It fits PLCs and CNC controllers that use this cell format to back up SRAM program memory and the real-time clock during mains power loss. Confirm your existing cell's markings match one of those part numbers before installation.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCNC and PLC controller compatibility:\u003c\/strong\u003e\n    Fanuc CNC systems referencing A02B-0120-K106 and A20B-0130-K106 use this cell on a 3V SRAM retention rail. The connector and cell format are shared across multiple controller generations, which is why several OEM part numbers map to the same physical cell.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell against a PLC backup circuit and confirmed the BMS-free Li-MnO2 chemistry holds a stable open-circuit voltage at 3.0V, with no protection circuitry interfering with the controller's own low-battery detection threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eHot-swap procedure for this cell:\u003c\/strong\u003e\n    Always replace this battery with the PLC or CNC controller powered on and in RUN mode. Removing the cell while the controller is off collapses the SRAM retention voltage immediately — program memory is lost and a full reload from the programming device will be required.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePLC losing program memory after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSRAM on most PLCs and Fanuc CNC controllers is volatile — it holds data only as long as a voltage above the retention threshold (typically 2.0–2.5V) is present. The moment the old cell is removed and before the new one seats, that rail drops to zero if the controller is off. Even a two-second gap is enough to wipe the SRAM completely. The only recovery is reloading the program from a backup on the programming device — there is no in-controller restore.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery alarm not clearing after a confirmed good installation\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eMost PLCs latch a low-battery fault flag in software rather than clearing it automatically when a new cell is detected. The controller reads the alarm state from a register, not directly from live cell voltage. After fitting the new cell, navigate to the diagnostic or alarm screen in your programming software and clear the fault flag manually. On Fanuc systems, this is typically done via the SYSTEM \u0026gt; BATTERY screen or by clearing the relevant PMC alarm code.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43415985782874,"sku":"BWCS-PLC265SL-1","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43415985815642,"sku":"BWCS-PLC265SL-2","price":35.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43415985848410,"sku":"BWCS-PLC265SL-3","price":39.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PLC265SL-1.webp?v=1779758956","url":"https:\/\/batteryweb.com\/products\/panasonic-replacement-battery-3v-5000mah-li-mno2","provider":"BatteryWeb","version":"1.0","type":"link"}
