It fits MD97107, MD97295, MD97164, and over a dozen other Akoya Mini variants sharing the same connector and BMS handshake. Capacity figures come from the product data — not extrapolated from web sources.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAkoya Mini E1311 and MD-series fit:\u003c\/strong\u003e\n    These models share a common 11.1V three-cell architecture, the same physical connector, and a compatible BMS communication protocol. A single cell design spans the full MD97xxx range because Medion kept the battery bay and power rail consistent across that generation of Akoya Mini hardware.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge, full load discharge, and BMS handshake verification on Akoya Mini hardware. The BMS cleared correctly, charge acceptance reached rated capacity, and no protection-circuit trips occurred during the test cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle calibration on the E1311:\u003c\/strong\u003e\n    After installing, run one full discharge until the laptop hibernates on low battery, then charge uninterrupted to 100% without interruption. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap on Akoya Mini models.\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 immediately after replacement\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Akoya Mini E1311 BIOS reads EEPROM data embedded in the original battery cell. When a new cell is installed, that EEPROM data resets, and the BIOS interprets the mismatch as degraded or unknown health. This is not a fault with the replacement cell. Running one full discharge-to-hibernate followed by an uninterrupted charge to 100% forces the BIOS to rewrite its learned battery profile. After two or three full cycles, the health indicator normalises and reports accurately.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shutting down at 20–30% charge shown on the gauge\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 discharge curve. The old cell's curve is still cached, so the gauge misreads remaining capacity and the laptop cuts out well before the displayed percentage reaches zero. The fix is three full discharge-to-hibernate and full charge cycles — no partial charges in between. After the third cycle the fuel gauge IC recalibrates and the shutdown-at-30% behaviour stops.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409813274714,"sku":"BWCS-MSX400NB-1","price":69.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409813307482,"sku":"BWCS-MSX400NB-2","price":81.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409813340250,"sku":"BWCS-MSX400NB-3","price":89.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MSX400NB-1.webp?v=1779581059","url":"https:\/\/batteryweb.com\/products\/medion-akoya-mini-e1311-replacement-battery-111v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
