It fits the MD6032 platform and covers the full OEM part number range including 21-91081-00, 21-91082-00, 21-91083-00, and related variants. Voltage, connector, and BMS handshake match the original specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMD6032 platform fit:\u003c\/strong\u003e\n    All listed OEM part numbers share the same 14.8V rail, physical connector, and BMS communication protocol used across this notebook series. Swapping between these part numbers does not require firmware changes or adapter hardware.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full charge and discharge on the MD6032 platform. The BMS negotiated correctly with the system board, charge current ramped normally, and the cell reached rated capacity without triggering protection cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on the MD6032:\u003c\/strong\u003e\n    After fitting 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 the system logs 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 battery health as poor after fitting the new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe MD6032 BIOS stores historical charge data in EEPROM on the battery controller. When a new cell is installed, that data does not match the new cell's charge curve, so the system flags poor health immediately. This is a data mismatch, not a cell fault. Run the full discharge-to-hibernate then uninterrupted charge cycle once, and the BIOS will update its stored learn data against the new chemistry.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMD6032 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 gauge reports 20–30% remaining, but the cell voltage has already dropped below the load threshold under combined CPU and display draw. The system cuts power to protect the cell before the gauge catches up. Complete two full discharge-to-hibernate and full-charge cycles — after that the gauge IC aligns with the real voltage floor and the early shutdown stops.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410825248858,"sku":"BWCS-ADA440NB-1","price":82.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43410825281626,"sku":"BWCS-ADA440NB-2","price":97.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43410825314394,"sku":"BWCS-ADA440NB-3","price":107.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ADA440NB-1.webp?v=1779581286","url":"https:\/\/batteryweb.com\/products\/microstar-md6032-replacement-battery-148v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
