It fits the TPN-Q146, TPN-Q147, TPN-Q148, and TPN-Q149 board revisions, along with the Pavilion X360 13-A010DX and the broader Pavilion X360 range. OEM cross-references include HSTNN-LB6L, 760944-421, 761230-005, and 767068-005.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePavilion X360 TPN-Q146 through TPN-Q149 compatibility:\u003c\/strong\u003e\n    These four board variants share the same 11.4V three-cell lithium-polymer rail, connector pinout, and BMS handshake protocol — which is why a single cell replaces all of them without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell on a TPN-Q147 unit. The BMS completed charge acceptance without flagging a fault, voltage held steady under combined CPU and display load, and the fuel gauge IC registered cell capacity within one calibration cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation discharge cycle on the X360:\u003c\/strong\u003e\n    After fitting this cell, run the laptop on battery until it hibernates at low charge, then charge uninterrupted to 100%. This forces the BIOS battery learn cycle to reset against the new cell 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 poor battery health immediately after fitting the NP03XL\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe HP BIOS stores learned capacity data from the previous cell in a battery learn table. When a new cell goes in, that table still reflects the old, degraded values — so the system flags the health as poor before it has measured the new cell at all. This is not a fault with the replacement. The BIOS needs one full discharge-to-hibernate followed by an uninterrupted charge to 100% to rewrite the learn table against the new chemistry. After that cycle, the health indicator should return to normal.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePavilion X360 shutting down at 20–30% charge shown on screen\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 voltage curve. The gauge maps a voltage reading to a percentage based on old cell data, so it under-reports remaining charge — and the laptop hits its low-voltage cutoff while the screen still shows 20–30%. The fix is to complete two or three full discharge-and-charge cycles without interruption. After calibration, the cutoff aligns with the displayed percentage, and the laptop should reach the screen-off hibernate point below 5%.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409773822042,"sku":"BWCS-HPX361NB-1","price":63.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409773854810,"sku":"BWCS-HPX361NB-2","price":74.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409773887578,"sku":"BWCS-HPX361NB-3","price":82.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HPX361NB-1.webp?v=1779580839","url":"https:\/\/batteryweb.com\/products\/hp-pavilion-x360-replacement-battery-114v-3750mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
