It replaces OEM part numbers L14M4P72 and L14S4P72. Fit models include the Yoga 3 14, Yoga 3 1470, Yoga 700 14ISK, and Yoga 700-14ISK(80QD006UGE), among others.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eYoga 3 14 and Yoga 700-14ISK platform:\u003c\/strong\u003e\n    Both the Yoga 3 14 and Yoga 700-14ISK use the same 7.4V two-cell Li-Polymer pack with a shared connector pinout and BMS handshake protocol. L14M4P72 and L14S4P72 are interchangeable references for the same physical cell configuration on this platform.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell on a Yoga 3 14 unit and confirmed the BMS communicates correctly with the EC, reports accurate state-of-charge data, and holds charge through a full discharge-to-cutoff cycle without triggering a protection fault.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle recalibration on Yoga 3 14:\u003c\/strong\u003e\n    After installing, run one full discharge until the laptop hibernates at low battery, 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 L14M4P72\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Lenovo EC reads health data from EEPROM values written by the original cell's fuel gauge IC. A new cell carries different EEPROM state, so the BIOS flags it as degraded or unknown immediately after installation — even when the cell is fully intact. This is not a fault with the replacement. Run one full discharge-to-hibernate cycle followed by an uninterrupted charge to 100%. After two to three cycles, the fuel gauge IC recalibrates against the new cell's actual chemistry and the health warning clears.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eYoga 3 14 shutting down at 20–30% charge shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the cell cannot hold voltage above the EC's cutoff threshold under combined CPU and display load — even though the OS gauge still reads 20–30%. The fuel gauge IC has not yet mapped the new cell's voltage-to-capacity curve, so the OS overestimates remaining charge. The fix is calibration: discharge the laptop to hibernate under normal use, then charge to 100% without interruption. Repeat two cycles and the gauge will track the actual voltage cliff accurately, eliminating premature shutdowns.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409766547546,"sku":"BWCS-LVY314NB-1","price":51.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409766580314,"sku":"BWCS-LVY314NB-2","price":59.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409766613082,"sku":"BWCS-LVY314NB-3","price":65.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LVY314NB-1.webp?v=1779580789","url":"https:\/\/batteryweb.com\/products\/lenovo-yoga-3-14-replacement-battery-74v-6050mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
