It fits the display unit — the tablet half of the 2-in-1. Compatible OEM part numbers include BV02XL, 776621-001, HSTNN-IB6Q, and TPN-I116, covering the Envy X2 13-J000 series and related variants.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eEnvy X2 13\" display unit compatibility:\u003c\/strong\u003e\n    These models share the same flat Li-Polymer cell, 7.6V voltage rail, and connector pinout on the detachable display board. The BMS handshake is identical across the J000 series variants, so one cell covers the full range.\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 the Envy X2 platform. The BMS accepted the cell without fault flags, balanced correctly at full charge, and held the 7.6V nominal rail under load without sagging to cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install discharge cycle:\u003c\/strong\u003e\n    After fitting this cell, run one full discharge to hibernate cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap on the Envy X2.\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 replacing the Envy X2 cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eWhen you swap the cell, the BIOS still holds EEPROM data from the old battery. That data includes cycle count, wear level, and rated capacity — all tied to the original cell's history. Until the learn cycle runs, the BIOS compares the new cell against stale figures and flags it as degraded. One full discharge-to-hibernate followed by an uninterrupted charge to 100% forces the firmware to re-anchor its reference points to the new cell. After that cycle, the health warning clears and the reported capacity aligns with the 31.92Wh rating.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFuel gauge showing wildly wrong percentage for the first few charges\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe fuel gauge IC on the Envy X2 estimates state of charge by tracking voltage curves it learned from the old cell. A new cell has a different voltage-to-capacity curve until the IC calibrates against it. You'll see jumps — 40% dropping to 10% instantly, or the gauge stalling near full. Run two to three full discharge and charge cycles without interrupting either phase. By the third cycle the IC has enough data points to track the new cell accurately and the percentage readout stabilises.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409761992794,"sku":"BWCS-HPE213NB-1","price":63.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409762025562,"sku":"BWCS-HPE213NB-2","price":74.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409762058330,"sku":"BWCS-HPE213NB-3","price":82.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HPE213NB-1.webp?v=1779580716","url":"https:\/\/batteryweb.com\/products\/hp-envy-x2-13-replacement-battery-76v-4200mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
