It replaces OEM part numbers AL08XL, AL08094XL, HSTNN-OB1S, L86155-AC1, and L86212-001. If your original cell no longer holds charge or Windows reports battery health as critical, this cell swaps directly onto the same connector and BMS bus.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eZBook Fury 15 G7 and G8 compatibility:\u003c\/strong\u003e\n    Both generations share the same 15.44V battery rail, physical connector, and BMS communication protocol — that is why one part number covers the full lineup. The fuel gauge IC talks the same EEPROM-level handshake on both boards.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through full charge and discharge cycles on a ZBook Fury 15 G8. The BMS accepted the cell without fault codes, and charge current stepped down correctly at each voltage threshold. No capacity mismatch or thermal flag was logged.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle calibration on ZBook Fury 15:\u003c\/strong\u003e\n    After installing, run one full discharge down to hibernate cutoff, then charge uninterrupted to 100%. This forces the BIOS battery learn cycle to reset against the new cell data 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 installation on ZBook Fury 15\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe ZBook Fury 15 BIOS reads health data stored in the old cell's EEPROM and compares it against the new cell's reported state. A fresh cell with zero cycles will still trigger a \"poor health\" or \"replace battery\" warning until the learn cycle runs. This is a firmware calibration gap, not a cell defect. Run one full discharge to hibernate cutoff, then charge to 100% without interruption — the BIOS resets the learned capacity register and the warning clears.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eZBook Fury 15 shutting down abruptly at 20–30% charge shown\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eUnder full CPU and display load, the ZBook Fury 15 draws hard against the battery's voltage floor. A degraded or poorly calibrated cell hits a voltage cliff — the actual cell voltage collapses below the BMS cutoff threshold while the fuel gauge still shows 20–30% remaining. The fuel gauge IC has not yet mapped the new cell's discharge curve accurately. Run two or three complete discharge-to-hibernate and full-recharge cycles to let the gauge IC recalibrate; after that the reported percentage and actual cutoff voltage will align, and the unexpected shutdowns stop.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409517445210,"sku":"BWCS-HPF158NB-1","price":81.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409517477978,"sku":"BWCS-HPF158NB-2","price":95.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409517510746,"sku":"BWCS-HPF158NB-3","price":106.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HPF158NB_1.webp?v=1779579852","url":"https:\/\/batteryweb.com\/products\/hp-zbook-fury-15-g7-replacement-battery-1544v-5900mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
