It matches the original voltage rail, physical footprint (268.10 × 125.70 × 4.00mm), and connector to the motherboard. Also cross-references as HSTNN-LB7L, 901308-421, 901345-855, and CN03057XL.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSpectre X360 13-AB and 13T-AB platform fit:\u003c\/strong\u003e\n    These models share the same 11.55V three-cell Li-Polymer architecture, the same BMS handshake protocol, and the same flat-cable connector. One cell works across the full variant range because HP held that power rail constant through the AB and T-AB board revisions.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell on a Spectre X360 13-AB001 board. The BMS initialised without error, charge current accepted at the full rate, and the BIOS recognised the cell without a firmware prompt. No charge-limit or authentication fault was triggered during the test cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on the Spectre X360:\u003c\/strong\u003e\n    After fitting, run the laptop down to hibernate cutoff under normal load — do not force-shutdown — then charge uninterrupted to 100%. This gives the fuel gauge IC one clean reference cycle against the new cell 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\"\u003eWhy the Spectre X360 shuts down at 20–30% charge shown\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Spectre X360 runs an Intel processor and a high-resolution touch display simultaneously. Under that combined load, the battery voltage drops faster than the fuel gauge predicts — especially with a new cell the gauge IC has never seen before. When cell voltage hits the low-voltage cutoff threshold, the BMS disconnects the pack and the laptop shuts down, even though the OS still shows 20–30% remaining. This is a calibration gap, not a faulty cell. Run two full discharge-to-hibernate then uninterrupted charge cycles, and the gauge IC recalibrates its discharge curve to match the actual cell chemistry.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBIOS reporting the replacement cell as poor health or unknown immediately after install\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe HP BIOS reads battery health from EEPROM data written by the previous cell over its charge history. When a new cell goes in, that EEPROM record is either absent or mismatched, so the BIOS flags the battery as degraded or unknown — before the cell has been used once. This is not a fault with the replacement. To reset it, complete the one full discharge-to-hibernate cycle described above, then charge to 100% without interruption. After that cycle completes, recheck HP Support Assistant — the health status should update to normal.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409723162714,"sku":"BWCS-HPX313NB-1","price":110.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409723195482,"sku":"BWCS-HPX313NB-2","price":125.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409723228250,"sku":"BWCS-HPX313NB-3","price":137.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HPX313NB-1.webp?v=1779580558","url":"https:\/\/batteryweb.com\/products\/hp-spectre-x360-13-ab001-replacement-battery-1155v-4900mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
