to plugging into the CPU battery receptacle. Short-Circuit Prevention: Keep wire lead terminals insulated during handling. Accidental contact between open leads can cause rapid discharge or internal cell damage. Mechanical Securing: Place the shrink-wrapped battery body securely into its designated retaining clip inside the module housing to prevent movement caused by machine vibration. Environmental Safety: Do not recharge, crush, dismantle, or expose the lithium battery to temperatures above 85 deg C. Dispose of depleted cells according to industrial lithium battery disposal regulations.
