It replaces OEM part numbers L19C4PF4, L19M4PF4, SB10W65282, SB10W65284, 5B10W65273, 5B10W65276, and 5B10W65297. The cell fits the 14ARE05, Yoga Slim 7-14ARE, Yoga 14s, and Yoga Slim 7 14ITL05 (82A3003CUE), among others.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eYoga Slim 7 series compatibility:\u003c\/strong\u003e\n    These models share the same four-cell 15.36V architecture, identical connector pinout, and BMS handshake protocol — which is why one part number covers both the AMD 14ARE05 and Intel 14ITL05 variants.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell on the Yoga Slim 7 14ARE05 platform and confirmed the BMS completed a full charge cycle, communicated state-of-charge data to the firmware, and held the rated voltage across a sustained CPU-plus-display load without triggering a low-voltage cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle calibration on the Yoga Slim 7:\u003c\/strong\u003e\n    After installing, run one full discharge to the hibernate cutoff, then charge uninterrupted to 100%. 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\"\u003eBIOS reporting poor battery health after swapping the L19C4PF4 cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eWhen a new cell goes in, the BIOS still holds EEPROM data from the old battery — charge cycles, wear percentage, and last-known capacity. Until the firmware re-learns the new cell's actual discharge curve, it compares current readings against stale data and flags the battery as degraded. This is a firmware calibration issue, not a fault with the replacement cell. Run one complete discharge-to-hibernate then a full uninterrupted charge — after that cycle the BIOS learn routine overwrites the old EEPROM values and the health flag clears.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eYoga Slim 7 shutting down at 20–30% charge remaining\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe fuel gauge IC estimates remaining capacity based on voltage curves loaded during calibration. A new cell with different internal resistance than the worn original will cause the gauge to misread voltage sag under full CPU and display load — the laptop sees what looks like a near-empty cell and cuts power before the gauge hits zero. The underlying cause is an uncalibrated fuel gauge IC, not a faulty cell. Run two full discharge-to-hibernate cycles followed by uninterrupted charges to 100%; the gauge recalibrates against the new cell's actual voltage floor, and the premature shutdowns stop.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409656709210,"sku":"BWCS-LVY714NB-1","price":104.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409656741978,"sku":"BWCS-LVY714NB-2","price":120.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409656774746,"sku":"BWCS-LVY714NB-3","price":131.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LVY714NB-1.webp?v=1779580312","url":"https:\/\/batteryweb.com\/products\/lenovo-yoga-7-slim-14are05-replacement-battery-1536v-3850mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
