Compatible Allen-Bradley PLC Controllers
Rockwell Automation identifies the 1756-BA1 battery for selected ControlLogix Series A controllers.
These include:
- 1756-L61 Series A
- 1756-L62 Series A
- 1756-L63 Series A
The manufacturer also lists 1756-BA1 for certain older ControlLogix controller references. However, compatibility depends on the exact controller catalogue number and series.
Therefore, confirm the complete controller model before purchasing.
Why Do ControlLogix Controllers Need Backup Batteries?
Certain ControlLogix controllers use lithium backup batteries to retain designated memory contents when the normal power supply is unavailable.
For example, a supported controller may rely on the battery to preserve battery-backed information during a power interruption.
Furthermore, appropriate battery maintenance helps reduce the risk of unexpected memory loss.
Nevertheless, exact retention behaviour depends on the controller model, memory configuration and battery condition.
Allen-Bradley 1756-BA1 vs 1756-BA2
Although both batteries are associated with ControlLogix controllers, they are not interchangeable by default.
1756-BA1
- For specified Series A ControlLogix controllers
- Primary lithium battery
- Manufacturer part number: 1756-BA1
1756-BA2
- For specified Series B ControlLogix controllers
- Different battery assembly reference
- Manufacturer part number: 1756-BA2
Consequently, always verify the controller series before selecting a replacement.
Using an incorrect battery may cause equipment problems or damage.
