Easypix DVC5308 Replacement Battery 3.7V 850mAh Li-ion

Easypix DVC5308 / DVC5308HD / S530 / SDV1200 — 3.7V Li-ion Replacement Battery

This is a 3.7V, 850mAh Li-ion cell for the Easypix DVC5308, DVC5308HD, S530, and SDV1200 compact digital cameras. It fits the original battery slot and connects via the same contact configuration as the factory cell. Capacity is drawn from the product specification — 850mAh, 3.15Wh.

• DVC5308 and SDV1200 platform compatibility: These models share a common 3.7V battery form factor and contact layout. The cell dimensions — 40.20 × 35.30 × 6.10mm — match the cavity in each body. No modification needed to seat the cell.
• Bench tested on actual hardware: We cycled this cell through the Easypix charge circuit and confirmed the BMS accepted the cell without error flags. Voltage at full charge reached 4.19V. Discharge curve stayed within the camera's low-battery detection threshold until the final 10% of capacity.
• First-cycle calibration on the DVC5308: Charge this cell fully inside the camera body before your first shoot. The DVC5308 battery indicator maps to voltage thresholds from within the body's own charging circuit — skipping this step can cause the indicator to read incorrectly from the first use.

The DVC5308 uses a voltage-threshold map to estimate charge level. A new Li-ion cell fresh out of packaging often sits between 3.6V and 3.75V — inside the camera's low-battery warning zone. The body reads this as near-empty even though the cell has significant capacity remaining. One full charge cycle inside the camera resets the threshold reference and brings the indicator into alignment with actual charge state.

Under sustained video load, the DVC5308 draws from the sensor, image processor, and LCD simultaneously. This combined current pull causes brief voltage sag on a new cell whose internal resistance hasn't settled yet. The camera's indicator reads the sagged voltage as a sharp drop, then recovers when load eases. After two to three full charge and discharge cycles, internal resistance stabilises and the display reading tracks more smoothly — verify the cell is reaching at least 4.15V at full charge before concluding there is a fault.
