Compatible Siemens Industrial Controllers
Siemens identifies the original 6FC5247-0AA18-0AA0 battery as a spare part for selected SINUMERIK and SIMOTION hardware.
Applications include supported:
- SINUMERIK CNC systems
- SINUMERIK 808D controllers
- MMC and NCU assemblies
- CCU and MCI boards
- SIMOTION D4x5-X equipment
However, different hardware versions may use different backup batteries and connection arrangements.
Therefore, verify the exact equipment model and original battery reference before purchasing.
Why Is a CNC Backup Battery Important?
Certain CNC controllers use lithium batteries to retain designated information during power interruptions.
For example, the supported equipment may require battery power to maintain stored control data.
Additionally, scheduled battery maintenance can reduce the risk of unexpected backup-power failure.
Nevertheless, actual retention behaviour depends on controller hardware, configuration and battery condition.

575332TA and 6FC5247-0AA18-0AA0 Compatibility
The 575332TA reference appears in aftermarket battery catalogues as an alternative reference for 6FC5247-0AA18-0AA0.
However, battery assemblies with these references can differ in connector configuration, wire length and polarity.
Consequently, a matching part-number description alone does not guarantee compatibility.
Always compare the replacement assembly with the original battery installed in your equipment.
Connector and Polarity Requirements
The pictured assembly uses red-and-black connecting wires and a plug connector.
Before installation, verify the physical connector type and positive and negative terminal positions.
Even if two connectors appear similar, their internal wiring may differ.
Incorrect polarity can damage equipment or prevent the backup function from operating correctly.
Battery Installation and Replacement
- Identify the full SINUMERIK or SIMOTION equipment model.
- Confirm the original battery reference.
- Review the manufacturer’s documented replacement procedure.
- Protect retained controller data according to the equipment instructions.
- Verify the new battery’s voltage, chemistry and physical condition.
- Check connector shape and polarity.
- Install the replacement using the correct maintenance procedure.
- Verify the controller’s battery-status indication.
Important: Siemens documents specific battery replacement precautions for SINUMERIK systems. Incorrect replacement may cause loss of retained data. Qualified maintenance personnel should follow the relevant equipment manual.
Battery Storage and Handling
Store unused lithium backup batteries in a suitable cool, dry location.
Furthermore, protect the connector contacts from accidental short circuits.
Inspect the wires, connector and battery wrapping before installation.
Do not use damaged, leaking or visibly deteriorated batteries.
Important Battery Safety Instructions
- Never recharge this primary lithium battery.
- Do not short-circuit the connector contacts.
- Do not crush, puncture or dismantle the cell.
- Keep away from excessive heat and fire.
- Do not reverse connector polarity.
- Do not install damaged or leaking batteries.
- Keep batteries away from children.
- Follow applicable battery disposal and recycling requirements.
