The Allen-Bradley 1769-BA functions as a premium Lithium Thionyl Chloride ($Li-SOCl_2$) battery assembly engineered by Rockwell Automation. It provides critical primary backup power to the volatile memory (RAM) and internal Real-Time Clock (RTC) across legacy Allen-Bradley CompactLogix and MicroLogix controller hardware. If the primary power supply drops out, an unmaintained or depleted battery cell causes the immediate erasure of the controller's active project file, configuration parameters, and variable tag tables.
The cell features a dedicated, factory-attached wire lead and a specialized 2-pin keyed connector plug. This configuration ensures a solid, polarized link directly onto the central processing unit motherboard. While modern 5370 controllers rely on capacitor modules, the 1769-BA cell remains a mandatory maintenance component to maintain process uptime and data protection across established 1769-L2x and L3x industrial layouts.
We deliver this item exclusively as 100% brand new, original, and factory-sealed to ensure maximum chemical charge level, peak capacity, and complete data safety for your running control software.
