It replaces OEM part numbers PC03XL, HSTNN-OB1W, M24421-271, M24648-005, and TPN-DB0E. Fit it when the original cells can no longer hold a charge across a normal workday.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePavilion Aero 13-be and x360 crossover fit:\u003c\/strong\u003e\n    These Pavilion lines share the same three-cell Li-Polymer platform, 11.55V power rail, and PC03XL BMS handshake. One pack covers the Aero 13-be, x360 Convertible 14-dy, and x360 15-er because HP used the same battery bay geometry and connector pinout across all three chassis refreshes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through charge and discharge on a Pavilion Aero 13-be unit. The BMS negotiated correctly with the EC firmware, cell balancing triggered at the expected threshold, and the pack reached full capacity without thermal events or charge interruptions.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install discharge cycle on Pavilion Aero:\u003c\/strong\u003e\n    After fitting this pack, let the laptop discharge fully until it hibernates — do not interrupt it. Then charge uninterrupted to 100%. This single full cycle resets the BIOS battery-learn register and clears the inaccurate \"Consider replacing your battery\" health warning that 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 Pavilion Aero shuts down between 20–30% after a battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Pavilion Aero's EC pulls voltage readings from the battery's fuel gauge IC, not a direct cell measurement. When a new cell goes in, the fuel gauge IC still holds calibration data from the old, degraded pack. Under peak CPU plus display load, the new cell's actual voltage briefly drops below the threshold the EC expects at that state-of-charge, triggering an emergency shutdown. The fix is one full discharge-to-hibernate cycle followed by a full uninterrupted charge. After two or three full cycles, the fuel gauge IC recalibrates against the new cell's actual discharge curve and the premature shutdowns stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBIOS showing wrong Wh rating or \"Unknown Battery\" after fitting PC03XL\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe HP BIOS reads Wh rating and battery identity from the pack's EEPROM data table, not from live cell measurements. The PC03XL EEPROM is programmed to the OEM 42.16Wh spec, so if your BIOS previously stored data from a third-party or partially failed cell, it may display a mismatch or \"Unknown\" status on first boot. Go into BIOS Setup (F10 at POST), navigate to the battery information screen, save and exit — this forces the EC to re-read the new EEPROM. If the system still shows incorrect Wh after that step, update HP's firmware via HP Support Assistant, then repeat the full discharge-to-hibernate cycle to 100%.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409645273178,"sku":"BWCS-HPA130NB-1","price":63.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409645305946,"sku":"BWCS-HPA130NB-2","price":75.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409645338714,"sku":"BWCS-HPA130NB-3","price":83.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HPA130NB-1.webp?v=1779580060","url":"https:\/\/batteryweb.com\/products\/hp-pavilion-aero-13-be0141au-replacement-battery-1155v-3650mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
