Replacement battery for Harman/Kardon SOHO

This lithium-polymer pack is built for the Harman/Kardon SOHO P462539 wireless headset. It delivers 3.7 V and 480 mAh capacity in a slim black cell. The unit matches the original P462539 part number and measures 40.50 x 25.46 x 5.12 mm. Buyers with other headset models will need a different battery.

Direct-fit cell restores original runtime

The pack installs inside the earcup without adapters or soldering. Its 1.78 Wh rating matches the factory specification so charging circuits and fuel-gauge readings stay accurate. No software, cables or tools are included in the package. Users who want a higher-capacity upgrade cannot achieve it with this part.

480 mAh suits daily commutes and office calls

At the rated capacity the headset covers typical listening sessions between charges. Heavy users who run the headset continuously at high volume will reach the limit sooner. The cell chemistry does not support fast-charge protocols beyond the headset's built-in controller. Anyone needing multi-day autonomy should consider a wired alternative.

Questions about this item

How often will the 3.7 V 480 mAh Li-Polymer cell need replacing under daily use?

Expect two to three years before capacity drops below useful levels; the pack is a direct 100 % OEM-compatible swap for part number P462539.

What stops the headset first during a marathon session — the 1.78 Wh capacity or heat?

The 1.78 Wh rating is the hard limit; once the 480 mAh charge is spent the headset powers down, and the slim 5.12 mm profile leaves little thermal mass.

Does the 40.50 × 25.46 mm pack get hot or whine after hours of streaming?

No moving parts and low internal resistance keep it silent; only mild warmth appears near the end of a full 480 mAh discharge cycle.
