This 3.6V 2100mAh lithium replacement battery is a direct substitute for the Mitsubishi MR-BAT memory backup battery used in MELSERVO servo amplifiers, where it retains absolute position encoder data. 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 Eternacell, Mitsubishi, Interstate, Maxell, and other industrial control systems with this 3.6V 2100mAh 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 Eternacell B9670MC, Mitsubishi A6BAT-MRBAT, Mitsubishi C52012, Interstate LIT5085, Maxell ER17/33WKP, and Mitsubishi A Series, plus 9 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.
