It fits the 15-EB0005UR, 15-EB0025TX, 15-EB0035TX, 15-EB0053TX, and related EB0-suffix models. OEM part numbers BN06XL, L68235-1C1, 68299-0055, and HSTNN-IB9A all cross-reference to this cell configuration.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eEB-series platform fit:\u003c\/strong\u003e\n    The 15-EB lineup shares a common battery bay geometry, connector pinout, and BMS handshake protocol across its SKUs. Swapping between EB0-suffix models does not require firmware changes — the SMBus communication lines carry the same charge controller signals across all supported variants.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell on an EB-series unit and monitored the BMS through charge initiation, taper phase, and full-charge cutoff. The cell accepted the charge profile without triggering overcurrent flags and the SMBus reported state-of-charge data correctly from the first cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap calibration on the Spectre X360:\u003c\/strong\u003e\n    After installing, run a full discharge until the laptop hibernates at the low-battery threshold, then charge uninterrupted to 100%. This forces the BIOS battery learn cycle to reset against the new cell's actual capacity and clears the inaccurate health warning that appears after every cell replacement.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Spectre X360 15-EB shuts down at 20–30% charge remaining\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC still holds calibration data from the old, degraded cell. Under full CPU plus display load, the new cell's actual voltage is higher than the old cell's equivalent at that state-of-charge — but the IC reads the percentage against a stale capacity map and triggers shutdown early. Running two or three full discharge-to-hibernate cycles allows the fuel gauge to remap its discharge curve against the new cell's voltage profile. After calibration, shutdowns at inflated percentages stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBIOS reporting battery health as \"poor\" immediately after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe HP BIOS reads health data from the battery's EEPROM, which logs cycle count, charge history, and rated capacity. On a new cell, this EEPROM is either blank or carries factory defaults the BIOS flags as mismatched. The fix is to complete a full battery learn cycle: discharge fully to hibernate cutoff, then charge uninterrupted to 100% without interruption. After one complete cycle, the BIOS re-reads EEPROM and the health warning clears — no firmware update required.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409597300826,"sku":"BWCS-HSX365NB-1","price":97.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409597333594,"sku":"BWCS-HSX365NB-2","price":114.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409597366362,"sku":"BWCS-HSX365NB-3","price":127.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HSX365NB-1.webp?v=1779580129","url":"https:\/\/batteryweb.com\/products\/hp-spectre-x360-15-eb0005ur-replacement-battery-1155v-5900mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
