It also fits the WIM2070, MD95453, and MD95454. Capacity figures come from the product data — 48.84Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMD95800 and WIM2070 platform fit:\u003c\/strong\u003e\n    These models share the same battery bay geometry, connector pinout, and BMS handshake protocol. The same 11.1V three-cell configuration runs across this entire Medion chassis family, so 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 the MD95800 platform. The BMS completed the handshake correctly, the charge controller accepted full current, and cell voltage held flat across the discharge curve until the low-voltage cutoff tripped at the expected threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on the MD95800:\u003c\/strong\u003e\n    After fitting this cell, run a full discharge 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 Medion platform.\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 this cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe MD95800 BIOS reads EEPROM data embedded in the original cell and compares it against the new one. When those values don't match, it flags the battery as degraded even though the cell is brand new. This is a data mismatch, not a hardware fault. Run one full discharge-to-hibernate then charge to 100% uninterrupted — after one or two complete cycles, the BIOS relearns the cell 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 hasn't calibrated against the new cell yet. The gauge inherited capacity data from the old, degraded battery, so it misjudges where the actual voltage cliff sits. Under combined CPU and display load, the cell voltage drops faster than the stale gauge predicts, and the system shuts off to protect itself. Complete two full discharge-to-hibernate cycles, charging to 100% after each — the fuel gauge IC recalibrates and the reported percentage aligns with real cell voltage by cycle three.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410799099994,"sku":"BWCS-MD9580NB-1","price":115.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43410799132762,"sku":"BWCS-MD9580NB-2","price":131.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43410799165530,"sku":"BWCS-MD9580NB-3","price":145.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MD9580NB-1.webp?v=1779581158","url":"https:\/\/batteryweb.com\/products\/medion-md95800-replacement-battery-111v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
