It fits the 2-in-1 convertible Chromebook across multiple revisions, including the Yoga 11e 20GC and 20GE. Voltage, connector, and BMS handshake match the original cell specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eYoga 11e 20GC and 20GE compatibility:\u003c\/strong\u003e\n    These revisions share the same 11.4V three-cell Li-Polymer architecture, connector pinout, and BMS communication protocol — which is why a single cell covers all listed variants without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and load on the Yoga 11e platform. The BMS completed full charge handshake, protection circuits responded correctly to load spikes, and cell voltage held stable under sustained CPU and display activity.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration for the Yoga 11e:\u003c\/strong\u003e\n    After fitting this cell, run the Chromebook down to automatic hibernate cutoff, then charge uninterrupted to 100% without using the device. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Yoga 11e shuts down at 20–30% after a battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe firmware fuel gauge IC builds a discharge model against the original cell's EEPROM data. After a swap, that model no longer matches the new cell's actual voltage curve. The system reads a voltage drop at mid-charge and interprets it as a near-empty condition. Running two to three full discharge-to-hibernate and uninterrupted charge cycles forces the fuel gauge IC to rebuild its model against the new cell — shutdowns at false percentages stop once the recalibration completes.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBIOS reporting the replacement battery as poor health or unknown\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Lenovo BIOS reads health data from the cell's EEPROM, not from live voltage measurement. When a new cell is installed, the EEPROM registers zero cycles but the BIOS compares its internal threshold data against the previous cell's learned profile — flagging the mismatch as degraded or unknown. This is not a fault with the replacement cell. Run one full learn cycle: discharge to hibernate cutoff, then charge to 100% uninterrupted. The BIOS health status clears to normal once the learn cycle writes fresh data to match the new cell.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409734795354,"sku":"BWCS-LVY112NB-1","price":77.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409734828122,"sku":"BWCS-LVY112NB-2","price":91.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409734860890,"sku":"BWCS-LVY112NB-3","price":101.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LVY112NB-1.webp?v=1779580625","url":"https:\/\/batteryweb.com\/products\/lenovo-thinkpad-yoga-11e-chromebook-replacement-battery-114v-3600mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
