Magnavox CVL-345 Replacement Battery 6V 2100mAh Ni-MH

Magnavox CVL-345 / CVL-610 Series — 6V Ni-MH Replacement Battery

This is a 6V, 2100mAh Ni-MH replacement battery for the Magnavox CVL-345, CVL-610, CVL-612, CVL-620, and six additional CVL-series camcorders. It slots into the same battery bay as the original and restores power for recording and playback. Voltage and form factor match OEM spec across the listed models.

• CVL-series camcorder compatibility: These models share a common 6V battery rail and identical mechanical bay dimensions. The same connector pinout and voltage threshold applies across the lineup, which is why one cell covers all listed variants without modification.
• Bench tested on actual hardware: We cycled this cell through full charge and discharge on a CVL-series body. The BMS accepted the cell without rejection flags, and voltage under load held steady through both recording and playback draw cycles.
• First-cycle initialisation on CVL camcorders: Run the first full charge through the camcorder body itself using the OEM AC adapter — not a standalone charger. Some CVL-series units map battery-remaining display to a charge curve calibrated during the first in-body charge cycle. Skipping this step can cause the indicator to read inaccurately from the start.

Why the CVL-345 shows a dead battery indicator on a partially charged replacement cell

The CVL-series battery indicator maps to specific voltage thresholds baked into the camera firmware. A new Ni-MH cell has a slightly different discharge curve than a worn OEM cell, so the camcorder can misread remaining charge at the top end. This shows up as a sudden drop to one bar or a blinking icon even when the cell still has capacity. Running one full charge-discharge cycle in the camera body lets the firmware re-anchor its threshold mapping to the new cell's actual curve.

Battery percentage jumping erratically during recording

Ni-MH cells have a flatter mid-range discharge curve than Ni-Cd, and the CVL-series indicator was not always tuned for this. As draw spikes during active recording — autofocus, tape transport motor, and viewfinder backlight all pulling simultaneously — voltage dips briefly, triggering a lower indicator reading before recovering. This is a display artefact, not cell failure. If the jumps stop after the first full cycle, the BMS has recalibrated. If they persist past three full cycles, check that resting voltage off the charger reaches 6.0V before inserting.
