It matches the OEM connector, BMS handshake protocol, and voltage rail used across this Envy generation. Fit is confirmed against OEM part numbers HSTNN-UB3H, HSTNN-DB3H, TPN-I104, LR08XL, and 660152-001 among others.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eEnvy 15-3000 through 15-3300 compatibility:\u003c\/strong\u003e\n    These four sub-series share the same 14.8V four-cell architecture, identical board connector, and the same BMS communication protocol — which is why one cell works across all of them without firmware differences.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on an Envy 15-3000 chassis. The BMS handshake completed correctly, charge acceptance reached full rated capacity, and the BIOS recognised the cell without fault flags during our test cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on the Envy 15:\u003c\/strong\u003e\n    After fitting, run one full discharge down to hibernate-cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that routinely appears after any 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\"\u003eWhy the Envy 15 BIOS reports poor battery health after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Envy 15 stores battery health data in EEPROM on the original cell. When you swap in a new cell, that EEPROM data is gone and the BIOS flags the battery as degraded or unknown — even though the new cell is full capacity. This is a data mismatch, not a hardware fault. Running one full discharge-to-hibernate then an uninterrupted charge to 100% lets the BIOS rewrite its learn-cycle data against the new cell. After two to three full cycles, the health indicator normalises.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts off 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 gauge loses track of actual remaining capacity and the laptop hits a voltage cliff — the cell voltage drops below the BMS cutoff threshold before the OS-reported percentage reaches zero. It is not a faulty cell. Run two full discharge-to-hibernate cycles followed by uninterrupted charges to 100% to force the fuel gauge IC to map the new cell correctly. After calibration, shutdowns under load typically stop occurring above 10–12%.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409776705626,"sku":"BWCS-HPE153NB-1","price":129.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409776738394,"sku":"BWCS-HPE153NB-2","price":148.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409776771162,"sku":"BWCS-HPE153NB-3","price":164.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HPE153NB-1.webp?v=1779580839","url":"https:\/\/batteryweb.com\/products\/hp-envy-15-3000-replacement-battery-148v-4850mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
