Replacement Battery for the Mitsubishi MR-BAT6V1 - 6V 1650mAh Lithium

Protect stored programs, RAM, and real-time clock data on Mitsubishi PLC and industrial control equipment with this 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 Mitsubishi 2CR17335A WK17, Mitsubishi MR-J4, Mitsubishi MR-BAT6V1SET, and Mitsubishi MR-BAT6V1, 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 6V output, so stored programs and settings stay protected during power loss. It is non-rechargeable and should be replaced rather than recharged.
