Frequently Asked Questions about 1756-BATM
Question: What is the 1756-BATM module?
Date Update:17/06/2025
Answer:

The 1756-BATM is a battery backup module used in Allen-Bradley ControlLogix systems. It provides backup power for ControlLogix controllers during a loss of chassis power. Its primary function is to retain volatile memory and enable safe shutdown procedures. The module is mounted directly into the ControlLogix chassis and operates independently of controller logic. It includes a replaceable battery cartridge (1756-BATA) that maintains power for several hours. This helps prevent data loss in critical automation systems.

Question: How long does the battery last?
Date Update:17/06/2025
Answer:

The internal battery (1756-BATA) typically lasts 3 to 5 years under normal environmental conditions. Runtime during power loss depends on the load and temperature but generally allows at least 30 minutes to several hours of backup. A status LED indicates when the battery needs replacement. Periodic testing and scheduled replacement ensure system reliability. Replacement can be done without removing the entire module. Batteries should always be replaced with certified Allen-Bradley units.

Question: What does the status LED indicate?
Date Update:17/06/2025
Answer:

The module features a single status LED that communicates the health of the battery. A solid green LED indicates normal operation, while red or flashing lights signal a low battery or fault. This enables quick diagnostics during inspections. The LED is visible from the front panel for easy status checks. When a low battery is detected, the user should schedule prompt replacement. Detailed status can also be accessed via the controller interface.

Question: Is the 1756-BATM still available?
Date Update:17/06/2025
Answer:

No, the Allen-Bradley 1756-BATM has been discontinued since July 18, 2017, and is no longer available for sale from Rockwell Automation. There is currently no planned official replacement listed by the manufacturer. Customers are advised to remove this part from new designs and avoid referencing it in future projects. Existing systems may continue to use the module if operational, but sourcing spare parts may be limited to surplus markets. Users are encouraged to explore modern ControlLogix architectures that use controllers with built-in non-volatile memory. Consulting system integrators for retrofit options is also recommended.

Question: What is the battery model used?
Date Update:17/06/2025
Answer:

The 1756-BATM uses a replaceable battery cartridge called the 1756-BATA. This battery unit can be removed and replaced without uninstalling the entire module. It is designed to meet industrial backup standards with high capacity and long life. The 1756-BATA is available separately through Rockwell Automation or authorized distributors. Only official batteries should be used to ensure safe operation. Improper substitutions may void warranties or lead to malfunction.
