This 3.6V 2600mAh lithium replacement battery is a direct substitute for the Mitsubishi CR3 memory backup battery used in Mitsubishi PLC, CNC, servo, and HMI equipment. When the original cell weakens, stored programs, parameters, and clock data are at risk during a power outage; replacing the battery on schedule keeps that data intact.
Protect stored programs, RAM, and real-time clock data on Maxell, Mitsubishi, Saft, 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 Maxell ER6VCT, Maxell ER6-WK11, Mitsubishi A11BU0060B, Mitsubishi BKO-NC2157H01, Mitsubishi CR1, and Mitsubishi CR2, plus 8 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.
