It covers a wide range of OEM part numbers including 57Y6454, L09S6Y02, L09C6Y02, and L09L6Y02. If the original cell no longer holds charge or fails to register in Windows, this cell fits the same bay and connector.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eG460 and G560 shared battery platform:\u003c\/strong\u003e\n    Both the G460 and G560 use the same 11.1V three-cell battery bay, connector pinout, and BMS communication protocol. Lenovo carried this platform across multiple SKUs — that is why over 25 OEM part numbers cross-reference to the same physical cell.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell on a G460 and monitored BMS handshake through a full charge cycle. The protection circuit triggered correctly at 12.6V full charge and cut off cleanly at low-voltage threshold without false trips.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle calibration on the G460:\u003c\/strong\u003e\n    After installation, run one complete discharge to hibernate-cutoff, then charge uninterrupted to 100%. This forces the BIOS battery learn cycle to reset against the new cell chemistry and clears the inaccurate health warning that appears after every cell swap on IdeaPad hardware.\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 immediately after fitting a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe IdeaPad BIOS stores battery health data in EEPROM tied to the original cell's cycle count and internal resistance profile. When a new cell is installed, that stored data does not automatically clear — the BIOS reads residual values from the old cell and flags the battery as degraded. This is not a fault with the replacement. Run one full discharge to hibernate-cutoff followed by an uninterrupted charge to 100% to trigger the learn cycle and write fresh calibration data to EEPROM.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down at 20–30% charge shown on the gauge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC has not yet calibrated against the new cell's actual voltage curve. The IC is still using the old cell's discharge profile, so it misreads the voltage cliff — the point where cell voltage drops sharply under CPU and display load — as a hard shutdown threshold. The laptop cuts power because the IC thinks 0% has been reached when the gauge still shows 20–30%. Two to three full discharge and recharge cycles recalibrate the fuel gauge IC and push the shutdown point back to the correct near-zero level.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410807259226,"sku":"BWCS-LVG460NB-1","price":99.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43410807291994,"sku":"BWCS-LVG460NB-2","price":112.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43410807324762,"sku":"BWCS-LVG460NB-3","price":122.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LVG460NB-1.webp?v=1779581158","url":"https:\/\/batteryweb.com\/products\/lenovo-ideapad-g460-replacement-battery-111v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
