Information About 1756-BA2

The 1756-BA2 ControlLogix Lithium Metal Battery Assembly by Allen-Bradley is a battery assembly for the Allen-Bradley 1756-L6x Controller Series B which is used to back up the controller’s stored information in the non-volatile memory and it keeps the controller’s internal clock working when the controller is powered down. The battery assembly consists of a Duracell Lithium Battery Cell which is installed on the chassis and the battery functions and lifespan depend on the environmental conditions around the chassis and the frequency of use. The 1756-BA2 has an electrical rating of 3V DC supply voltage with a maximum battery capacity of 1200mAh and it employs a (Wire Leads to Connector) Termination type. It has a minimum lifespan of 3 years when used at 0 to 35 °C (0 to 95 °F), but will gradually de-rate at any temperature above this range. The 1756-BA2 is stored at a recommended temperature of 25 °C (77 °F) at 40-60% non-condensing relative humidity, but can be stored at a range of range between -45° and 85° C around when the storage time duration is less than 30 days, and the storage temperature must not exceed 85  0C.

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.
