It fits the detachable tablet section of the hybrid, restoring unplugged operation when the original cell has degraded. Confirmed fitment includes L8L94PA, L4H91AW, and units carrying OEM part numbers HSTNN-DB5Z, 750549-001, 750549-005, and 750549-006.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eElite x2 G1 tablet unit compatibility:\u003c\/strong\u003e\n    These models share the same 7.4V power rail, flat Li-Polymer form factor, and BMS handshake protocol. The connector pinout and cell dimensions (266.90 × 79.25 × 4.20mm) are identical across the Elite x2 G1 family, so the same cell fits all listed variants.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through full charge and discharge cycles on an Elite x2 1011 G1 unit. The BMS accepted the cell without fault codes, charge current ramped normally through CC\/CV stages, and the protection circuit tripped correctly at the low-voltage cutoff threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBIOS learn cycle after install:\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 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 battery health as poor after swapping the OL02XL cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Elite x2 G1 BIOS reads health data stored in the old cell's EEPROM. When a new cell is installed, the EEPROM contains no charge history, so the BIOS flags it as unknown or degraded. This is a calibration gap, not a fault with the replacement cell. Run one full discharge cycle to hibernate-cutoff followed by an uninterrupted charge to 100%, and the BIOS battery learn routine will write fresh baseline data to the cell's EEPROM, clearing the warning.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eElite x2 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 is still calibrated to the old cell's voltage curve. Under combined CPU and display load, the new cell hits a voltage cliff that the uncalibrated gauge misreads as 20–30% remaining. The system interprets the sudden voltage drop as a critical low and triggers an immediate shutdown. Complete two to three full discharge-to-hibernate then full-charge cycles — by the third cycle the fuel gauge IC recalibrates to the new cell and the shutdowns stop.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409763532890,"sku":"BWCS-HPG101NB-1","price":73.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409763565658,"sku":"BWCS-HPG101NB-2","price":85.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409763598426,"sku":"BWCS-HPG101NB-3","price":94.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HPG101NB-1.webp?v=1779580715","url":"https:\/\/batteryweb.com\/products\/hp-elite-x2-g1-replacement-battery-74v-4450mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
