It fits the original TF03XL battery slot and restores portable operation when the factory cell no longer holds a charge. OEM part numbers TF03XL, HSTNN-LB7X, HSTNN-UB7J, and 920046-421 all cross to this cell.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePavilion 15-CC and 15-CD compatibility:\u003c\/strong\u003e\n    Both series run the same 11.55V three-cell architecture with an identical connector and BMS handshake over SMBus. The fuel gauge IC communicates directly with the HP BIOS, so the replacement cell must match the original voltage rail — this one does.\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 a Pavilion 15-CC unit. The BMS accepted the charge profile without fault, SMBus communication registered correctly, and the BIOS pulled valid capacity data from the cell's EEPROM.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on the Pavilion 15-CC:\u003c\/strong\u003e\n    After fitting this battery, run one full discharge until the laptop hibernates, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap — skipping this step leaves the fuel gauge IC working against stale EEPROM data from the old cell.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Pavilion 15-CC BIOS flags a new battery as poor health\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eHP's BIOS stores battery health data from the previous cell in a learn table. When a new cell is installed, the BIOS compares live readings against that stored baseline and flags a mismatch as degraded health. This is not a fault with the replacement cell — it is a calibration gap. Running one complete discharge-to-hibernate and full recharge cycle forces the BIOS to rebuild its learn table against the new cell's actual capacity curve. After that cycle, the health indicator in HP Support Assistant updates to reflect the real state of the new battery.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePavilion 15-CC shutting down at 20–30% charge shown\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis shutdown happens when the fuel gauge IC has not yet calibrated against the new cell and misjudges the voltage cliff. Under combined CPU and display load, actual cell voltage drops faster than the uncalibrated gauge predicts — the BIOS triggers an emergency shutdown before the displayed percentage reaches zero. The fix is the same calibration cycle: discharge fully to hibernate cutoff, then charge to 100% without interruption. After two to three cycles the gauge tracks the new cell accurately and the premature shutdowns stop.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409722179674,"sku":"BWCS-HPC155NB-1","price":62.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409722212442,"sku":"BWCS-HPC155NB-2","price":73.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409722245210,"sku":"BWCS-HPC155NB-3","price":81.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HPC155NB-1.webp?v=1779580500","url":"https:\/\/batteryweb.com\/products\/hp-pavilion-15-cc-replacement-battery-1155v-3600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
