STARNOVO 3.7V 800mAh Li-ion Polymer Battery for Sony NW-HD1 NW-HD2

SKU CH-HNB0-86AV9

Replacement lithium-ion polymer battery delivering 800 mAh at 3.7 V for Sony NW-HD1 and NW-HD2 players

  • Compatible with Sony NW-HD1 and NW-HD2 players
  • 800 mAh capacity gives extended playback time
  • 7 V lithium polymer cell weighs only 15 g
  • Certified to UL, CE, UN38.3 and RoHS safety standards
  • Over 300 charge cycles for long service life

Direct replacement battery

This 3.7V lithium-ion polymer cell is built as a drop-in replacement for the Sony NW-HD1 and NW-HD2 portable players. It matches the original form factor so no modification of the battery compartment is required. The pack restores full mobility to devices whose original cells no longer hold a charge. Owners of other players will need a different pack.

800 mAh capacity with certified safety

The 800 mAh rating delivers extended playback time between charges and is rated for over 300 full charge cycles. The cell carries UL, CE, UN38.3 and RoHS certifications and operates safely up to 60 °C (140 °F). Heavy users who need multi-day runtime without recharging will find the capacity limiting.

Compact pack fits original chassis

Measuring 5.0 by 30.5 by 50.0 mm and weighing 15 g, the battery slides into the existing cavity without adhesive or tools. No external charger or special cable is needed; the player’s own charging circuit manages the cell. Builders adding extra capacity or a larger cell must modify the case.

Questions about this item

Will this 3.7V 800mAh Li-ion Polymer battery fit and power my original Sony NW-HD1 or NW-HD2 MP3 player without modification?

Yes, it is a direct replacement for the original battery in the Sony NW-HD1 and NW-HD2 players. The pack dimensions are 5.0 x 30.5 x 50.0 mm and the connector matches the original specification for a proper fit.

How can I verify the battery is performing correctly after installing it in my player?

The player should power on normally and show the expected battery level indicator. With an 800mAh capacity and 3.7V nominal voltage, it should provide long working time and support over 300 charge cycles before significant degradation.

Does the package include only the battery cell or are tools and adhesive strips supplied for the installation?

The box contains the 15g Li-ion Polymer battery cell certified by UL, CE, UN38.3 and RoHS. Installation tools and adhesive strips are not included and must be sourced separately if required for your specific player model.
