Component Role Explained
The 1769-BA is a lithium battery backup power supply specifically designed for certain CompactLogix controllers and Compact I/O systems. Its primary function is to protect user program data and controller memory during power outages or system shutdowns, ensuring the device resumes operation immediately upon power restoration without requiring reloading or reconfiguring the control program.
This battery must be installed directly within the controller or a designated battery compartment. It is a serviceable maintenance part, not a permanent system component.
