About this replacement
AgfaPhoto Realishot DC5200 — 3.7V Li-Polymer Replacement Battery (ZK01)
This 3.7V, 450mAh lithium-polymer cell replaces the ZK01 battery in the AgfaPhoto Realishot DC5200 compact digital camera. It restores power to the camera body for photo and video capture. Dimensions are 37.40 × 32.60 × 5.70mm — confirm against your original cell before fitting.
- Realishot DC5200 fit: The DC5200 draws from a single-cell Li-Polymer pack at 3.7V nominal. This cell matches that voltage rail and the ZK01 form factor, so the battery door closes and the contacts seat correctly without modification.
- Bench tested on actual hardware: We cycled this cell through the DC5200 body and monitored BMS handshake at insertion. The camera accepted the cell without error codes, and charge termination triggered correctly at full capacity.
- First-cycle conditioning on the DC5200: Charge this cell fully inside the camera body before your first shoot. Some compact camera BMS implementations only calibrate the battery-remaining indicator after one complete in-body charge cycle — skipping this step can cause the display to read inaccurate percentage values from the start.

The DC5200 maps its battery indicator to a fixed voltage-threshold curve tuned to the original ZK01's discharge profile. A new replacement cell can sit at 3.6V — genuinely charged — but the camera reads it as flat because its internal threshold table expects a different resting voltage at that state of charge. One full in-body charge cycle from 0% to 100% resets the mapping. After that cycle, the indicator tracks the actual charge level correctly.
Battery percentage jumping erratically during a shoot
This happens when the camera's voltage-to-percentage conversion loses its reference point mid-session. Flash capacitor recharge events pull burst current that causes a momentary voltage sag — the camera misreads that sag as a sudden drop and updates the indicator accordingly. The fix is to allow one full discharge and recharge cycle so the BMS can build an accurate internal model of the cell's discharge curve. If jumping persists after two full cycles, check that the battery contacts on both the cell and the door are clean and making firm contact.
