{"product_id":"replacement-battery-mitsubishi-mr-j2-comp-153","title":"Replacement Battery for the Mitsubishi MR-J2 - 3.6V 2100mAh Lithium","description":"\u003cp\u003eThis 3.6V 2100mAh lithium replacement battery is a direct substitute for the Mitsubishi MR-J2 memory backup battery used in MELSERVO MR-J2 series servo amplifiers, where it retains absolute position data for the encoder system. 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.\u003c\/p\u003e\u003cp\u003eProtect stored programs, RAM, and real-time clock data on Mitsubishi, Eternacell, Maxell, Hitachi, and other industrial control systems with this 3.6V 2100mAh 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.\u003c\/p\u003e\u003cp\u003eThis battery cross-references to Mitsubishi A Series, Mitsubishi A0J2-D71 Positioning Module, Mitsubishi A0J2-DC24 Controller, Mitsubishi A1FX CPU Robot Control, Mitsubishi A1FXCPU, and Mitsubishi A1S, plus 36 additional cross-referenced part numbers, giving you a single verified replacement across these part numbers.
