It replaces OEM part numbers BTP-BGBM, BTP-BFBM, and 40018875. The connector and BMS handshake match the original Medion battery specification for these models.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMD96442 \/ MD96559 \/ MD96570 \/ MD97900 compatibility:\u003c\/strong\u003e\n    These notebooks share the same 10.8V battery platform, connector pinout, and BMS communication protocol — one cell fits all listed models without modification.\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 MD-series board. The BMS accepted the new cell, communicated state-of-charge data correctly, and charge termination triggered at the expected voltage ceiling.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle calibration on Medion notebooks:\u003c\/strong\u003e\n    After fitting this battery, run a 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 appears after every cell swap on Medion firmware.\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 a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eMedion notebooks store battery health data in EEPROM on the old cell. When a new battery is fitted, the BIOS compares the fresh cell against stale EEPROM values and flags it as degraded — even though the cell is new. This is a firmware-side calibration gap, not a fault with the replacement battery. Run one full discharge-to-hibernate cycle followed by a full uninterrupted charge. After two to three cycles, the BIOS fuel gauge IC recalibrates against the actual cell capacity and the health 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 has not yet mapped the new cell's voltage curve — the percentage displayed does not match the actual remaining cell voltage. Under combined CPU and display load, the cell hits a voltage cliff that the OS did not anticipate, and the system shuts off to protect itself. It is not a fault with this battery. Run two full discharge-to-hibernate cycles with the laptop under normal use, then recharge fully each time — the fuel gauge will track the actual voltage curve accurately by the third cycle, and shutdowns at false percentages will stop.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409822253146,"sku":"BWCS-MD9800HB-1","price":133.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409822285914,"sku":"BWCS-MD9800HB-2","price":153.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409822318682,"sku":"BWCS-MD9800HB-3","price":169.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MD9800HB-1.webp?v=1779581092","url":"https:\/\/batteryweb.com\/products\/medion-md96442-replacement-battery-108v-8800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
