Information About 1756-BA2

The 1756-BA2 is part of the ControlLogix Series B controller accessories and is engineered to maintain non-volatile memory and clock functions when the processor is powered down. It uses a lithium cell connected via wire-lead termination and installs directly into the chassis for secure integration. With a nominal 3 VDC output and approximately 1200 mAh capacity, the battery provides multi-year backup life under recommended operating temperatures. Typical use is within 1756-L6x processor modules where continuous memory retention is required for automation tasks, sequencing, and controller configuration.

Key Features:

  • Lithium Metal Battery Assembly: Provides non-volatile memory backup for ControlLogix processors.
  • Compatible with 1756-L6x Series B: Designed for direct use with ControlLogix controllers.
  • 3 VDC Output: Ensures stable retention voltage for memory and clock operations.
  • Wire-Lead Termination: Offers secure and simple connection to the processor module.
  • Multi-Year Service Life: Rated for long duration when used within recommended temperature limits.
  • Open-Style Installation: Fits horizontally within the chassis environment.

The 1756-BA2 delivers the reliability and precision required for secure memory retention in industrial ControlLogix systems.

Frequently Asked Questions about 1756-BA2
Question: How long does the 1756-BA2 battery last?
Date Update:17/06/2025
Answer:

The typical lifespan of the 1756-BA2 lithium battery is a minimum of 3 years under standard conditions. This estimate assumes continuous operation within an ambient temperature range of 0 to 35°C. As the temperature rises beyond this range, the battery’s life expectancy gradually decreases. Factors such as storage environment, frequency of usage, and humidity can also impact battery performance. It is recommended to monitor the system’s battery status and replace the unit promptly when the controller indicates a low battery condition.

Question: What are the recommended installation steps?
Date Update:17/06/2025
Answer:
  • Power down the ControlLogix controller.
  • Locate the battery connector on the chassis.
  • Disconnect the old battery, ensuring safe handling and disposal.
  • Connect the wire leads of the 1756-BA2 to the designated port.
  • Secure the battery properly and restart the system.
  • Verify battery recognition in the controller’s diagnostic interface.

Proper installation prevents data loss and supports safe operation.

Question: How does temperature affect the battery's lifespan?
Date Update:17/06/2025
Answer:

The operating environment significantly influences the 1756-BA2 battery’s longevity. When used within the optimal temperature range of 0 to 35°C, it can reliably last for up to 3 years. Higher temperatures accelerate internal chemical reactions, reducing the battery’s usable life. Likewise, extremely low temperatures can diminish performance temporarily. Therefore, maintaining a stable environment not only preserves battery life but also ensures consistent system reliability.

Question: Can the 1756-BA2 be recharged or reused?
Date Update:17/06/2025
Answer:

No, the 1756-BA2 is a non-rechargeable primary lithium battery and should not be recharged under any circumstances. Attempting to recharge it can lead to fire, explosion, or system damage. Once depleted or after reaching its service life, the battery must be replaced. It’s also important not to open, puncture, or incinerate the battery. Always dispose of it following local environmental regulations and company safety policies.

Question: Is the 1756-BA2 still in production?
Date Update:17/06/2025
Answer:

Yes, the Allen-Bradley 1756-BA2 is currently in production and is classified with a lifecycle status of "Active Mature". This means that while it is still available for use in existing systems, Rockwell Automation may eventually phase it out as newer battery models and controller hardware are introduced.
