It fits the Pursuit 8880, T2100, NX-8080, and M8080 among others. Voltage and capacity match OEM spec exactly — 14.8V nominal, 65.12Wh total.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePursuit-series platform fit:\u003c\/strong\u003e\n    These Systemax Pursuit models share the same 14.8V four-cell Li-ion architecture, identical connector pinout, and BMS handshake protocol. One battery services the whole family without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and load on the bench. The BMS balanced all four cell groups correctly, held stable voltage under sustained CPU and display load, and tripped thermal cutoff only at the rated threshold — not prematurely.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle recalibration on Pursuit notebooks:\u003c\/strong\u003e\n    After installing, run a full discharge 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 false health warning that appears after every 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 fitting a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Pursuit BIOS reads health status from EEPROM data carried over from the old pack — not from the new cell's actual chemistry. Until you run a full learn cycle, the firmware assumes the replacement is the same degraded cell it just saw. One complete discharge-to-hibernate followed by an uninterrupted full charge writes fresh reference data into the EEPROM. After that cycle, the health indicator updates to reflect the actual state of the new cell.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePursuit 8880 shutting down abruptly at 20–30% charge shown\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage cliff, not a capacity problem. Under combined CPU and display load, the cell voltage drops faster than the fuel gauge IC can track — the system hits the low-voltage cutoff before the displayed percentage reaches zero. It happens most on cells that have never been calibrated to this platform. Run two full discharge-to-hibernate cycles to let the fuel gauge IC map the voltage curve against real load. After calibration, the shutdown threshold and the displayed percentage should align at or below 5%.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410829934682,"sku":"BWCS-MT8080NB-1","price":71.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43410829967450,"sku":"BWCS-MT8080NB-2","price":83.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43410830000218,"sku":"BWCS-MT8080NB-3","price":93.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MT8080NB-big.webp?v=1779581286","url":"https:\/\/batteryweb.com\/products\/mitac-systemax-pursuit-8880-replacement-battery-148v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
