Replacement Battery for the Siemens TP270 - 3.6V 1650mAh Lithium

Protect stored programs, RAM, and real-time clock data on Siemens, Fedco, Interstate, Sonnenschein, and other industrial control systems with this 3.6V 1650mAh lithium 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 Siemens 40006540, Siemens 40007022, BTP-82M, Fedco TL5955-SS, Interstate LIT6093, and Siemens OP15, plus 21 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. This primary lithium cell offers a long shelf life, low self-discharge, and a stable 3.6V output, so stored programs and settings stay protected during power loss. It is non-rechargeable and should be replaced rather than recharged.
