JTC VideoShot DVH20 Replacement Battery 3.7V 1050mAh

JTC VideoShot DVH20 Series — 3.7V Li-ion Replacement Battery

This 3.7V, 1050mAh Li-ion cell replaces the original battery in the JTC VideoShot DVH20, DVH22, DVH1080, and DVH5330 compact digital cameras. It restores power to the recording, playback, and still-image functions that the degraded factory cell can no longer sustain. Voltage and physical dimensions match OEM spec: 53.20 × 35.30 × 7.10mm.

• VideoShot DVH series compatibility: The DVH20, DVH22, DVH1080, and DVH5330 share the same battery bay dimensions and 3.7V supply rail, so one cell fits the full range without modification.
• Bench tested on actual hardware: We cycled this cell through the DVH20 body and confirmed the BMS accepted the new cell at both the charge and discharge stage, with no fault flags triggered during continuous video capture.
• First-cycle conditioning for accurate indicator readout: Run one complete charge cycle through the OEM charger or the camera body itself before heavy shooting — the DVH series BMS maps its battery-remaining display against a charge curve it reads during that first full cycle, and skipping it produces erratic percentage readings.

The DVH series battery indicator is calibrated to the discharge curve of the original cell. A new Li-ion cell has a slightly different internal resistance profile, so the camera misreads state-of-charge on the first few cycles. The indicator may show empty at 3.65V — well above the actual cutoff threshold. After two to three full charge-discharge cycles, the BMS recalibrates and the readout stabilises.

During sustained video recording, the DVH20's combined sensor readout, video processor, and LCD draw pull current in bursts rather than at a steady rate. A replacement cell with a fresh discharge curve responds to those current spikes with small voltage dips, which the camera's voltage-threshold indicator interprets as sudden capacity drops. This is a display mapping issue, not a fault with the cell. It typically settles after the BMS has seen one full discharge to the 3.0V cutoff floor.
