ABB 3HAC044075-001 Lithium Battery Unit 7.2V for IRC5 SMB

Lithium Battery Unit for ABB IRC5 SMB Memory Backup

Specifications

Industrial Applications

• ABB IRC5 controller SMB / system memory backup — retains program, calibration and axis-position data during power loss.
• Automotive body welding, paint shop and final-assembly lines.
• Electronics and semiconductor pick-and-place and handling cells.
• Metal fabrication, palletizing and general industrial robotics.
• Preventive maintenance (scheduled ~5-year battery replacement).
• Emergency service and IRC5 controller repair / SMB module servicing.

Design Purpose

This battery unit provides non-volatile backup power to the IRC5 SMB so that CPU program code, calibration data and axis positions are retained during power loss or controller shutdown. It prevents loss of robot joint-position data and the re-calibration downtime that follows, with a service life that matches ABB's recommended maintenance interval.

Common Failure Modes

• Capacity fade / end-of-life causing memory loss on power cycle (typically after ~5 years).
• Leakage or terminal corrosion from age or elevated temperature.
• Swelling or physical damage from mishandling.
• Wrong variant installed — poor seating or SMB not backed up.
• Improper disposal or short-circuit hazard from mishandling.
