Sencor SPV2706 Portable DVD Replacement Battery 7.4V 1900mAh

Sencor SPV2706 / SPV2715 / SPV2716 / SPV2718 — 7.4V Li-Polymer Replacement Battery (GSP613762)

This 7.4V, 1900mAh Li-Polymer battery replaces part number GSP613762 in the Sencor SPV2706, SPV2715, SPV2716, and SPV2718 portable DVD players. It slots into the same bay as the original and connects to the same BMS circuit. Capacity is 1900mAh (14.06Wh), matching the factory specification.

• SPV2706 / SPV2715 / SPV2716 / SPV2718 compatibility: These four models share the same 7.4V two-cell Li-Polymer pack, the same connector pinout, and the same BMS handshake protocol — so one battery covers the full range without modification.
• Bench tested on actual hardware: We cycled this pack through disc spin-up, sustained playback, and display-on load simultaneously. The BMS held voltage within the expected window and did not trigger low-voltage cutoff during the draw spike at disc motor start.
• Charging while playing: Avoid running disc playback with the display at full brightness while the unit is on charge. The combined draw from the disc motor, backlight, and charging current stacks heat into the cell. The thermal protection circuit will throttle output before damage occurs, but repeated thermal events shorten cell life faster than normal cycling.

Why the SPV2706 won't complete a full movie on a new battery

The SPV2706 draws from three sources at once — disc motor, display backlight, and audio amplifier. At disc spin-up, the motor pulls a short current spike that can temporarily sag cell voltage below what a deeply discharged or storage-state battery can sustain. If the pack ships at storage voltage (typically around 3.7V per cell), the player may cut off before the disc even reaches play speed. A full charge before first use resolves this. Once fully charged, the 1900mAh capacity supports extended playback without voltage sag during normal motor operation.

Screen dimming mid-movie with no warning

When cell voltage drops below a threshold — typically around 3.2V per cell under load — the SPV display driver reduces backlight brightness to lower current draw and protect the cell. This is not a screen fault; it is the player's low-voltage response. If dimming starts earlier in playback than expected, the original battery's capacity has degraded and it can no longer sustain the full display load through a complete film. Fit the replacement GSP613762 pack, charge to 100%, and the display will hold full brightness through a normal viewing session.
