Purchase now: Allen-Bradley 1763-BA MicroLogix 1100 Lithium Battery
Atlantechdrives provides you the 1763-BA, the official lithium replacement battery designed specifically for the MicroLogix 1100 controller series. This high-energy density battery is a critical maintenance component, ensuring the retention of the controller’s user program, retentive data, and the Real-Time Clock (RTC) settings during power-down periods.
- Battery Type: Lithium (Li-SOCl2)
- Compatibility: All MicroLogix 1100 (1763) Series
- Function: Program and RTC Data Retention
- Service Life: Approximately 5 years (under normal conditions)
- Installation: Plug-and-play connector for easy replacement
Technical Importance: Safeguarding Your Logic Integrity
The 1763-BA is engineered to provide a stable 3.0V DC potential to the MicroLogix 1100 logic board when primary input power is lost. While the MicroLogix 1100 features non-volatile flash memory for long-term program backup, the 1763-BA is indispensable for maintaining «Retentive» data—such as counter values, timer accumulations, and recipes—that change during machine operation. Without a functional battery, a power cycle can reset your machine’s cycle counts or position data, leading to synchronization issues and production delays. Furthermore, the Real-Time Clock relies exclusively on the 1763-BA; without it, any time-stamped diagnostic logs or scheduled events within your RSLogix 500 program will be invalidated upon restart.
Expert Tips: Preventive Replacement Strategy
We recommend a strict preventive maintenance schedule for the 1763-BA. Do not wait for the «BATT» LED on the controller faceplate to turn red. Once that LED illuminates, you typically have only a few days (or hours, depending on ambient temperature) to replace it before data loss occurs. A best practice is to replace the 1763-BA every 3 years in high-vibration or high-temperature environments. When performing the swap, always keep the PLC powered up (if safe to do so) to ensure no data is lost during the few seconds the battery is disconnected. If the PLC must be off, ensure you have a current backup of the project file on your PC before removing the old cell.
Maintenance and Storage Guidelines
The 1763-BA has a shelf life of up to 10 years if stored in a cool, dry environment. However, once installed, industrial heat can accelerate the chemical depletion of the lithium cell. Periodically check the diagnostic bits in the controller’s Status File (S:5/11) which tracks the low-battery condition. Sourcing your 1763-BA from Atlantechdrives ensures you receive a fresh, high-quality lithium cell that meets all original Allen-Bradley voltage and discharge curve specifications, protecting your automation investment from accidental resets.
FAQs
Q: Can I use a standard off-the-shelf lithium battery?
A: No. The 1763-BA features a specific wire-lead connector and polarity designed for the 1763 chassis. Using an incorrect battery can damage the logic board.
Q: Does the MicroLogix 1100 lose its program immediately without a battery?
A: No, the program is saved in Flash, but all dynamic data and the clock will reset to zero.
