It fits all G2 variants including 1GY29PA, 1GY30PA, and 1GY31PA. It cross-references OEM part numbers OM03XL, HSTNN-IB70, 863167-171, and 863280-855, among others.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eEliteBook x360 1030 G2 fit group:\u003c\/strong\u003e\n    All variants in the G2 series share the same connector pinout, cell voltage rail, and BMS handshake protocol. The x360 hinge assembly requires the flat 4.90mm profile — this cell matches those physical and electrical specs exactly.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell on the 1030 G2 platform and confirmed BMS handshake, charge acceptance from the HP Smart AC adapter, and stable discharge under sustained CPU and display load. The protection circuit tripped correctly at low-cell-voltage threshold with no unexpected cutoffs during normal operation.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on the x360 1030 G2:\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 in HP Support Assistant after every cell swap.\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 immediately after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe HP EliteBook BIOS reads EEPROM data embedded in the battery controller to assess health. When a new cell arrives, that EEPROM has not yet been calibrated against the laptop's charge history, so the BIOS flags it as degraded or unknown. This is not a cell fault — it is a data mismatch. Run a full discharge-to-hibernate followed by a complete uninterrupted charge to 100%, and the BIOS learn cycle will rewrite the health status against the new cell's actual capacity 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 fuel gauge IC has not yet calibrated against the new cell's discharge curve. The percentage shown is based on old cell data — when actual cell voltage drops under combined CPU, display, and hinge-sensor load, the BMS cuts out before the gauge catches up. The fix is two to three full calibration cycles: discharge to auto-hibernate, then charge to 100% each time. After those cycles the fuel gauge IC maps the new cell's voltage curve correctly and the early shutdowns stop.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409736663130,"sku":"BWCS-HPE360NB-1","price":109.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409736695898,"sku":"BWCS-HPE360NB-2","price":123.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409736728666,"sku":"BWCS-HPE360NB-3","price":135.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HPE360NB-1.webp?v=1779580582","url":"https:\/\/batteryweb.com\/products\/hp-elitebook-x360-1030-g2-replacement-battery-1155v-4900mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
