It fits controllers listed under 1070085767-102, F098218, 11929GW, and GEW11-W09, among others. Its sole job is to hold SRAM contents and RTC data when mains power drops.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eWhy these controllers share this cell:\u003c\/strong\u003e\n    All listed models route backup power through the same 6V Li-MnO2 rail. The BMS on each expects a flat discharge curve above 5V to keep SRAM live. A lower-voltage substitute won't hold that threshold long enough under load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran the 2CR14250SE under a simulated SRAM retention load and confirmed the cell holds above 5.5V through the rated 800mAh capacity. The BMS flagged no under-voltage trips during the test cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eHot-swap rule for this controller:\u003c\/strong\u003e\n    Always replace this cell with the PLC powered on and in RUN mode. Removing the battery while the controller is off drains SRAM instantly — the program is gone. If that happens, a full reload from the programming device is required before the controller will run.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePLC battery alarm not clearing after the new cell is seated\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eFitting a new cell does not automatically dismiss the battery fault in most controllers using this backup circuit. The alarm flag is written to a status register and must be cleared manually through the programming software — it will not self-reset just because voltage is now good. Connect a programming device, navigate to the diagnostics or system status block, and acknowledge the battery alarm from there. Until you do, the PLC may continue logging the fault even though the cell is fully functional.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eNew cell reading below 6V on the controller's battery status screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-MnO2 cells ship at a storage voltage that can sit measurably below the rated open-circuit 6V. Once seated, the cell draws a small float current from the PLC backup circuit and recovers to full voltage within a few hours. This is not a fault and does not indicate a weak or incorrect cell. If voltage has not climbed to at least 5.8V after 24 hours in an energised controller, reseat the cell and check for oxidation on the battery contacts.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43415965794394,"sku":"BWCS-FDW090SL-1","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43415965827162,"sku":"BWCS-FDW090SL-2","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43415965859930,"sku":"BWCS-FDW090SL-3","price":32.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-FDW090SL-1.webp?v=1779758582","url":"https:\/\/batteryweb.com\/products\/fdk-1070085767-102-replacement-battery-6v-800mah-li-mno2","provider":"BatteryWeb","version":"1.0","type":"link"}
