Replacement Battery for the ABB 3HAC044500-001 - 7.2V 3600mAh Lithium

Protect stored programs, RAM, and real-time clock data on ABB PLC and industrial control equipment with this 7.2V 3600mAh lithium thionyl chloride (Li-SOCl₂) direct-replacement backup battery. It is built as a form-fit-function replacement for the original memory-backup cell, so it installs without rewiring, reprogramming, or controller reconfiguration.

This battery cross-references to ABB 3HAC020536-003, ABB 3HAC020536-005, ABB 3HAC020536-006, ABB 3HAC020536-007, ABB 3HAC020536-011, and ABB 3HAC020536-012, plus 34 additional cross-referenced part numbers, giving you a single verified replacement across these part numbers. Match your existing OEM battery by part number or by the equipment it powers to confirm fit. Lithium thionyl chloride cells deliver a high energy density and an exceptionally low self-discharge rate, holding a stable 7.2V nominal output over long standby periods—ideal for the low-drain memory-backup duty this battery is built for. It is a primary (non-rechargeable) cell and should be replaced rather than recharged once depleted.
