Replacement Battery for the Bosch Rexroth (Indramat) R911277133 - 3.6V 1000mAh Lithium

Protect stored programs, RAM, and real-time clock data on Indramat, Interstate, Saft, Bosch Rexroth (Indramat), and other industrial control systems with this 3.6V 1000mAh 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 Indramat 257101, Interstate ALIT0192, Saft LS14250-RR, and Bosch Rexroth (Indramat) R911277133, 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.
