It fits the 14ALC6, 14ITL6, 15ALC6, 15ITL6, and more than 22 additional IdeaPad 3 variants that share the same battery bay and connector. Install it when the original cell has degraded and the laptop can no longer hold a useful charge away from the adapter.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eIdeaPad 3 ALC6 and ITL6 platform fit:\u003c\/strong\u003e\n    Lenovo uses the same 7.68V two-cell Li-Polymer architecture and identical ZH1.25 connector across both the AMD (ALC6) and Intel (ITL6) IdeaPad 3 chassis. The BMS handshake and charge-control pin-out are identical, so one cell 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 a full charge-discharge cycle on an IdeaPad 3 15ITL6. The BMS accepted the cell, charge current ramped correctly from CC to CV, and the protection circuit triggered at the expected low-voltage cutoff without tripping a fault flag.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBIOS learn cycle after install:\u003c\/strong\u003e\n    After fitting this battery, run the laptop down until it hibernates from low charge, then charge uninterrupted to 100% before using it again. This one cycle resets the BIOS battery learn counter and clears the false \"poor health\" or \"replace battery\" warning that appears after every cell swap on IdeaPad 3 units.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the IdeaPad 3 shuts down at 20–30% remaining after a battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe fuel gauge IC on the IdeaPad 3 motherboard stores learned discharge curves from the previous cell in non-volatile memory. When a new cell goes in, those old curves no longer match the actual voltage profile of the replacement. Under combined CPU and display load, the IC reads the voltage drop as hitting empty far earlier than it actually is, triggering an emergency shutdown. The fix is a full calibration cycle — drain fully to hibernate cutoff, then charge to 100% without interruption. After two to three of these cycles the fuel gauge IC recalibrates its curve to the new cell and the shutdowns stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eNew battery shows wrong Wh rating in Lenovo Vantage or Device Manager\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Wh figure shown in Lenovo Vantage and Windows Device Manager is pulled from the EEPROM data embedded in the battery's protection circuit board, not measured live from the cell. Replacement cells sometimes carry a rated Wh value in that EEPROM that differs slightly from the actual chemistry capacity. This is a data field difference, not a fault — the cell still delivers its full electrochemical capacity. If Vantage shows a figure other than 37.25Wh, confirm actual charge acceptance by running one full cycle and checking that the laptop reaches 100% on the charge indicator.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409600249946,"sku":"BWCS-LVV152NB-1","price":64.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409600282714,"sku":"BWCS-LVV152NB-2","price":75.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409600315482,"sku":"BWCS-LVV152NB-3","price":84.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LVV152NB-1.webp?v=1779580190","url":"https:\/\/batteryweb.com\/products\/lenovo-ideapad-3-14alc6-replacement-battery-768v-4850mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
