Replacement Battery for the Mitsubishi 2CR17335AWK17 - 6V 1800mAh Lithium

Protect stored programs, RAM, and real-time clock data on Mitsubishi PLC and industrial control equipment with this 6V 1800mAh lithium manganese dioxide (Li-MnO₂) 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 2CR17335AWK17, 80466-ZW2222-2, Mitsubishi MR-BAT6V1, and Mitsubishi MR-BAT6V1SET, 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. As a lithium manganese dioxide (CR) primary cell, it combines a long shelf life with low self-discharge and a flat 6V discharge curve, making it well suited to program and clock retention. It is non-rechargeable and should be swapped out when depleted.
