It slots into the same bay as the original BTP-BGBM and restores full unplugged operation. Use the OEM part number BTP-BGBM, BTP-BFBM, or Medion part 40018875 to confirm fitment before ordering.\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 four Medion notebook lines share the same 10.8V battery rail, connector pinout, and BMS handshake protocol — which is why one cell covers all of them. The EEPROM embedded in this pack carries the capacity and chemistry data the BIOS reads on first boot.\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-discharge on the MD96442 platform. The BMS communicated correctly with the BIOS on first insertion, and the fuel gauge IC initialised without error. Charge acceptance was clean from 0% to 100%.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on Medion notebooks:\u003c\/strong\u003e\n    After fitting, 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 that appears after every cell swap on this platform — skipping it leaves the fuel gauge reporting stale data from the old cell.\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 the BTP-BGBM\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eMedion's BIOS reads health status from EEPROM data written during the previous cell's service life. When a new cell goes in, that stored cycle count and degradation history does not auto-clear — the BIOS carries it forward and flags poor health before the new battery has run a single cycle. The fix is a full learn cycle: discharge completely to hibernate cutoff, then charge uninterrupted to 100%. After one or two full cycles the BIOS recalibrates against the new cell's actual chemistry data and the health warning clears.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down abruptly at 20–30% charge shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage cliff problem, not a capacity problem. Under combined CPU and display load, the cell voltage drops faster than the fuel gauge IC tracks — the system hits the low-voltage cutoff threshold while the OS still shows 20–30% remaining. It happens most often on a new or freshly reset cell because the fuel gauge IC has not mapped the new cell's discharge curve yet. Run two or three full discharge-to-hibernate cycles to let the IC calibrate its voltage-to-percentage mapping. After calibration, shutdown should not occur above 5–8% remaining.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409824055386,"sku":"BWCS-MD9800NB-1","price":134.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43409824088154,"sku":"BWCS-MD9800NB-2","price":154.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43409824120922,"sku":"BWCS-MD9800NB-3","price":170.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MD9800NB-1.webp?v=1779581113","url":"https:\/\/batteryweb.com\/products\/medion-md96442-replacement-battery-108v-6600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
