Kodak DCS-520 Replacement Battery 7.2V 2150mAh Ni-MH

Kodak DCS-520 / DCS-560 / DCS-620 Series — 7.2V Ni-MH Replacement Battery (4E0111)

This 7.2V 2150mAh Ni-MH battery replaces the original cell in Kodak DCS-520, DCS-560, DCS-620, and DCS-620x professional digital SLR cameras. It matches the OEM voltage rail and physical form factor used across this late-1990s Kodak DCS platform. Capacity is rated at 15.48Wh.

• DCS-500 and DCS-600 platform compatibility: The DCS-520, DCS-560, DCS-620, and DCS-620x share the same battery bay geometry, contact layout, and 7.2V nominal voltage rail. One cell covers the full range without modification.
• Bench tested on actual hardware: We cycled this cell through the DCS camera body and monitored BMS handshake and charge acceptance. The cell reached full charge without triggering a rejection flag, and discharge tracking stayed consistent across multiple cycles.
• First-cycle initialisation on the DCS body: Run the first full charge from inside the camera body or OEM charger before shooting. The DCS BMS calibrates its remaining-charge display against the new cell's discharge curve during that initial cycle — skipping it can cause erratic battery-level readings in the viewfinder.

Why the DCS-520 battery indicator drops suddenly at moderate charge levels

The Kodak DCS-520 uses a voltage-threshold method to estimate remaining charge — it maps specific voltage points to percentage brackets. Ni-MH cells have a flatter discharge curve than the BMS expects from a degraded original cell, so the indicator can jump from a mid-level reading to near-empty without warning. This is a calibration mismatch, not a cell fault. Running two full charge-discharge cycles through the camera body teaches the BMS to map thresholds more accurately against the new cell's actual curve.

Camera body warm and battery draining faster than expected during tethered capture sessions

The DCS-520 and DCS-620 route image processing, CCD readout, and PC card writing simultaneously during tethered shooting — total draw climbs well above the baseline spec. The Ni-MH cell handles sustained current draws differently from the degraded OEM cells most users compare against, but back-to-back tethered captures with the LCD active will deplete any 2150mAh cell faster than single-shot field work. Keep the LCD off between frames when shooting tethered. If the body is warm to the touch, let it rest for several minutes before continuing — the CCD and processor both contribute heat that the BMS reads as elevated cell temperature, which can trigger an early low-voltage cutoff at around 6.0V.
