It covers a wide range of configurations across that lineup, including the L5G44EA, L5G75EA, and 4G variants. Cross-references include 750335-2B1, 750550-001, HSTNN-DB6A, and HSTNN-I22X.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eElite x2 1011 G1 series compatibility:\u003c\/strong\u003e\n    These models share a common voltage rail, connector pinout, and BMS handshake protocol across the G1 generation. The same cell chemistry and EEPROM structure applies to all covered variants, so the BMS negotiation completes without error flags on any of them.\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 the Elite x2 1011 platform. The BMS completed handshake, charge current ramped correctly through CC\/CV stages, and the fuel gauge IC registered the new cell without triggering an unknown battery warning.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install recalibration tip for the Elite x2:\u003c\/strong\u003e\n    After fitting this cell, run one full discharge down to hibernate cutoff, then charge uninterrupted to 100%. The Elite x2 BIOS uses a battery learn cycle — skipping this leaves the fuel gauge reading from stale EEPROM data, which causes the \"poor health\" warning to persist even with a new cell installed.\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 replacing the cell in the Elite x2 1011\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe HP Elite x2 1011 BIOS stores battery health data in EEPROM and does not automatically clear it when a new cell is installed. On first boot with a replacement cell, the BIOS reads the old degradation values and flags the battery as unhealthy. This is not a fault with the new cell — it is a data mismatch between the EEPROM record and the actual cell state. Running a full discharge-to-hibernate followed by an uninterrupted full charge forces the learn cycle to overwrite the stale EEPROM data.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down at 20–30% charge shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the cell voltage drops sharply under combined CPU and display load before the fuel gauge registers 0%. The Elite x2 is a thin platform with no thermal buffer, so high-draw moments — display at full brightness, active CPU task — pull current the fuel gauge IC has not yet mapped to the new cell's discharge curve. The BIOS interprets the voltage cliff as an imminent cutoff and shuts down as a protection measure. After two or three full calibration cycles, the fuel gauge IC builds an accurate model of the new cell and the premature shutdowns stop. Target cell voltage at cutoff is approximately 6.0V under load for this 7.4V nominal pack.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409656184922,"sku":"BWCS-HPX201NB-1","price":95.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409656217690,"sku":"BWCS-HPX201NB-2","price":109.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409656250458,"sku":"BWCS-HPX201NB-3","price":120.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HPX201NB-1.webp?v=1779580296","url":"https:\/\/batteryweb.com\/products\/hp-ultrabook-l5g46ea-replacement-battery-74v-2700mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
