It matches OEM part numbers 5B10R32748, L17C4PE1, L17M4PE1, L17L4PE1, 928QA232H, and SB10W67305. The slim 3.50mm profile fits within the S730's tight chassis without modification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eYoga S730-13IWL series fit:\u003c\/strong\u003e\n    All S730-13IWL variants share the same 15.36V four-cell Li-Polymer architecture, connector pinout, and BMS handshake protocol. This cell covers the 81J0 board revision and all regional SKUs listed under that chassis.\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 the S730 platform. The BMS negotiated correctly with the EC firmware, reported voltage accurately at each state-of-charge step, and held charge termination at the correct cutoff without triggering over-voltage protection.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install recalibration on the S730:\u003c\/strong\u003e\n    After fitting this cell, run one full discharge until the laptop hibernates on its own, then charge uninterrupted to 100% without waking the system. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap on this platform.\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 S730 shuts down at 20–30% after a battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe S730's fuel gauge IC stores a learned discharge curve from the old cell in EEPROM. When a new cell goes in, the IC maps the old curve onto different chemistry data and calls the voltage cliff too early. The laptop interprets a normal mid-discharge voltage as critical and triggers an emergency shutdown. Running one full discharge-to-hibernate cycle forces the IC to relearn where the actual voltage floor sits on the new cell, typically around 14.4V under load.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBIOS reporting the replacement cell as 0% or unknown health\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe S730 BIOS reads battery health from EEPROM flags written by the original Lenovo cell during factory calibration. A new cell arrives with a blank or mismatched EEPROM state, so the BIOS flags it as unknown or poor before any calibration data exists. This is not a fault with the cell itself. Perform one full discharge-to-hibernate followed by a complete uninterrupted charge to 100% — the BIOS learn cycle writes fresh health data and the warning clears on the next boot.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409650024538,"sku":"BWCS-LVS730NB-1","price":66.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409650057306,"sku":"BWCS-LVS730NB-2","price":78.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409650090074,"sku":"BWCS-LVS730NB-3","price":87.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LVS730NB-1.webp?v=1779580312","url":"https:\/\/batteryweb.com\/products\/lenovo-yoga-s730-replacement-battery-1536v-2650mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
