Replacement Battery for the Saft LS14500BA - 3.6V 2600mAh Lithium

Protect stored programs, RAM, and real-time clock data on NSN, Siemens, EaglePicher, Toshiba, and other industrial control systems with this 3.6V 2600mAh 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 418-0042-00, NSN 6135-01-301-8776, NSN 6135-01-358-7471, 6630-U1, Siemens 6ES59800AE11, and Siemens 6ES79710BA00, plus 14 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 3.6V 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.
