It replaces OEM part numbers L12M2P01, L12N2P01, 121500184, 1ICP4\/83\/102-2, and 1ICP4\/83\/103-2. It sits inside the chassis and powers the display, Intel Atom Z2760 processor, and all onboard peripherals.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eThinkPad Tablet 2 and Miix 10 fitment:\u003c\/strong\u003e\n    These models share the same flat Li-Polymer cell format, 3.75V nominal rail, and two-wire BMS connector pinout. The Z2760 platform draws from the same power architecture, which is why one cell covers all three variants.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on a ThinkPad Tablet 2 unit. The BMS handshake completed on first connection, the charge IC accepted current without fault, and the fuel gauge began tracking state of charge correctly.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration after swap:\u003c\/strong\u003e\n    After installing this battery, run the tablet down to automatic shutoff — do not force it off — then charge uninterrupted to 100%. This gives the fuel gauge IC a full reference cycle against the new cell and corrects the inaccurate percentage readings that almost always appear after a battery change.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the ThinkPad Tablet 2 shuts down at 15–25% remaining\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Intel Atom Z2760 platform draws a combined load from the IPS display backlight and Wi-Fi radio simultaneously. At around 3.5V cell voltage, this combined draw causes a brief voltage sag that the BMS reads as undervoltage and triggers a protective cutoff — even though the fuel gauge still shows charge remaining. The old cell makes this worse as capacity fades, because the internal resistance rises and the sag deepens faster. A new cell with lower internal resistance holds the voltage rail above the cutoff threshold longer, eliminating the premature shutdown.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePercentage jumping or freezing immediately after installation\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe ThinkPad Tablet 2 stores fuel gauge calibration data tied to the original cell's charge curve. When a new cell goes in, that stored data no longer matches the actual cell, so the OS reports incorrect or erratic percentages — sometimes freezing at a fixed number or jumping suddenly. This is a calibration mismatch, not a faulty battery. Run one complete discharge cycle to automatic shutoff, then charge straight to 100% without interruption. After that cycle, the fuel gauge IC rewrites its reference data against the new cell and the percentage display stabilises.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43425837744218,"sku":"BWCS-LVM100SL-1","price":46.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43425837776986,"sku":"BWCS-LVM100SL-2","price":53.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43425837809754,"sku":"BWCS-LVM100SL-3","price":59.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LVM100SL-1.webp?v=1779929903","url":"https:\/\/batteryweb.com\/products\/lenovo-thinkpad-tablet-2-3679-101-replacement-battery-375v-6600mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
