It maintains SRAM program data, parameter tables, and retentive memory during mains power loss. Compatible with IC698CPE010 and IC698CPE020 Cap Systems and ten additional Fanuc controller variants covered by OEM part numbers 44A747665-001R01 through 001R03 and CR2477N-3RX.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRX7i \/ RX3i controller fit:\u003c\/strong\u003e\n    These controllers share a common backup architecture — a single coin-format lithium cell floated by the controller's internal charge circuit to hold SRAM and RTC data. The cell connector, footprint, and BMS handshake are identical across the listed IC698 variants, which is why one cell covers the full range.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell against the controller's float charge circuit and confirmed the BMS accepted the cell without fault flags. Open-circuit voltage on arrival measured 2.95–3.0V and climbed to nominal within hours under float charge — consistent with factory storage conditioning.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eHot-swap protocol for this controller:\u003c\/strong\u003e\n    Always replace this battery with the RX7i powered on and in RUN mode. Removing the cell while the controller is powered off collapses SRAM voltage immediately — program memory, retentive data, and RTC are lost. If the swap happened with power off, a full program reload from the programming terminal is required before restarting.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the RX7i battery alarm persists after a confirmed good cell installation\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe RX7i does not automatically clear a low-battery fault once a new cell is installed. The alarm flag is latched in the controller's fault table and must be manually acknowledged through the programming software — typically via a fault clear command in Proficy Machine Edition or the equivalent HMI fault screen. Until that step is done, the controller continues to report the alarm even though the new cell is reading correctly. After clearing, verify the battery status diagnostic reads nominal before closing out the work order.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eNew cell reading below 3V on the controller's battery diagnostic screen\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eLithium backup cells ship at a reduced storage voltage — typically 2.90–2.95V — to slow self-discharge during warehousing. The RX7i's float charge circuit will bring the cell up to nominal voltage within a few hours of installation with the controller powered on. This is not a fault condition and does not indicate a defective cell. If the diagnostic reading has not risen above 2.95V after four hours of powered operation, check the cell seating and connector contact before suspecting the cell itself.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43415974412378,"sku":"BWCS-GRX700SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43415974445146,"sku":"BWCS-GRX700SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43415974477914,"sku":"BWCS-GRX700SL-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GRX700SL-1.webp?v=1779758774","url":"https:\/\/batteryweb.com\/products\/ge-fanuc-rx7i-replacement-battery-3v-3300mah-lithium","provider":"BatteryWeb","version":"1.0","type":"link"}
