Vivitar Vivicam 3795 Compatible Battery 3.7V 1050mAh

Vivitar Vivicam 3795 / 3930 / 4000 Series — 3.7V Li-ion Replacement Battery (02491-0006-10)

This is a 3.7V 1050mAh Li-ion replacement cell for the Vivitar Vivicam 3795, Vivicam 3930, Vivicam 4000, DVR-390H, and over a dozen additional Vivitar compact digital camera models. It matches the OEM footprint at 53.20 × 35.30 × 7.10mm and drops into the same battery bay without modification. Voltage and capacity are drawn from product data — 3.7V nominal, 3.89Wh total.

• Multi-model Vivitar platform fit: These Vivicam and DVR models share a common battery bay spec and connector pinout across the range. The BMS in each body reads the same voltage thresholds, so one cell covers the full lineup without electrical conflict.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles monitoring BMS handshake, cutoff voltage, and cell acceptance. The BMS accepted the cell without tripping a reject flag, and cutoff triggered cleanly at the low-voltage threshold.
• First charge cycle on the Vivicam: On first install, run one full charge via the camera body or OEM charger before shooting. Some Vivitar BMS firmware maps the battery-remaining indicator to a discharge curve that only calibrates after one complete charge cycle from inside the camera body — skipping this step can cause the indicator to read inaccurately from the first frame.

Flash not fully recycling between shots on the Vivicam 3795

The Vivicam 3795 flash capacitor draws a sharp current spike to recharge between shots. As cell voltage sags toward the lower end of its discharge curve, that recharge current drops, and the capacitor takes longer to reach full charge. The result is a dimmer flash output on rapid successive shots — not a fault in the flash unit itself, but a cell delivery issue. If this starts happening mid-session, the cell is approaching its lower voltage threshold; charge before the next shoot rather than continuing.

Battery percentage jumping erratically on the Vivicam display

The Vivicam battery indicator maps display segments to fixed voltage thresholds calibrated to the OEM cell's discharge curve. A new third-party cell discharges along a slightly different curve, so the indicator can jump — dropping two bars at once, then holding flat for a long stretch. This is a firmware mapping mismatch, not a fault with the replacement cell. Completing one or two full charge and discharge cycles via the camera body allows the BMS to track the new cell's curve more accurately; after that, the indicator stabilises. If it continues jumping after three cycles, confirm the cell is reaching 4.2V at full charge.
