It measures 53.20 × 35.30 × 7.10mm and slots directly into the battery compartment. Capacity is 3.89Wh — identical to the original specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCompact camera platform fit:\u003c\/strong\u003e\n    These Medion and Traveler models share the same battery bay dimensions, connector polarity, and voltage rail. The BMS in each body reads cell voltage the same way, so one cell type covers the full group without any adapter or modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the MD41856 body and monitored BMS handshake on first install. The camera accepted the cell after one full charge via the OEM charger, and the battery-remaining indicator tracked correctly across the full discharge curve.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge protocol on compact BMS cameras:\u003c\/strong\u003e\n    Run the first full charge from inside the camera body or with the OEM charger — not a third-party USB adapter. Some Medion compact bodies need that first camera-body charge cycle to calibrate the fuel gauge and display accurate shot-remaining counts.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFlash output dropping mid-shoot on a new replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe capacitor that powers the flash draws a sharp recharge current spike after every shot. A new cell that hasn't completed its first full charge cycle may sit at a slightly lower resting voltage, which causes the camera to throttle flash recharge current as a protective measure. The result is longer recycle times and visibly underexposed flash frames partway through a session. Charge the cell fully before your first shoot and the issue clears — the camera needs to see the cell at or above 4.1V on first use to allow full capacitor draw.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically on the LCD\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Medion compact body maps percentage to fixed voltage thresholds written for the original cell's discharge curve. A replacement cell with a slightly different discharge profile can cause the indicator to skip from 80% to 40% without warning, or hold at one level for a long time then drop suddenly. This is a display mapping issue, not a capacity fault. After two or three full charge-discharge cycles through the camera body, the BMS recalibrates its threshold readings and the percentage display stabilises.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333914263642,"sku":"BWCS-NP60FU-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333914296410,"sku":"BWCS-NP60FU-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333914329178,"sku":"BWCS-NP60FU-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NP60FU-1.webp?v=1778213591","url":"https:\/\/batteryweb.com\/products\/medion-md41856-replacement-battery-37v-1050mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
