It fits models across both series, including the L560-7CD and ThinkPad L560(20F10022GE), and matches the OEM connector, form factor, and BMS communication protocol. Compatible OEM part numbers include SB10H45073, SB10H45074, SB10H45071, 00NY488, 00NY489, and 00NY486.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eL560 and L570 fitment:\u003c\/strong\u003e\n    Both series run the same 10.8V battery rail, use the same physical connector, and expect the same BMS handshake from the EEPROM. A single cell covers both platforms without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell on an L560 and monitored BMS communication through full charge and discharge cycles. The BIOS recognised the battery as a valid Lenovo cell, charge current behaved correctly, and no BMS fault codes were logged.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle reset on ThinkPad firmware:\u003c\/strong\u003e\n    After installing, run one full discharge to hibernate cutoff, then charge uninterrupted to 100%. This forces the ThinkPad battery learn cycle to reset against the new cell and clears the inaccurate health warning that appears after every cell swap.\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 after swapping cells on the L560\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe ThinkPad BIOS reads health data from the EEPROM embedded in the battery pack. When a new cell is installed, the EEPROM contains factory defaults that do not yet match the BIOS's learned charge history from the old pack. The firmware flags this mismatch as degraded health. Running one full discharge-to-hibernate followed by an uninterrupted charge to 100% allows the battery learn cycle to write new baseline data and clear the warning.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eL560 shuts down at 20–30% shown on the fuel 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 gauge still uses discharge curve data from the old, degraded cell, so its percentage readout drifts early. The cell hits a voltage floor the hardware cannot sustain under combined CPU and display load before the gauge reaches zero. Two to three full discharge-and-recharge cycles recalibrate the IC — after that, shutdown should align with a displayed charge of 5% or below, with the cell resting above 10.0V at cutoff.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409707237466,"sku":"BWCS-LVT560NB-1","price":111.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409707270234,"sku":"BWCS-LVT560NB-2","price":127.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409707303002,"sku":"BWCS-LVT560NB-3","price":139.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LVT560NB-1.webp?v=1779580516","url":"https:\/\/batteryweb.com\/products\/lenovo-thinkpad-l560-replacement-battery-108v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
