It fits a wide range of ZBook Studio G7 configurations, including the 2J3H8PA, 1J3R6EA, 1J3U6EA, and 21X54UT, among others. OEM part numbers covered include MB06XL, HSTNN-IB9E, L77973-1C1, and L78553-005.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eZBook Studio G7 platform fit:\u003c\/strong\u003e\n    All listed G7 configurations share the same 11.58V three-cell Li-Polymer architecture, the same physical connector pinout, and the same BMS handshake protocol. That is why one SKU covers the full model range — the power rail and communication lines are identical across these variants.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through a full charge and discharge cycle on a ZBook Studio G7 chassis. The BMS negotiated correctly with the EC, charge current stepped down normally at top-of-charge, and the protection circuit tripped cleanly at the low-voltage cutoff threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eZBook Studio G7 first-cycle reset:\u003c\/strong\u003e\n    After installing this cell, run one full discharge down to hibernate-cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears on the first boot after any 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 battery health as poor immediately after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe ZBook Studio G7 BIOS reads health data from EEPROM registers on the battery's fuel gauge IC, not from a live capacity measurement. When a new cell is installed, those registers still reflect the degraded profile of the old battery until a learn cycle writes fresh data. This is not a fault with the replacement cell — it is a calibration state. Run a full discharge to hibernate-cutoff followed by an uninterrupted charge to 100% to force the BIOS to rewrite the health registers. After one complete cycle, the health status should return to normal.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop 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 reported state-of-charge diverges from real cell voltage under load — the workstation hits the hardware low-voltage cutoff while the OS still shows charge remaining. Under full CPU and display load, the G7 draws enough current to expose this gap quickly. Two to three full discharge-and-charge cycles recalibrate the fuel gauge IC; the shutdowns stop once the reported percentage aligns with the actual cell voltage at load, typically above 3.4V per cell at cutoff.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409604477018,"sku":"BWCS-HPG721NB-1","price":96.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409604509786,"sku":"BWCS-HPG721NB-2","price":112.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409604542554,"sku":"BWCS-HPG721NB-3","price":125.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HPG721NB-1.webp?v=1779580172","url":"https:\/\/batteryweb.com\/products\/hp-zbook-studio-g7-2j3h8pa-replacement-battery-1158v-7050mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
