This 3.6V 2600mAh Lithium thionyl chloride (Li-SOCl2) lithium thionyl chloride replacement backup battery is a form-fit-function substitute for the original memory-backup cell used in Siemens and other industrial control systems. It protects stored programs, RAM contents, and real-time clock data during power loss, and installs without rewiring, reprogramming, or controller reconfiguration.
It cross-references to 418-0042-00, NSN 6135-01-301-8776, NSN 6135-01-358-7471, 6630-U1, Siemens 6ES59800AE11, and Siemens 6ES79710BA00, plus additional cross-referenced part numbers. Match your existing battery by part number or by the equipment it powers to confirm fit. As a primary (non-rechargeable) lithium cell it offers long shelf life, low self-discharge, and a stable output voltage over extended standby periods. Replace on your equipment maker's recommended schedule and dispose of the spent cell per local regulations.
