The Allen Bradley 1763-BA Lithium Battery is a dedicated replacement battery for the MicroLogix 1100 PLC platform. It supports the controller's battery-dependent memory retention functions, helping preserve relevant stored information when the controller is not receiving external power.
The 1763-BA is commonly specified as a 3 V lithium battery with an 850 mAh capacity. Its wired connector assembly is designed to connect to the battery port inside a compatible MicroLogix 1100 controller. During replacement, the battery should be positioned in the designated compartment, with its wires routed and secured according to the controller's installation instructions.
Battery condition is an important part of PLC maintenance. When the controller's Battery Low indicator illuminates, checking the connector and replacing the battery when necessary can help prevent avoidable data-retention problems.
Lifecycle note: Rockwell Automation announced the discontinuation of the 1763-BA effective April 1, 2022. It is therefore important for maintenance and procurement teams to verify product authenticity, condition, and compatibility when sourcing this discontinued component.

Applications
The Allen Bradley 1763-BA Lithium Battery is a replacement battery designed for the MicroLogix 1100 programmable logic controller (PLC) system. It provides backup power for battery-dependent controller memory functions when the main power supply is interrupted.
Typical applications include:
PLC Memory Backup: Helps retain controller data during a loss of external power.
Industrial Machine Control: Supports MicroLogix 1100 controllers used in automated machinery.
Control Panel Maintenance: Provides a replacement option when the controller indicates a low battery condition.
Production Line Automation: Helps maintain stored control information during planned maintenance or power interruptions.
PLC Repair and Replacement: Suitable for maintenance work involving compatible MicroLogix 1100 controllers.
Key Features and Benefits
Designed for MicroLogix 1100: The 1763-BA is identified by Rockwell Automation as the replacement lithium battery for the Bulletin 1763 MicroLogix 1100 system.
Stable Backup Power: Its 3 V lithium battery design supports the controller's battery-dependent memory functions.
Wired Connector Design: The battery assembly uses connecting wires and a plug for installation in the controller's designated battery compartment.
Compact Construction: Its small form factor allows it to fit within the intended controller installation space.
Convenient Maintenance: Replacing a battery when the controller indicates a low-battery condition helps reduce the risk of losing retained information.
Technical FAQs
Q1: Which PLC system is compatible with the 1763-BA battery?
A: The 1763-BA is designed for the Allen Bradley MicroLogix 1100 programmable controller series.
Q2: What is the nominal voltage of the 1763-BA?
A: The battery has a nominal output voltage of 3 VDC.
Q3: What is its rated capacity?
A: The commonly specified capacity is 850 mAh. Confirm the rating against the battery manufacturer's documentation when evaluating an alternative battery.
Q4: Is the 1763-BA rechargeable?
A: No. It is a primary lithium battery and must not be recharged.
Q5: What does the Battery Low indicator mean on a MicroLogix 1100 controller?
A: The indicator means the battery may be disconnected or require replacement. The battery connector and battery condition should both be checked.
Q6: How soon should the battery be replaced after the low-battery indicator appears?
A: Rockwell Automation recommends replacing it immediately. The controller manual states that the controller is designed to operate for up to approximately two weeks after the indicator first turns on, but this should not be treated as a guaranteed retention period.
Q7: Can the PLC continue operating if the battery is disconnected?
A: The controller may continue operating with its external power supply, but battery-dependent memory retention during a power interruption may be affected.
Q8: Does replacing the battery require checking the connector polarity?
A: Yes. The replacement must be connected using the correct connector and orientation. Follow the controller's installation instructions rather than modifying the wiring.
Q9: What should be checked if the Battery Low indicator remains on after replacement?
A: Check that the battery connector is fully seated, the wiring is correctly routed, and the replacement battery is suitable and functional. If the warning remains, further controller inspection may be necessary.
Q10: Can another 3 V lithium battery replace the 1763-BA?
A: Not every 3 V battery is suitable. The replacement must match the required chemistry, capacity, physical dimensions, wiring, connector, and electrical characteristics.
