It fits the 85H83PA, 819A0EA, 81A52EA, 818W2EA, and related Dragonfly G4 variants. OEM cross-references include SS06XL, M64310-271, M73476-005, and TPN-DB0O.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDragonfly G4 platform fit:\u003c\/strong\u003e\n    These Dragonfly G4 models share the same 11.58V three-cell Li-Polymer architecture, connector pinout, and BMS handshake protocol. The SS06XL designation covers the full G4 refresh line — swapping between listed models 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 through charge and discharge cycles on a Dragonfly G4 unit. The BMS accepted the new cell without error, negotiated full charge capacity, and the BIOS fuel gauge updated correctly after a learn cycle. No charge rejection or protection-circuit trip occurred.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on the Dragonfly G4:\u003c\/strong\u003e\n    After fitting this battery, run one full discharge to hibernate cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears in HP Support Assistant after a cell swap.\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 replacement\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe HP Dragonfly G4 BIOS reads health data from EEPROM embedded in the battery pack, not from live cell voltage alone. When a new cell is installed, the EEPROM profile does not match the BIOS's stored charge history, so it flags the battery as degraded or unknown. This is not a fault with the replacement cell. One full discharge-to-hibernate followed by an uninterrupted charge to 100% allows the BIOS to re-learn the cell's actual capacity curve and clear the warning.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDragonfly G4 shutting down at 20–30% charge shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis symptom appears when the fuel gauge IC has not yet calibrated against the new cell's voltage-to-capacity curve. The OS reads a voltage that maps to 20–30% on the old cell's profile, but the new cell hits a voltage cliff at that point under combined CPU and display load. The laptop cuts power before the gauge reaches zero. To fix it, complete two to three full discharge-to-hibernate and charge-to-100% cycles so the fuel gauge IC recalibrates. After calibration, shutdowns at that percentage should stop.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409552015450,"sku":"BWCS-HPG485NB-1","price":88.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409552048218,"sku":"BWCS-HPG485NB-2","price":104.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409552080986,"sku":"BWCS-HPG485NB-3","price":115.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HPG485NB-1.webp?v=1779580013","url":"https:\/\/batteryweb.com\/products\/hp-dragonfly-g4-85h83pa-replacement-battery-1158v-5800mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
