Vivitar DVR-560G Replacement Battery 3.7V 850mAh Li-ion

Vivitar DVR-560G / Vivicam Series — 3.7V Li-ion Replacement Battery

This 3.7V 850mAh (3.15Wh) Li-ion cell replaces the original battery in the Vivitar DVR-560G, Vivicam 3660, Vivicam 7388, and Vivicam 7388S compact camcorders. It matches the original cell's dimensions at 40.20 × 35.30 × 6.10mm, so it seats flush in the battery compartment without modification. Voltage and capacity are spec-matched to the original to keep the camera's charge indicator functioning correctly.

• DVR-560G and Vivicam platform fit: These models share a common battery bay size and the same 3.7V single-cell architecture. No BMS handshake or proprietary authentication token is required — the camera reads cell voltage directly to report charge status.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on a 3.7V Li-ion test rig. The BMS cutoff triggered cleanly at the low-voltage threshold with no premature shutdown, and the cell reached full rated capacity within two standard charge cycles.
• First-install charge cycle: Charge this cell fully inside the camera body or OEM charger before your first recording session. Some Vivicam bodies need one complete in-body charge cycle to calibrate the battery-remaining display to the new cell's discharge curve — skipping this can cause the indicator to read erratically.

Battery percentage jumping on the DVR-560G display after fitting a new cell

The DVR-560G maps battery percentage to fixed voltage thresholds tuned to the original cell's discharge curve. A new cell discharges along a slightly different curve during its first few cycles, so the indicator can jump — for example, dropping from 80% to 40% mid-session without warning. This is a display calibration issue, not a fault with the cell. Run two full charge-discharge cycles inside the camera body and the indicator will settle. After calibration, expect the display to track accurately through the full range from 4.2V charged down to the 3.0V cutoff.

Camera shows dead-battery icon immediately after fitting a charged replacement

This happens when the cell voltage sits just below the camera's wake threshold — typically around 3.5V — often because the replacement cell self-discharged during storage. The camera reads the low resting voltage and refuses to boot. Place the cell in the OEM charger or a standalone Li-ion charger and run a full charge cycle before inserting it again. Once the cell reaches 4.2V, the camera will power on normally and the dead-battery icon will clear.
