Direct replacement battery

The Cameron & Co DS-CS-HD1SL is a lithium-polymer battery built to fit the Sony NW-HD1 20 GB digital media player. It matches the original PMPSYHD1 part and restores portable playback for owners of that device.

Sustained playback performance

Rated at 3.7 V and 800 mAh, the cell delivers a steady 0.8 Ah capacity for extended listening sessions. Lithium-polymer chemistry maintains stable voltage under continuous discharge rather than fading after a short burst.

51.21 x 33.30 x 3.60 mm form factor

The pack measures 51.21 by 33.30 by 3.60 millimetres, so it seats correctly in the NW-HD1 battery compartment. Builders working on other players or needing a different footprint will need another model.
