It is a direct cell replacement when the original battery no longer holds a charge or has physically swollen. Capacity is 1250mAh (4.63Wh) — matching the original cell specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMDPNA 15000 \/ MD96700 platform fit:\u003c\/strong\u003e\n    These four Medion models share the same battery bay dimensions (53.44 × 37.14 × 7.66mm), connector pinout, and BMS communication protocol — so one cell fits across the group without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on the MD96700 platform. The BMS accepted the cell on first insertion, completed a full charge cycle without thermal event, and voltage held steady at 3.7V nominal under screen and modem load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    Disable any fast-charge mode for the first complete discharge-charge cycle after installation. This gives the fuel gauge IC time to map the new cell's discharge curve before high-current charging begins on an uncalibrated cell.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% on the replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new Li-ion cell has a steeper voltage drop near the low end of its discharge curve compared to a used cell the fuel gauge IC was originally calibrated against. The phone's SoC interprets this voltage cliff as a fault and cuts power to protect the modem and storage. This is not a defective cell — it is a calibration mismatch. Run one full uninterrupted discharge to 0% shutdown, then charge to 100% without interruption; the fuel gauge IC will re-anchor its curve and the cutoff will move back to the correct low-voltage threshold near 3.4V per cell.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone reports wrong battery percentage after cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe fuel gauge IC stores a learned discharge profile from the old cell in its coulomb counter registers. After a cell swap, those stored values no longer match the new cell's actual capacity, so the percentage readout drifts — often reading 100% within minutes of charging or dropping suddenly from 60% to 15%. One full discharge-charge cycle rewrites the coulomb counter baseline against the new cell. After that cycle, percentage reporting stabilises to within the normal ±3–5% tolerance of the IC.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405146783834,"sku":"BWCS-MIOA201SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43405146816602,"sku":"BWCS-MIOA201SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43405146849370,"sku":"BWCS-MIOA201SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MIOA201SL-1.webp?v=1779370263","url":"https:\/\/batteryweb.com\/products\/medion-mdpna-15000-replacement-battery-37v-1250mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
