It fits the Pavilion 14-AL000 and over 230 related 14-inch Pavilion models including the AL001ng, AL003ng, and AL004ng. OEM cross-references include SE03XL, HSTNN-LB7G, HSTNN-UB6Z, and TPN-Q171.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePavilion 14-AL series compatibility:\u003c\/strong\u003e\n    These models share the same three-cell 11.55V battery architecture, identical connector pinout, and the same BMS handshake protocol — which is why one battery covers the full AL000 range despite minor regional hardware variations.\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 14-AL unit. The BMS completed full charge termination cleanly, voltage held stable across the draw curve, and the BIOS battery status reported without fault flags after the initial learn cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on the Pavilion 14-AL:\u003c\/strong\u003e\n    After fitting this cell, run the laptop down to automatic hibernate under normal use — do not force shutdown — then charge it uninterrupted to 100%. This completes 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 immediately after fitting the SE03XL\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Pavilion 14-AL stores learned capacity data in BIOS-managed EEPROM tied to the old cell. When a new cell goes in, that stored data no longer matches the actual charge curve, so the BIOS flags the battery as degraded or unknown. This is a firmware calibration state, not a fault with the replacement cell. One full discharge-to-hibernate followed by an uninterrupted charge to 100% forces the BIOS to rewrite its learned values against the new cell. After two or three cycles the health status will update correctly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down at 20–30% charge shown on the Pavilion 14-AL\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 actual discharge curve. The OS reads a voltage level that looks like 20–30% remaining, but the cell hits its minimum voltage cliff under combined CPU and display load before the gauge catches up. The fix is the same calibration cycle — discharge fully to hibernate cutoff, then charge uninterrupted to 100%. After two full cycles, the fuel gauge IC realigns its reference points and the shutdowns stop. If the problem persists past three cycles, check BIOS battery health at startup — the cutoff voltage floor should sit at 10.8V minimum.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409740922970,"sku":"BWCS-HPE141NB-1","price":63.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409740955738,"sku":"BWCS-HPE141NB-2","price":74.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409740988506,"sku":"BWCS-HPE141NB-3","price":82.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HPE141NB-1.webp?v=1779580582","url":"https:\/\/batteryweb.com\/products\/hp-pavilion-14-al000-replacement-battery-1155v-3500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
