Replacement Battery for Onyx Studio 3

This 3.7V lithium-ion pack replaces the original PR-633496 cell in the Harman Kardon Onyx Studio 3 wireless Bluetooth speaker. It restores portable operation when the factory battery no longer holds a charge. The unit ships with free installation tools for straightforward user replacement. It is not compatible with Onyx Studio 1, 2 or 4 models.

2600mAh Capacity and 9.62Wh Energy

The 2600mAh rating delivers the same nominal capacity as the original battery, providing comparable playback time on a full charge. At 9.62Wh the pack stays within standard lithium-ion energy limits for safe transport and handling. Runtime scales with volume level and audio content, so very high output will deplete the charge faster. The battery is designed for cyclic daily use rather than continuous high-drain operation.

Direct PR-633496 Swap Without Soldering

This unit is a drop-in substitute for the PR-633496 part number, matching the connector and form factor so no soldering or adapter cables are required. The included tools let most owners open the speaker and exchange the cell in minutes. The upgrade is worthwhile when the original pack shows reduced run time, swelling or failure to charge. It does not add new features or increase capacity beyond the factory specification.

Questions about this item

Will the 3.7V 2600mAh pack power my Onyx Studio 3 the same way the original battery did?

Yes, this 9.62Wh lithium-ion pack matches the voltage and capacity specified for the Onyx Studio 3, so runtime and charge behaviour remain unchanged.

How can I confirm the PR-633496 is charging and holding capacity after I install it?

After fitting the pack, the speaker's charging indicator should illuminate normally and the unit should reach full charge in the usual time; playback duration at moderate volume should match the original 2600mAh rating.

Does the box include the PR-633496 battery and the free installation tools, or must I buy any tools separately?

The package contains the 3.7V 2600mAh PR-633496 battery pack and the supplied installation tools; no additional tools are required for the swap.
