It replaces OEM part numbers L16L6PC1, L16C6PC1, L16M6PC1, 5B10M53743, 5B10M53744, and 5B10M53745. Install it when the original cell no longer holds a charge or causes unexpected shutdowns.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eYoga 720-15IKB compatibility:\u003c\/strong\u003e\n    All Yoga 720-15IKB variants share the same 11.56V three-cell battery rail, physical connector pinout, and BMS handshake protocol — which is why the L16L6PC1, L16C6PC1, and L16M6PC1 part numbers all cross-reference to the same physical cell pack. Variant-specific units like the 80X70041GE and 80X70058GE draw from the same battery bus.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through full charge and discharge cycles on a Yoga 720-15IKB unit. The BMS completed handshake without fault codes, the charge controller accepted current across all three cells evenly, and the BIOS recognised the pack without triggering an unknown battery warning.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on the Yoga 720:\u003c\/strong\u003e\n    After installing, run one full discharge until the laptop hibernates, then charge uninterrupted to 100% without using the machine. This forces the BIOS battery learn cycle to reset against the new cell data 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 battery health as poor immediately after replacement\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Yoga 720-15IKB BIOS reads health data from EEPROM stored on the battery pack. When you swap cells, the EEPROM on the new pack carries factory-baseline data that doesn't match the charge history the BIOS expects. This creates a false \"poor health\" or \"replace soon\" flag in Lenovo Vantage and the BIOS battery menu. Running one full discharge-to-hibernate cycle followed by an uninterrupted charge to 100% allows the BIOS learn cycle to write new baseline data and clear the flag. If the warning persists after two calibration cycles, check BIOS version — firmware older than a certain revision on this platform misreads Li-Polymer Wh ratings against its stored Li-ion reference table.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shutting down at 20–30% shown on the Yoga 720-15IKB\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage-cliff failure, not a gauge error. Under combined CPU and display load, the cell voltage drops faster than the fuel gauge IC can track, and the pack hits the BMS low-voltage cutoff while the OS still reads 20–30% remaining. The fuel gauge IC needs two to three full calibration cycles against the new cell before its discharge curve model stabilises. Discharge fully to hibernate cutoff each time, charge to 100%, and the gap between reported and actual capacity will close. After three cycles, the shutdown threshold should align with a displayed level below 5%.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409690853466,"sku":"BWCS-LVY721NB-1","price":86.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409690886234,"sku":"BWCS-LVY721NB-2","price":101.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409690919002,"sku":"BWCS-LVY721NB-3","price":112.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LVY721NB-1.webp?v=1779580474","url":"https:\/\/batteryweb.com\/products\/lenovo-yoga-720-15ikb-replacement-battery-1156v-6150mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
