The IC200ACC403 provides essential memory backup for GE VersaMax Micro PLC systems, specifically targeting the 23-point and 28-point controllers. This 3.0V Lithium coil cell assembly features pre-installed wire leads and a specialized connector to ensure a secure interface with the PLC’s internal battery holder. It maintains critical RAM data and real-time clock (RTC) settings during power interruptions. We supply this unit as 100% Brand New and Original, ensuring your automation logic remains intact during scheduled maintenance or unexpected power loss.

Guaranteed Data Integrity: The IC200ACC403 preserves the user program, register data, and internal state variables. This eliminates the need for manual program reloads and minimizes downtime following a facility power cycle.
Intelligent Status Monitoring: The VersaMax CPU actively monitors the battery health. It reports low-voltage conditions directly to the PLC fault table and triggers internal status bits (%SA011/%SA014). This allow engineers to program HMI alarms for proactive battery replacement before data loss occurs.
Optimized for High-Temperature Environments: Unlike standard consumer batteries, this industrial-grade lithium cell maintains a reliable discharge curve even in hot control cabinets. It provides a minimum of 4 months of continuous backup at 55°C, ensuring protection during long-term machine storage.
Plug-and-Play Maintenance: The integrated wire leads and connector allow for rapid replacement without specialized soldering tools. The design ensures the correct polarity, preventing potential circuit damage during field installation.
Long-Term Storage Stability: With a shelf life of up to 5 years, the IC200ACC403 serves as an ideal spare part to keep in inventory. The low self-discharge rate guarantees that the battery remains ready for deployment whenever the system requires a fresh cell.
Can I use a standard CR2032 from a retail store instead of the IC200ACC403?
While the cell itself is a 3V lithium type, the IC200ACC403 includes the specific wire leads and connector required by the VersaMax Micro housing. Standard batteries lack these leads and will not interface with the PLC's internal circuitry.
How often should I replace the IC200ACC403?
GE Fanuc recommends monitoring the CPU status bits. However, as a best practice, most maintenance teams replace the battery every 2 to 3 years to ensure the 4-month backup window remains valid, especially in environments with frequent power-down cycles.
Does the PLC lose its program immediately when I unplug the old battery?
The PLC typically uses an onboard capacitor to maintain memory for a very short duration (seconds to minutes) while you swap the battery. To prevent data loss, always perform the battery replacement while the PLC remains powered on, following all electrical safety protocols.
What happens if the battery fails and I don't replace it?
If the battery voltage drops below the threshold and the PLC loses main power, the volatile RAM will clear. This results in the loss of all user-defined variables and the application program unless it was previously saved to non-volatile flash memory.
