Selection Guide
Use the following decision tree to select the correct SMB battery unit:
- Identify your controller revision: Check the label inside the IRC5 cabinet door for the main computer board revision (e.g., DSQC 639, DSQC 1000).
- Check current part number: The installed battery unit’s label will show the ABB part number. Match it to the table above.
- Confirm robot software version: RobotWare 5.x → use 3HAC029924-003 or 3HAC042285-001. RobotWare 6.x / 7.x → use 3HAC044168-001 or 3HEA800439-002.
- Replacement interval: ABB recommends replacing the SMB battery every 36 months under standard operating conditions.

Replacement & Compatibility FAQ
Q: Can I use 3HAC042285-001 instead of 3HAC044168-001?
A: In most IRC5 installations, yes — they share the same form, fit, and function. Confirm your RobotWare version first.
Q: What happens if the SMB battery dies?
A: The robot will lose axis position memory and require a full calibration (revolution counter update) before it can operate safely.
Q: Is 3HEA800439-002 a drop-in replacement?
A: It includes an integrated IO board. It is compatible with IRC5 systems that use the combined SMB IO assembly. Check your wiring harness connector before substituting.
Q: How do I know when to replace the battery?
A: ABB FlexPendant will display a “38213 Battery charge low” or “38214 Battery voltage low” system event. Replace immediately to avoid data loss.
Q: Do you provide a warranty?
A: Yes — all genuine OEM parts carry a 12-month warranty against manufacturing defects from date of shipment.
