It fits the ENVY 14-3001TU, 14-3002TU, 14-3003TU, 14-3004TU, and over 40 additional ENVY 14 variants sharing the SL04XL platform. The OEM part numbers covered include SL04XL, 665054-171, TPN-Q105, and HSTNN-IB3J.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eENVY 14 Spectre platform fit:\u003c\/strong\u003e\n    These models share a four-cell Li-Polymer pack at 14.8V nominal with a common BMS handshake and identical 290.14 × 114.25 × 7.08mm footprint. Any variant in the ENVY 14-3000 lineup that originally shipped with SL04XL pulls from the same voltage rail and connector spec.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell on an ENVY 14 Spectre chassis and confirmed BMS communication with the BIOS — the charge controller accepted the new cell, reported pack voltage correctly, and held a steady taper charge to 4.2V per cell without cutoff errors.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle recalibration on ENVY 14:\u003c\/strong\u003e\n    After installing, discharge the laptop fully to hibernate cutoff under normal load — don't force it. Then charge uninterrupted to 100% without using the machine. This single cycle resets the BIOS battery learn cycle and clears the false \"poor health\" or \"replace battery\" warning that almost always appears after a 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 SL04XL\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe ENVY 14 BIOS reads health data from EEPROM registers stored in the old battery pack — not from the new cell's actual charge state. When a new cell is installed, those registers are blank or mismatched, so the BIOS flags the battery as degraded before it has run a single cycle. This is not a fault with the replacement cell. Running one full discharge-to-hibernate followed by an uninterrupted charge to 100% forces the fuel gauge IC to write fresh calibration data. After that cycle, BIOS health reporting normalises.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts off at 20–30% remaining 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 actual voltage curve. The displayed percentage is based on stale data — the cell hits a voltage cliff under combined CPU and display load before the gauge catches up. It is not a defective battery. Run two full discharge-to-hibernate cycles followed by full uninterrupted charges, and the gauge IC will map the correct cut-off point. After calibration, the laptop should sustain load down to approximately 11.1V pack voltage before shutdown.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409787945050,"sku":"BWCS-HPY140NB-1","price":122.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409787977818,"sku":"BWCS-HPY140NB-2","price":140.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409788010586,"sku":"BWCS-HPY140NB-3","price":153.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HPY140NB-1.webp?v=1779580887","url":"https:\/\/batteryweb.com\/products\/hp-envy-14-3001tu-replacement-battery-148v-3900mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
