It powers the real-time clock and SRAM backup memory inside the YRC1000, keeping robot programs, system parameters, and job data intact when mains power drops. Fits both GP7 Body and GP8 Body configurations sharing this controller.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGP7 and GP8 Body compatibility:\u003c\/strong\u003e\n    Both manipulator variants run through the YRC1000 controller housing and share the same backup battery socket, voltage rail, and BMS handshake — a single cell part covers both robot bodies without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We confirmed open-circuit voltage on delivery, verified the cell seats correctly in the HW1483880-A socket, and checked that the BMS accepts the cell and clears the low-battery flag under controlled conditions.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eHot-swap requirement on the YRC1000:\u003c\/strong\u003e\n    Replace this cell only while the YRC1000 is powered on and in normal operating status. Removing the battery with the controller off drops SRAM voltage immediately — all robot programs, tool data, and job files are erased and must be reloaded from a backup device.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the YRC1000 loses program memory after a battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe YRC1000 uses static RAM to hold robot programs, interference zone data, and system variables. That SRAM requires a continuous voltage above approximately 2.0V to retain data — the backup cell provides that voltage the moment mains power is removed. If the cell is pulled while the controller is off, there is no buffer and SRAM contents are gone in seconds. This is not a fault in the new cell; it is the expected result of breaking supply to volatile memory. Reload all programs from a teach pendant backup or PC backup file after any cold swap.\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\"\u003eThe YRC1000 latches a BATTERY LOW alarm in the system fault log — fitting a new cell does not automatically clear it. The controller needs the alarm acknowledged manually through the pendant: navigate to Main Menu → System Info → Alarm and clear the latched fault. If the alarm returns within hours, check that the cell is fully seated and the connector is locked; a partial connection reads as low voltage even with a fresh cell. A properly seated new cell should read at or above 3.6V on the pendant's battery status screen once the float charge cycle completes.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43415966384218,"sku":"BWCS-YMC100SL-1","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43415966416986,"sku":"BWCS-YMC100SL-2","price":31.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43415966449754,"sku":"BWCS-YMC100SL-3","price":34.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-YMC100SL-1.webp?v=1779758652","url":"https:\/\/batteryweb.com\/products\/yaskawa-yrc1000-gp7-body-replacement-battery-36v-2700mah-li-socl2","provider":"BatteryWeb","version":"1.0","type":"link"}
