It fits the Stream 11-R010NR, Stream 11-R050SA, Stream 11-R000NG, and over 48 other Stream 11 variants. OEM part numbers include PS03XL, HSTNN-DB6R, and 787520-005.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eStream 11 platform fit:\u003c\/strong\u003e\n    All Stream 11 variants on this list share the same 11.4V three-cell Li-Polymer architecture, identical connector pinout, and the same BMS handshake protocol. Swapping within this family does not require firmware changes or hardware 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 Stream 11-R010NR unit. The BMS completed the handshake, charge current stepped correctly through CC and CV phases, and the protection circuit triggered cleanly at the low-voltage cutoff threshold without nuisance trips.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on the Stream 11:\u003c\/strong\u003e\n    After fitting this battery, let the laptop discharge fully until it hibernates on its own — do not force a shutdown. Then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the false \"poor 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\"\u003eWhy the Stream 11 shuts down at 20–30% after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Stream 11's BIOS fuel gauge IC builds a discharge curve against the old cell over hundreds of cycles. When a new cell goes in, that stored curve no longer matches the actual voltage profile of the fresh chemistry. Under combined CPU and display load, the system hits a voltage point it interprets as near-empty — even though the cell has charge remaining. Running two or three full discharge-to-hibernate and uninterrupted-charge cycles forces the fuel gauge IC to recalibrate against the new cell's actual curve. After calibration, the cutoff point tracks accurately again.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBIOS reporting battery Wh as incorrect after fitting a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Wh value shown in BIOS comes from EEPROM data embedded in the battery's communication circuit — not from a live measurement of the cell. Some Stream 11 replacement cells carry EEPROM values written at manufacture that differ slightly from the actual chemistry rating. If BIOS shows a Wh figure that does not match the 42.18Wh spec on this listing, that is an EEPROM read, not a cell fault. The cell's actual charge capacity is unaffected. Confirm the discrepancy by checking the rated label on the battery directly and cross-referencing against the 42.18Wh figure in the product data.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409746591834,"sku":"BWCS-HPS003NB-1","price":109.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409746624602,"sku":"BWCS-HPS003NB-2","price":123.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409746657370,"sku":"BWCS-HPS003NB-3","price":135.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HPS003NB-1.webp?v=1779580648","url":"https:\/\/batteryweb.com\/products\/hp-stream-11-replacement-battery-114v-3700mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
