Medion MD86276 Compatible Battery 3.7V 660mAh Li-ion

Medion MD86276 / MD86350 — 3.7V Li-ion Replacement Battery (VG037612210001)

This 3.7V 660mAh Li-ion cell fits the Medion MD86276 and MD86350 compact digital cameras, along with over 40 additional Medion models sharing the same battery bay. It replaces the original cell when the camera no longer holds a charge or powers on. Capacity is 660mAh (2.44Wh), matching the OEM specification.

• MD86276 / MD86350 platform fit: These Medion compact cameras share the same 3.7V single-cell architecture, battery footprint (40.00 × 31.10 × 5.90mm), and connector orientation. A cell that seats correctly in one will seat correctly in the others across this range.
• Bench tested on actual hardware: We cycled this cell through the Medion camera body and an external Li-ion charger. The BMS accepted the cell without a fault flag, and charge termination triggered cleanly at 4.2V on both paths.
• First charge cycle on the Medion body: Before heavy shooting, run one full charge cycle from inside the camera body itself. Some Medion BMS implementations only calibrate the battery-remaining display after seeing a full in-body charge cycle — skipping this step can cause the indicator to read inaccurately from the start.

Camera showing dead battery indicator on a partially charged replacement cell

Medion compact cameras map remaining charge to voltage thresholds tuned to the discharge curve of the original cell. A new third-party cell can sit at a slightly different resting voltage for the same state of charge. The camera reads that offset as a low or dead battery even when the cell is not depleted. Running one full in-body charge cycle recalibrates the threshold mapping so the indicator tracks accurately.

Flash not fully recycling between shots on a new cell

The flash capacitor draws a sharp recharge current after each burst. At 660mAh, this cell is working near capacity when the camera runs flash, LCD, and autofocus simultaneously. If recycle time lengthens noticeably between shots, the cell voltage is sagging under combined load — not a fault in the cell itself. Let the camera sit for two to three seconds between flash shots to allow voltage recovery, and confirm the cell is charged to at least 4.1V before a heavy shooting session.
