Description
This 3V 550mAh lithium manganese dioxide (Li-MnO2) battery is a direct replacement memory-backup cell for the ABB TA521 battery for the AC500 PLC. The TA521 is the battery accessory for ABB AC500 CPUs; the cell maintains SRAM data and the real-time clock when the PLC is powered down. 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 1SAP180300R0001, SAP180300R0001, 4016779648950, CR2450-WC, and the ABB AC500 PLC family, plus 4 additional cross-referenced part numbers. Match your existing OEM battery by part number or by the equipment it powers to confirm fit. Lithium manganese dioxide primary cells deliver high energy density and a very low self-discharge rate, holding a stable 3V nominal output over long standby periods, which suits low-drain memory-backup duty.
