It fits the full Elite x2 1012 G1 lineup, including the Y0F40UP, Z9M72PC, V5B96US, and X5F29US configurations, plus 166 additional variants. Compatible OEM part numbers include 812060-2B1, 812205-001, HSTNN-DB7F, HSTNN-I72C, and MC04XL.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eElite x2 1012 G1 platform compatibility:\u003c\/strong\u003e\n    All Elite x2 1012 G1 units share the same 7.7V battery rail, MG04XL connector pinout, and BMS handshake protocol regardless of regional SKU. One cell covers the entire model range without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge, discharge, and BMS handshake verification on the Elite x2 1012 G1 platform. The BMS accepted the cell without fault codes, balanced cells correctly, and reported capacity within expected tolerance.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle calibration on the Elite x2 1012 G1:\u003c\/strong\u003e\n    After installing, run one full discharge to hibernate cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health or low-capacity 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 installing a new MG04XL cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Elite x2 1012 G1 BIOS reads health data from the battery's EEPROM, which still carries charge-cycle counts and degradation flags from the old cell at the moment of swap. A new cell arrives with its own EEPROM baseline, and the BIOS treats the mismatch as evidence of a worn pack. This is a calibration state, not a hardware fault. Run the full discharge-to-hibernate then uninterrupted charge-to-100% cycle once, and the BIOS will rewrite the health register against the new cell's actual data.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eElite x2 1012 G1 shutting down at 20–30% charge shown on screen\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 voltage curve. The gauge reports 20–30% remaining, but the cell hits its low-voltage cutoff before the display figure reaches zero. Under combined CPU and display load, voltage sag accelerates this cliff. Complete two to three full discharge-to-hibernate and full charge cycles — after that, the gauge IC aligns its curve to the new cell and the shutdowns stop. Confirm the cell rests at 3.85V per cell at 50% displayed charge once calibrated.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409690656858,"sku":"BWCS-HPX101NB-1","price":74.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409690689626,"sku":"BWCS-HPX101NB-2","price":86.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409690722394,"sku":"BWCS-HPX101NB-3","price":95.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HPX101NB-1.webp?v=1779580454","url":"https:\/\/batteryweb.com\/products\/hp-elite-x2-1012-g1-y0f40up-replacement-battery-77v-4750mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
