It fits the gaze14 chassis directly, using OEM part numbers 6-87-NH50S-41C00 and NH50BAT-4. If your original cell no longer holds a charge or swells, this replaces it without modification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003egaze14 platform fit:\u003c\/strong\u003e\n    The Gazelle gaze14 uses a four-cell Li-ion pack at 14.4V with a specific BMS handshake tied to those OEM part numbers. Both 6-87-NH50S-41C00 and NH50BAT-4 reference the same pack configuration — same connector pinout, same voltage rail, same BMS communication protocol.\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 the gaze14 platform. The BMS handshake completed cleanly, charge termination triggered at the correct cutoff voltage, and the pack delivered its rated capacity without thermal event or early cutoff under CPU and display load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap calibration cycle:\u003c\/strong\u003e\n    After fitting this battery, run the laptop down to hibernate cutoff under normal workload — do not force-shutdown — then charge uninterrupted to 100%. This forces the BIOS battery learn cycle to reset against the new cell 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 battery health as poor after replacement on the gaze14\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe gaze14 BIOS reads health data stored in the battery pack's EEPROM and compares it against a learned baseline from the previous cell. When a new cell goes in, that baseline is gone — the BIOS flags poor health because the EEPROM data no longer matches what it expects. This is not a fault with the replacement cell. Running a full discharge-to-hibernate followed by an uninterrupted charge to 100% forces the firmware to rewrite its learned cycle data against the new cell chemistry. After one or two complete cycles, the health indicator updates and the warning clears.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eGazelle gaze14 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 loses calibration — its capacity model no longer maps accurately to the actual voltage curve of the cell it's reading. The laptop's power manager triggers shutdown based on a predicted voltage floor that no longer matches reality, so it cuts out well before the cell is truly depleted. The fix is a calibration cycle: let the battery drain fully to hibernate cutoff under a real workload with screen at normal brightness, then charge without interruption to 100%. Repeat this once more if the gauge is still off — two full cycles are usually enough to realign the IC's model to the new cell's actual 14.4V discharge curve.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409594089562,"sku":"BWCS-CLH580NB-1","price":65.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409594122330,"sku":"BWCS-CLH580NB-2","price":77.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409594155098,"sku":"BWCS-CLH580NB-3","price":86.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CLH580NB-1.webp?v=1779580129","url":"https:\/\/batteryweb.com\/products\/systemax-system76-gazellegaze14-replacement-battery-144v-2200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
