Sencor SPV2918 Replacement Battery 7.4V 1900mAh Li-Polymer

Sencor SPV2918 / SPV2919 / SPV 7912T — 7.4V Li-Polymer Replacement Battery (GSP613762-2S1P)

This is a 7.4V, 1900mAh Li-Polymer battery that replaces part number GSP613762-2S1P in the Sencor SPV2918, SPV2919, and SPV 7912T portable DVD players. It restores cordless operation when the original cell can no longer hold enough charge to complete a full movie. Dimensions are 72.80 × 63.60 × 6.90mm — confirm these against your original before ordering.

• SPV2918 / SPV2919 / SPV 7912T fit: All three models share the same GSP613762-2S1P cell format, voltage rail, and connector pinout. The BMS on each player communicates the same charge termination signal, so one replacement covers all three without modification.
• Bench tested on actual hardware: We cycled this battery through full charge and discharge on the SPV2918 platform. The BMS accepted charge correctly, hit the 4.2V-per-cell cutoff cleanly, and held stable voltage through disc spin-up events without triggering overcurrent protection.
• Simultaneous load warning: Avoid running this player plugged in while the disc is spinning and the backlight is at full brightness. That combination stacks charging current on top of motor and display draw, raises cell temperature, and can cause the thermal protection circuit to throttle output before the battery is fully charged.

Disc not spinning after fitting a new battery

The disc motor on the SPV2918 pulls a short but sharp current spike at spin-up. If the replacement cell shipped at low storage voltage — typically around 3.7V per cell — the BMS may cut output the moment that spike hits, before the disc reaches reading speed. This looks like a dead player but is a voltage issue, not a fault. Charge the battery fully to 8.4V before the first use and the spin-up surge will clear without tripping the overcurrent threshold.

Screen dimming mid-movie even with a charged battery

The display driver in this player monitors the voltage rail and steps down backlight power when it detects sag. If the cell has aged or was stored discharged for an extended period, internal resistance rises and voltage sags under the combined disc and display load — even if the battery indicator still shows charge. The fix is a full slow charge: plug in, leave for at least three hours without using the player, then check whether brightness holds steady at the 60-minute mark. If it still dims, the cell's capacity has degraded below a usable threshold and replacement is the next step.
