- Provides controller-memory backup for Series A 1756-L6x ControlLogix 5560 controllers
- Reports a low-battery condition through the controller BAT indicator and a documented minor fault
- Uses a temperature-based replacement schedule for higher-temperature installations
Allen-Bradley 1756-BA1 is a hermetically sealed, non-rechargeable lithium battery assembly for controller-memory backup.
Rockwell specifies it for Series A 1756-L6x controllers and documents its use with selected earlier ControlLogix, FlexLogix, and DriveLogix controllers. Series B 1756-L6x controllers use the different 1756-BA2 battery.
Before replacement, confirm the controller catalog number and series, inspect the connector, apply hazardous-location precautions, record the installation date, and follow the temperature-based maintenance schedule.
Availability, condition, price, and shipping time for Allen-Bradley 1756-BA1 are confirmed during quotation.
