Medion MD86063 Compatible Battery 3.7V 720mAh

Medion MD86063 / MD85416 Series — 3.7V Li-ion Replacement Battery (VG0376122100001)

This 3.7V, 720mAh lithium-ion cell replaces the original Medion VG0376122100001 battery used across the MD86063, MD85416, MD85562, MD86084, and related compact digital camera models. It matches the original voltage, physical footprint (39.50 × 35.40 × 5.60mm), and connector orientation so the cell seats correctly in the battery bay. Capacity figures are sourced directly from product data — 720mAh / 2.66Wh.

• MD86063 / MD85416 series compatibility: These models share the same battery bay dimensions, 3.7V voltage rail, and BMS communication protocol — which is why one cell covers the full range. Swapping a cell rated at a different voltage would trip the protection circuit immediately.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on camera-class test equipment. The BMS accepted the cell without fault codes, and the protection circuit responded correctly to both low-voltage cutoff and thermal threshold events.
• First-cycle BMS initialisation: Charge this cell fully inside the camera body or OEM charger before your first shoot. Some Medion compact camera BMS systems need one complete in-body charge cycle before they begin tracking battery-remaining percentage accurately — skipping this step can cause the indicator to read incorrectly from the start.

Why the MD86063 displays a dead-battery icon on a replacement cell that still has charge

Medion compact cameras map their battery indicator against a voltage-discharge curve programmed for the original cell. A new replacement cell can have a slightly different discharge curve shape, particularly in the mid-range between 3.9V and 3.7V. The camera's indicator logic reads the voltage at that point and maps it to an empty or near-empty state even when usable capacity remains. Running one full charge-to-depletion cycle inside the camera body allows the BMS to recalibrate its threshold mapping against the actual curve of the new cell.

Flash not fully recycling between shots

When the flash capacitor recharges between shots, it draws a short but sharp current spike from the battery. Toward the end of a discharge cycle — typically below 3.6V — the cell's internal resistance rises and it can no longer supply that spike cleanly. The result is a slower recycle time or a visibly weaker flash output. This is normal cell behaviour, not a fault with the replacement unit. If recycling slows significantly, check the camera's battery indicator — once voltage recovers above 3.7V on a fresh charge, flash output returns to full strength.
