It covers the full range of OEM part numbers under this platform — 372771-001, HSTNN-DB06, HSTNN-LB11, PB992A, and others. If your original battery no longer holds a charge or fails to power the system, this is the direct cell replacement.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e8700 and nw8440 platform compatibility:\u003c\/strong\u003e\n    These models share a common 14.8V power rail, identical connector pinout, and the same BMS handshake protocol — which is why one cell works across 25-plus model variants. The battery pack identifies itself to the BIOS via the same EEPROM signature, so the system accepts it without driver conflicts.\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 an 8510w unit. The BMS engaged cutoff correctly at low voltage, and the BIOS recognised the pack without flagging unknown device status on first boot.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on 8700 series:\u003c\/strong\u003e\n    After fitting this battery, run one full discharge until the laptop hibernates, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that often appears after a 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 battery health as poor immediately after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe HP BIOS on 8700-series machines stores battery health data in EEPROM and compares it against the new cell on first boot. A freshly installed cell has no discharge history, so the BIOS flags it as degraded — not because the cell is faulty, but because the learn cycle hasn't run yet. Complete one full discharge-to-hibernate followed by an uninterrupted charge to 100%. After that cycle, the health status normalises and the warning clears.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down at 20–30% charge shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC is still calibrated to the old, degraded cell and misreads the new cell's actual state of charge. Under full CPU and display load, the 8700 draws enough current to expose the voltage cliff — the real cell voltage drops below the cutoff threshold even though the OS gauge still shows 20–30% remaining. The fix is a calibration cycle: discharge fully to automatic hibernate, then charge to 100% without interruption. After two or three cycles the fuel gauge IC re-maps to the new cell's actual voltage curve and the early shutdowns stop.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410861228122,"sku":"BWCS-NC8200NB-1","price":81.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43410861260890,"sku":"BWCS-NC8200NB-2","price":95.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43410861293658,"sku":"BWCS-NC8200NB-3","price":106.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NC8200NB-1.webp?v=1779581377","url":"https:\/\/batteryweb.com\/products\/hp-business-notebook-8700-replacement-battery-148v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
