Insignia NS-DV111080F Replacement Battery 3.7V 1800mAh

Insignia NS-DV111080F — 3.7V Li-ion 1800mAh Replacement Battery

This 3.7V, 1800mAh lithium-ion cell is a direct replacement for the Insignia NS-DV111080F digital camcorder. It slots into the same battery bay and connects to the same contacts as the original. Capacity figures are taken from product data — 1800mAh, 6.66Wh.

• NS-DV111080F compatibility: The NS-DV111080F uses a single-cell 3.7V Li-ion pack with a compact footprint — 53.00 × 35.30 × 11.00mm. This cell matches that voltage rail and physical profile so the door closes flush and the BMS negotiation completes normally.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on the NS-DV111080F platform. The BMS accepted the cell without fault codes, and the charge circuit brought it to full termination voltage without interruption.
• First-cycle charge protocol for camcorders: On the NS-DV111080F, charge the replacement cell through the camera body before your first recording session. Some compact camcorder BMS systems only calibrate the battery-remaining indicator after completing one full charge cycle inside the device itself — not in a standalone charger.

Dead battery indicator showing on a cell that's not empty

The NS-DV111080F maps its battery gauge to a discharge voltage curve calibrated against the original cell's chemistry profile. A fresh replacement cell can have a slightly different resting voltage at equivalent charge states, which causes the indicator to read low or show empty prematurely. This is a calibration gap, not a faulty battery. Run one full charge-to-discharge cycle through the camera body and the indicator typically resets to an accurate read.

Battery percentage jumping around during recording

Video recording draws harder than playback — the sensor, processor, and write buffer pull current simultaneously and create voltage sag on the cell. If the BMS sees the terminal voltage dip below a threshold during a recording burst, it can log the cell as lower capacity and the display percentage drops suddenly. This isn't capacity loss — it's the indicator responding to instantaneous voltage sag rather than true state of charge. Charge the cell fully to 4.2V before a recording session so the starting headroom keeps sag away from the low-voltage thresholds.
