It fits the same connector and battery bay as the original pack. Voltage and capacity match the OEM spec exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e2100 and 2150 series compatibility:\u003c\/strong\u003e\n    These models share the same 14.4V rail, physical bay dimensions, and connector pinout — that is why one cell crosses all of them. The BMS handshake protocol is identical across the series, so the BIOS reads this pack without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through charge and discharge cycles on a 2100 chassis. The BMS held charge termination correctly at 4.2V per cell, and the protection circuit tripped cleanly on overcurrent — no anomalies logged.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle reset for the 2100 BIOS:\u003c\/strong\u003e\n    After installing, run one full discharge down to hibernate cutoff, then charge uninterrupted to 100% without unplugging early. This lets the BIOS complete its battery learn cycle and clears the inaccurate 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\"\u003eWhy the Averatec 2100 BIOS flags a new battery as poor health\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe BIOS reads health data from EEPROM registers written to the original cell during manufacturing. A replacement cell ships with different EEPROM baseline values, so the health estimate looks wrong on first boot — sometimes showing 0% or \"unknown.\" This is a data mismatch, not a faulty battery. One complete discharge-to-hibernate followed by a full uninterrupted charge resets the learn cycle and re-anchors the health estimate to the new cell's actual capacity.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eAveratec 2100 shutting down suddenly at 20–30% charge shown\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe fuel gauge IC calculates remaining charge based on a model built against the old cell's characteristics. After a swap, that model is stale — the new cell hits a voltage cliff under full CPU and display load before the gauge reaches zero. The laptop interprets the sudden voltage drop as an emergency and cuts power. Two to three full calibration cycles — discharge fully to hibernate, charge to 100% each time — re-train the gauge IC against the new cell. After calibration, the shutdown threshold should align with actual cell voltage near 3.0V per cell.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409815502938,"sku":"BWCS-MSX320NB-1","price":101.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409815535706,"sku":"BWCS-MSX320NB-2","price":116.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409815568474,"sku":"BWCS-MSX320NB-3","price":127.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/batteryweb.com\/products\/averatec-2100-replacement-battery-144v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
