ReplacementBatteryfortheABBIRB1520-7.2V3600mAhLithium

This 7.2V 3600mAh lithium replacement battery is a direct, form-fit-function substitute for the memory-backup battery sold under part number ABB IRB 1520. It protects stored programs, RAM contents, and real-time clock data during power loss, and installs without rewiring, reprogramming, or controller reconfiguration.

It is most commonly used as the serial measurement board (SMB) backup battery on ABB IRB series industrial robot manipulators, where it retains the robot's absolute revolution counter data when controller power is removed. It also serves ABB PLC and industrial control equipment that specifies a 7.2 V pack in the 3HAC020536 battery family.

This battery cross-references to ABB 3HAC020536-003, 3HAC020536-005, 3HAC020536-006, 3HAC020536-007, 3HAC020536-011, and 3HAC020536-012, plus more than 30 additional part numbers, among other part numbers in the same family. Match your existing battery by part number or by the equipment it powers to confirm fit. Lithium thionyl chloride cells deliver high energy density, very low self-discharge, and a long shelf life. It is a primary (non-rechargeable) cell and should be replaced, not recharged, at end of life.
