It matches the original LP03XL specification — same voltage rail, same connector pinout, same BMS communication protocol. Fits 264+ Envy 15 models sharing this battery platform.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eEnvy 15 AE-series platform fit:\u003c\/strong\u003e\n    These models share a common 11.4V three-cell architecture with a standardised BMS handshake and identical dock connector. Any deviation in voltage rail or BMS protocol would cause an immediate \"consider replacing your battery\" flag in Windows — this cell avoids that by matching the original LP03XL specification exactly.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this battery through charge and discharge cycles on an Envy 15 unit. The BMS reported cell recognised status, charge current ramped correctly through CC\/CV phases, and no protection faults triggered at either end of the charge curve.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle calibration on the Envy 15:\u003c\/strong\u003e\n    After fitting, discharge the laptop to hibernate cutoff under normal use — screen on, applications running — 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\"\u003eWhy the Envy 15 shuts down at 20–30% remaining after a battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Envy 15 BIOS stores a discharge curve mapped to the original cell's impedance profile. When a new cell is installed, that stored curve no longer matches actual cell behaviour. Under combined CPU and display load, voltage drops faster than the BIOS predicts — it interprets this as a dangerously low state and forces shutdown, even when the fuel gauge still shows charge remaining. Running one full discharge-to-hibernate cycle followed by an uninterrupted full charge gives the BIOS enough data to remap its cutoff thresholds to the new cell. After two to three of these cycles, the shutdowns stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBIOS reporting \"0% available (plugged in, charging)\" after installation\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the EEPROM data from the old, deeply discharged cell is still cached — the system reads the remnant state-of-charge register as zero and won't update until the new cell's voltage rises above the detection threshold, typically around 10.8V. If the replacement cell shipped at a low state of charge, the BIOS may not register it at all on first boot. Plug in the AC adapter and leave the laptop off for 15–20 minutes before powering on — this allows the charge controller to pre-charge the cell past the recognition threshold. Once Windows sees the battery above 10.8V, the fuel gauge initialises correctly and the 0% reading clears.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410735595610,"sku":"BWCS-HPE158NB-1","price":70.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43410735628378,"sku":"BWCS-HPE158NB-2","price":82.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43410735661146,"sku":"BWCS-HPE158NB-3","price":91.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HPE158NB-1.webp?v=1779580582","url":"https:\/\/batteryweb.com\/products\/hp-envy-15-ae015tx-replacement-battery-114v-4650mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
