It fits the Spectre 13-3000, Spectre 13t-3000, Spectre 13-3000EA Ultrabook, and TPN-F111 variants. OEM cross-references include HSTNN-LB5Q, 734746-421, and 734998-001.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSpectre 13-3000 platform compatibility:\u003c\/strong\u003e\n    All Spectre 13-3000 and 13t-3000 variants share the same 7.5V connector pinout and BMS handshake protocol. The RG04XL form factor — 308.30 × 131.48 × 4.34 mm — fits the ultrabook chassis without modification.\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 a Spectre 13-3000 unit. The BMS accepted the cell, reported voltage correctly, and thermal cutoff triggered at expected thresholds under sustained CPU and display load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on the Spectre 13-3000:\u003c\/strong\u003e\n    After installing, 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 poor battery health immediately after fitting the RG04XL\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen you swap the physical cell, the BIOS still holds EEPROM data from the old battery. That data includes cycle count, calibration baselines, and health flags — all tied to the previous cell's history. The new cell has no matching EEPROM record, so the BIOS flags it as degraded or unknown. Running the battery learn cycle — full discharge to hibernate-cutoff followed by an uninterrupted charge to 100% — overwrites the stale EEPROM values and lets the fuel gauge IC calibrate against the new cell's actual chemistry.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSpectre 13-3000 shutting down abruptly at 20–30% charge shown\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage cliff issue, not a capacity issue. Under combined CPU boost and full display brightness, the cell must sustain voltage above the BMS cutoff threshold. If the fuel gauge IC hasn't completed calibration cycles against the new cell, it misreads the remaining charge and the laptop shuts down before the displayed percentage reaches zero. Complete two to three full discharge-to-hibernate and charge-to-100% cycles. After calibration, the gauge tracks the actual voltage curve and shutdowns at low-charge states stop. Target resting voltage at full charge should read 8.4V at the connector.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409771233370,"sku":"BWCS-HPN111NB-1","price":118.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409771266138,"sku":"BWCS-HPN111NB-2","price":136.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409771298906,"sku":"BWCS-HPN111NB-3","price":149.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HPN111NB-1.webp?v=1779580789","url":"https:\/\/batteryweb.com\/products\/hp-spectre-13-3000-replacement-battery-75v-6750mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
