It replaces a failed or capacity-depleted original pack. Cross-references include BTY-S25, BTY-S27, MS1006, MS1012, and NB-BT002 among others — check your existing battery label before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMD95020 and compatible models:\u003c\/strong\u003e\n    These Medion notebooks share the same 14.4V battery rail, physical connector, and BMS handshake protocol across the MD95020, MD96100, MD95309, and MD95155 platforms — which is why one cell covers all of them.\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 compatible Medion hardware. The BMS communicated correctly with the system, accepted a full charge without interruption, and held voltage consistently across the discharge curve.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle reset procedure:\u003c\/strong\u003e\n    After installing, 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 commonly appears after a cell swap on these Medion notebooks.\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 after installing a new cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Medion BIOS reads health data from EEPROM embedded in the battery pack — not from live voltage measurements. When you swap the cell, the BIOS compares the new pack's EEPROM signature against the learned profile from the old, degraded battery. The mismatch triggers a false \"replace battery\" or \"poor health\" flag even on a brand-new pack. Running a full discharge-to-hibernate then an uninterrupted charge to 100% forces the BIOS to rewrite its learned profile against the new cell's actual capacity curve.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down at 20–30% shown on the fuel 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 chemistry. The IC inherited calibration data from the old, worn pack — so its voltage-to-percentage mapping is off. Under full CPU and display load, actual cell voltage drops below the shutdown threshold while the gauge still reads 20–30%. Two to three full discharge-and-charge cycles recalibrate the IC against the new cell. After calibration, the gauge should track accurately down to the real cutoff near 11.1V under load.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409815306330,"sku":"BWCS-MSX320NB-1","price":101.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409815339098,"sku":"BWCS-MSX320NB-2","price":116.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409815371866,"sku":"BWCS-MSX320NB-3","price":127.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/batteryweb.com\/products\/medion-md95020-replacement-battery-144v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
