Dell Digital Jukebox S-D0910A Replacement Battery 3.7V 1050mAh

Dell Digital Jukebox — 3.7V Li-Polymer Replacement Battery (S-D0910A)

This 3.7V, 1050mAh Li-Polymer battery replaces the S-D0910A cell in the Dell Digital Jukebox series, including the Jukebox DJ, Jukebox DJ 1st, and Jukebox 2nd generation models. It fits players that have lost the ability to hold a charge or will no longer power on from the original cell. Swap it in when the factory cell has degraded past usable capacity.

• Digital Jukebox series fit: These models share the same 3.7V single-cell architecture, connector pinout, and BMS communication protocol — the S-D0910A part number covers the full range without modification.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on Dell Jukebox hardware and confirmed the BMS handshake completed correctly, charge termination triggered at the expected cutoff voltage, and the player's battery indicator updated accurately across the full state-of-charge range.
• First charge after cell swap: After fitting this battery, connect the player to its charger and allow a full uninterrupted charge before use. Players that have sat without a cell — or with a fully dead cell — can enter a deep-discharge protection state where the device shows no response until trickle current has been applied for at least 30 minutes.

Battery percentage jumping erratically after cell swap

The Dell Jukebox estimates charge level by mapping voltage to a percentage table calibrated to the original cell's discharge curve. A new cell starts with a slightly different resting voltage than a depleted original, so the indicator recalculates at startup and can show unexpected jumps. This settles after one or two full charge and discharge cycles as the firmware re-anchors its voltage thresholds to the new cell. Run the player down to auto-shutoff, charge fully to 4.2V, and repeat once — the readout stabilises.

Playback cutting out before the battery indicator shows empty

The audio amplifier circuit in the Jukebox draws a brief current spike when driving headphone output at higher volumes. Near the end of the cell's discharge curve, voltage sags under that load below the amplifier's minimum operating threshold — the player cuts audio or shuts down even though the indicator still shows remaining charge. This is a voltage-sag issue, not a capacity issue. If it happens consistently, let the player shut down fully, then charge to 100% before the next use to keep the cell in the upper part of its voltage range.
