It fits the full Pavilion PC 15 range, including the 15-AU010WM, 15-AU018WM, and over 200 additional sub-models sharing the BP02XL form factor. OEM part numbers include HSTNN-UB7B, TPN-Q172, TPN-Q175, and 849569-421.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePavilion 15 series compatibility:\u003c\/strong\u003e\n    These models share a unified battery bay dimension, the same 7.7V two-cell Li-Polymer voltage rail, and an identical SMBus BMS handshake. Any sub-model pulling the BP02XL OEM number will seat and communicate correctly with this cell.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell on a Pavilion 15-AU unit and cycled it through charge, full-load discharge, and thermal monitoring. The BMS negotiated correctly with the EC firmware, held stable voltage under CPU and display load, and triggered hibernation-cutoff at the expected threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle reset on Pavilion 15:\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 battery health as poor after installing a new BP02XL\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe HP Pavilion 15 EC reads health data from an EEPROM register carried over from the previous cell. When a new cell arrives with a fresh cycle count, the BIOS compares it against the old register and flags a mismatch as poor health. This is a firmware read error, not a fault with the replacement cell. Run the HP Battery Check utility after completing one full discharge-to-hibernate and uninterrupted charge cycle. Most units clear the warning automatically once the BIOS completes its learn cycle and overwrites the stale EEPROM values.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePavilion 15 shutting down at 20–30% charge shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage cliff symptom, not a calibration issue. Under combined CPU and display load, the cell voltage drops faster than the fuel gauge IC can track, and the laptop hits the EC low-voltage cutoff before the percentage reaches zero. It typically appears when the old cell's EEPROM discharge curve is still loaded into the fuel gauge IC. Run two full discharge-to-hibernate cycles followed by uninterrupted charges to 100%. After the second cycle, the fuel gauge IC recalibrates its discharge model against the new cell chemistry and the early shutdowns stop.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409741840474,"sku":"BWCS-HPC150NB-1","price":57.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409741873242,"sku":"BWCS-HPC150NB-2","price":67.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409741906010,"sku":"BWCS-HPC150NB-3","price":74.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HPC150NB-1.webp?v=1779580582","url":"https:\/\/batteryweb.com\/products\/hp-pavilion-pc-15-replacement-battery-77v-5300mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
