It replaces a degraded or failed original cell and restores full portable operation. It cross-references multiple OEM part numbers including L17M3PB1, L17C3PB0, L17D3PB0, and 5B10Q71251.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eIdeaPad 330-15ICH and 330-17ICH fitment:\u003c\/strong\u003e\n    Both the 15-inch and 17-inch 330 ICH variants share the same 11.34V three-cell Li-Polymer architecture, connector pinout, and BMS handshake protocol. One battery covers the full ICH sub-family 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 IdeaPad 330-series hardware. The BMS authenticated correctly, the fuel gauge IC initialised without error flags, and the BIOS accepted the cell without throwing an unknown battery warning on first boot.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration cycle:\u003c\/strong\u003e\n    After fitting this battery, run one full discharge down to hibernate cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears in Lenovo Vantage 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\"\u003eLaptop shuts down at 20–30% remaining after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe IdeaPad 330 BIOS maps its shutdown threshold against the old cell's discharge curve stored in EEPROM. A new cell with a different internal resistance profile hits a voltage cliff under combined CPU and display load before the fuel gauge IC registers zero. The system reads a valid percentage but the cell voltage drops below the BMS protection floor under load, triggering an abrupt cutoff. Run two full calibration cycles — full discharge to hibernate, full uninterrupted charge to 100% — and the fuel gauge IC will remap its curve against the new cell, resolving the premature shutdowns.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBIOS reports battery health as \"Poor\" or \"Replace Now\" on first boot\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis flag is triggered by the BIOS comparing the new cell's EEPROM data against the health history logged from the old battery. It is not a defect in the replacement cell. The Lenovo EC (embedded controller) needs at least one complete learn cycle to overwrite the cached health data. Charge to 100%, discharge fully to hibernate cutoff, then charge back to 100% without interruption — after that cycle the health status in Lenovo Vantage will update to reflect the actual condition of the new cell.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409607917658,"sku":"BWCS-LVP330NB-1","price":97.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409607950426,"sku":"BWCS-LVP330NB-2","price":111.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409607983194,"sku":"BWCS-LVP330NB-3","price":122.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LVP330NB-1.webp?v=1779580190","url":"https:\/\/batteryweb.com\/products\/lenovo-ideapad-330-15ich-81fk00a5au-replacement-battery-1134v-3900mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
