It replaces OEM part numbers L09S6Y14, L09M6Y14, L09C6Y14, and the full 57Y6xxx and 121000xxx series. Fits S10-3 variants including the 06474CU and 064735U builds.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eS10-3 variant coverage:\u003c\/strong\u003e\n    The S10-3 line spans multiple sub-models — 0647, 06474CU, 064735U among them — but all share the same 11.1V three-cell rail and the same connector footprint. The BMS handshake protocol is consistent across this platform, so one cell spec 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 through charge and discharge cycles on an S10-3 unit. The BMS communicated correctly with the EC firmware, charge current ramped normally through CC\/CV stages, and no protection tripping occurred at idle or moderate CPU load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on the S10-3:\u003c\/strong\u003e\n    After fitting this cell, run the netbook down to hibernate-cutoff on battery only — no AC — then charge uninterrupted to 100%. This forces the BIOS battery learn cycle to reset against the new cell and clears the false \"poor health\" warning that appears immediately after any 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\"\u003eBIOS reporting battery health as poor after replacement on the S10-3\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe S10-3 EC reads health data from the battery's EEPROM on first contact. When a new cell arrives, that EEPROM data doesn't match the discharge history the BIOS expects, so it flags the battery as degraded — even when the cell is brand new. This is not a fault with the replacement cell. One full discharge-to-hibernate followed by an uninterrupted charge to 100% resets the learn cycle. After two to three cycles, the BIOS health readout normalises.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eIdeaPad S10-3 shutting down at 20–30% charge shown\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe fuel gauge IC on the S10-3 calibrates against the original cell's discharge curve. Fit a new cell and the IC's stored curve no longer matches actual cell chemistry, so the percentage readout drifts — the system hits a voltage floor the IC doesn't recognise and shuts down before the displayed figure reaches zero. The fix is calibration: discharge fully to hibernate, charge to 100% without interruption, repeat twice. By the third cycle the fuel gauge IC has mapped the new cell's voltage curve and the shutdown-at-30% behaviour stops. Check that battery voltage under light load reads above 10.8V at the point the shutdown previously triggered — anything below that confirms the old cell data was the cause.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410798346330,"sku":"BWCS-IBS13NT-1","price":70.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43410798379098,"sku":"BWCS-IBS13NT-2","price":83.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43410798411866,"sku":"BWCS-IBS13NT-3","price":92.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-IBS13NT-1.webp?v=1779581158","url":"https:\/\/batteryweb.com\/products\/lenovo-idideapad-s10-3-replacement-battery-111v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
