It replaces OEM part numbers SA04XL, HSTNN-OB1F, HSTNN-UB7U, L43248-541, and related variants. Fit covers the Envy X360 15-DS and 15-DR series convertible notebooks.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e15-DS and 15-DR series compatibility:\u003c\/strong\u003e\n    Both sublines share the same 15.2V four-cell architecture, connector pinout, and BMS handshake protocol — that is why one battery pack covers both chassis revisions 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 15-DS0002NC and confirmed the BMS initialised correctly, charge acceptance reached full capacity, and the EC reported accurate voltage and current across the full charge curve.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install recalibration cycle:\u003c\/strong\u003e\n    After fitting, run the laptop down to hibernate-cutoff on battery only, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that almost always 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\"\u003eBIOS reporting poor battery health immediately after installation\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eHP's embedded controller reads EEPROM data written by the original cell during manufacture. When a new cell goes in, that EEPROM signature does not match the EC's stored learn data, so the system flags health as poor or unknown before any real-world cycles have occurred. This is a firmware state, not a battery fault. One full discharge-to-hibernate followed by an uninterrupted charge to 100% allows the EC to write a new baseline. After that cycle, health status typically corrects itself.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shutting down at 20–30% shown on the fuel gauge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe fuel gauge IC on the 15-DS platform maps state-of-charge using voltage curves calibrated to the original cell's chemistry. A new cell with slightly different internal resistance produces a voltage cliff the uncalibrated gauge misreads as a higher remaining charge than actually exists. Under combined CPU and display load, the cell voltage drops below the EC's cutoff threshold before the gauge hits zero. Run two full discharge-to-hibernate and full charge cycles — this gives the fuel gauge IC enough data points to recalibrate its discharge curve to 15.2V nominal chemistry.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409624203354,"sku":"BWCS-HPE365NB-1","price":93.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409624236122,"sku":"BWCS-HPE365NB-2","price":106.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409624268890,"sku":"BWCS-HPE365NB-3","price":116.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HPE365NB-1.webp?v=1779580296","url":"https:\/\/batteryweb.com\/products\/hp-envy-x360-15-ds0002nc-replacement-battery-152v-3350mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
