ReplacementBatteryfortheABBIRB4400-7.2V3600mAhLithium

This 7.2V 3600mAh lithium thionyl chloride (Li-SOCl2) battery is a direct replacement memory-backup cell for the ABB IRB 4400 robot controller. The ABB IRB 4400 is a compact six-axis industrial robot used for machine tending, material handling, and process applications with payloads up to 60 kg. It is built as a form-fit-function replacement for the original backup battery, so it installs without rewiring, reprogramming, or controller reconfiguration, and protects stored programs, RAM, and real-time clock data during power loss.

This battery cross-references to ABB 3HAC020536-003, 3HAC020536-005, 3HAC020536-006, 3HAC020536-007, 3HAC020536-011, and 3HAC020536-012, plus 34 additional cross-referenced part numbers. Match your existing OEM battery by part number or by the equipment it powers to confirm fit. In ABB robot systems this cell backs up the serial measurement board (SMB) revolution counter data, so replacing it in time avoids re-calibrating the robot axes. Lithium thionyl chloride primary cells deliver high energy density and a very low self-discharge rate, holding a stable 7.2V nominal output over long standby periods, which suits low-drain memory-backup duty.
