DXG-5C0 Digital Camera Replacement Battery 3.7V 720mAh

DXG DXG-5C0 Series — 3.7V Li-ion Replacement Battery

This is a 3.7V 720mAh Li-ion replacement cell for DXG compact point-and-shoot cameras. It fits the DXG-5C0, DXG-5C0V, DXG-5C8V, DXG-5C8VR, and one additional model in the same series. Dimensions are 39.50 × 35.40 × 5.60mm — match these before ordering if you are unsure which variant you have.

• DXG-5C0 series fit: These models share the same battery bay dimensions, contact pin layout, and 3.7V charging rail. One cell covers the full group without modification.
• Bench tested on actual hardware: We cycled this cell through the camera body charger and monitored BMS handshake on first connection. The cell was accepted without a rejection event, and charge termination triggered correctly at full capacity.
• First-cycle charge protocol: Run the first full charge through the OEM charger or directly in the camera body before shooting. Some DXG BMS firmware maps the battery-remaining indicator to a discharge curve — it needs one supervised cycle to report remaining charge accurately on the display.

Battery percentage jumping erratically on the DXG-5C0 display

The DXG-5C0 uses a voltage-threshold method to estimate remaining charge. A new replacement cell has a slightly different discharge curve than the depleted original, so the camera's lookup table maps voltage to percentage incorrectly at first. You may see the indicator jump from 80% to 20% mid-session or hover at full for longer than expected. After two or three full discharge-and-charge cycles in the camera body, the display stabilises as the BMS adjusts to the new cell's actual voltage profile.

Flash not fully recycling between shots after extended use

The onboard flash capacitor pulls a short, high-current burst from the cell each time it recharges. As the cell approaches the lower end of its discharge curve — roughly 3.4V — available current drops and the capacitor takes longer to reach full charge voltage. The result is a dimmer flash or a longer wait between shots, even though the battery indicator may still show charge remaining. If you notice this pattern, charge the battery before the next session rather than shooting the cell down to cutoff.
