It also cross-references OEM part numbers Y07HK and FY8XM. Install it when the original cell no longer holds a charge or fails to register in Chrome OS.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eChromebook 11 3180, 3189, and 3100 fitment:\u003c\/strong\u003e\n    All three models share the same 11.1V battery rail, physical connector, and BMS handshake protocol. One cell covers the entire range without any modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on a Chromebook 11 3180. The BMS accepted the new cell without tripping overcurrent protection, and the fuel gauge IC began tracking state-of-charge correctly after two calibration cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBIOS learn cycle after install:\u003c\/strong\u003e\n    After fitting this cell, run the Chromebook down until it hibernates on low battery, then charge it uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the false \"battery health poor\" warning that appears after every cell swap on these Dell Chromebooks.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Chromebook 11 shuts down at 20–30% after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe fuel gauge IC on these boards stores discharge curve data calibrated to the original cell. A new cell has a slightly different internal resistance profile, so the IC misreads state-of-charge under load. When the CPU and display draw peaks simultaneously, the cell voltage drops faster than the IC expects, and the system interprets it as a low-battery shutdown. Two full discharge-to-hibernate and charge-to-100% cycles re-calibrate the IC against the new cell's actual curve. After that, the gauge tracks accurately and the early shutdowns stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBIOS reporting 0% or \"unknown\" battery immediately after fitting the new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe BIOS reads battery identity and health data from the cell's EEPROM. When a replacement cell arrives, the EEPROM contains data that does not match the charge history the BIOS expects, so it flags the battery as unknown or reports 0%. This is not a fault with the cell. Boot the Chromebook on AC power, let Chrome OS fully load, then unplug and allow it to discharge normally. The BIOS will re-read the EEPROM and update battery status correctly — confirm by checking chrome:\/\/system and locating the battery_status field.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409708777562,"sku":"BWCS-DEC113NB-1","price":62.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409708810330,"sku":"BWCS-DEC113NB-2","price":71.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409708843098,"sku":"BWCS-DEC113NB-3","price":80.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DEC113NB-1.webp?v=1779580499","url":"https:\/\/batteryweb.com\/products\/dell-chromebook-11-3180-replacement-battery-111v-3550mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
