Product Overview

The ABB 3HAC044075-001 is a 7.2 V lithium battery pack used to back up the serial measurement (revolution-counter) data in ABB robots. While the robot is powered off, this battery keeps the axis position memory alive so the robot remembers where each joint is.

When the battery runs low, the robot can lose its revolution counters and require an update or recalibration. Replacing the pack proactively — typically as part of scheduled maintenance — avoids unexpected calibration loss and downtime.
