Allen Bradley 1763-BA PLC Replacement Battery | MicroLogix 1100

Product Overview

The Allen Bradley 1763-BA serves as the primary power backup solution for the MicroLogix 1100 controller series. This high-energy lithium cell preserves the controller's user program and data table during power outages, preventing costly logic loss and system re-initialization. We supply this component as 100% Brand New and Factory Original, ensuring your automation system maintains its volatile memory integrity with maximum shelf life and discharge stability.

Technical Specifications

The 1763-BA utilizes a specialized lithium chemistry to provide long-term voltage stability for CMOS RAM backup:

Engineering Advantages

• Reliable Data Retention: This battery provides the specific 3V current required to maintain the MicroLogix 1100 CMOS RAM. It prevents the CPU from reverting to factory defaults or losing critical process setpoints during scheduled shutdowns or unexpected grid failure.

• High Energy Density: The 850mAh lithium chemistry offers a superior capacity-to-size ratio. This allows the battery to fit into the compact internal compartment of the MicroLogix 1100 while providing years of standby protection.

• Extreme Temperature Stability: The industrial lithium construction resists electrolyte degradation across wide temperature swings. This ensures the battery functions reliably even in non-climate-controlled control cabinets where temperatures often fluctuate.

• Leak-Resistant Design: The 1763-BA features a hermetically sealed casing. This design protects the sensitive PLC circuit board from corrosive electrolyte leakage, a common failure point in lower-quality consumer-grade batteries.

FAQs

• Is the 1763-BA battery I receive 100% Brand New?

  Yes. We guarantee that every 1763-BA ships as 100% Brand New stock with a fresh date code. We do not stock used or refurbished batteries, ensuring you receive the full 850mAh capacity and maximum operational life.

• How often should I replace the battery in my MicroLogix 1100?

  Standard industrial maintenance protocols suggest replacing the 1763-BA every 2 to 3 years. While the lithium cell has a long shelf life, active backup cycles and high ambient temperatures can deplete the capacity faster. Always replace the battery immediately if the "BATT" LED on the controller faceplate turns red.

• Will I lose my program if I remove the battery while the PLC is off?

  Yes. If you remove the battery while the PLC lacks backplane power, the volatile memory will clear within minutes. To prevent program loss, replace the battery while the MicroLogix 1100 remains powered on (exercise extreme caution around live terminals) or ensure you have a current project backup in RSLogix 500.

• Is this battery rechargeable?

  No. Despite some documentation errors in third-party databases, the 1763-BA is a Primary Lithium cell and is NOT rechargeable. Attempting to charge this battery creates a significant fire and explosion hazard within the PLC housing.
