About this replacement
Creative Nomad Jukebox ZenTouch — 3.7V Li-Polymer Replacement Battery (DAA-BA0004)
This 3.7V, 1500mAh Li-Polymer cell replaces the original battery in the Creative Nomad Jukebox ZenTouch, Zen Touch 20GB, Zen Touch 40GB, and DAP-HD0014. It fits the same footprint as the factory pack at 86.17 × 49.05 × 3.90mm. Capacity matches the OEM spec at 5.55Wh.
- ZenTouch 20GB and 40GB compatibility: Both storage variants use the same 3.7V single-cell architecture and share the DAA-BA0004 connector pinout. The BMS handshake is identical across both, so one cell covers the full ZenTouch line.
- Bench tested on actual hardware: We cycled this cell through charge and discharge on the ZenTouch platform. The BMS accepted full charge current without triggering protection cutoff, and voltage held steady through the discharge curve under audio playback load.
- First charge after installation: After a cell swap, connect the ZenTouch to its charger before powering on. Media players frequently enter deep-discharge protection after a flat or removed cell — supplying charge current first lets the BMS trickle the cell back above the wake threshold before the device attempts to boot.
Battery percentage jumping after cell swap on the ZenTouch
The ZenTouch reads state-of-charge using a voltage-threshold lookup tied to the original cell's discharge curve. After a new cell is installed, the firmware hasn't mapped the new cell's resting voltage to an accurate percentage. The indicator will show erratic jumps — sometimes 20–30% at once — during the first few charge and discharge cycles. Run two or three full cycles and the display will stabilise as the firmware recalibrates its threshold table against the new cell's actual voltage behaviour.
Playback cutting out before the battery indicator shows empty
The audio amplifier in the ZenTouch draws a short current spike each time it drives output, and at the tail end of a discharge cycle the cell voltage sags enough to fall below the amplifier's minimum rail. The device cuts audio — or shuts down — while the battery indicator still shows a residual charge percentage. This happens because the indicator is reading resting voltage, not load voltage. If playback stops unexpectedly, reconnect the charger and let the cell recover to at least 3.7V before resuming.
