Replacement battery for Onyx Studio 3
This 2600mAh lithium-ion cell is built to restore portable power to the Harman/Kardon Onyx Studio 3 speaker. It matches the original 3.7V specification and fits the internal battery compartment without modification. The part carries ISO9001, RoHS and CE certifications. Buyers needing a higher-capacity pack for longer run-time will not find it here.
Thermal and power behaviour
The battery operates at the nominal 3.7V used by the speaker's charging circuit, so heat output and current draw remain identical to the factory cell. No additional cooling or voltage regulation is required during normal playback or charging cycles. The certified construction meets standard safety limits for consumer audio devices.
Build integration
Physical dimensions of 69.26 x 20.40 x 20.40mm allow direct installation in the existing battery bay. The two-wire connector aligns with the speaker's mainboard, leaving all other internal components untouched. Users who require a different form-factor or a multi-cell configuration cannot use this single-cell module.

Questions about this item
How do I install the PR-633496 battery in the Harman/Kardon Onyx studio 3 and which step causes the most trouble?
Open the speaker cabinet, disconnect the old pack, match the 3.7V polarity exactly, then seat the 69.26 x 20.40 x 20.40 mm replacement; the step most often missed is aligning the connector key before pressing it home.
What maintenance or replacement will the PR-633496 need over time?
The 2600mAh lithium-ion cell gradually loses capacity; plan to replace the pack again once run-time drops below roughly half of the original 2600mAh rating.
What limit appears first when the Onyx studio 3 runs at high volume on this battery?
The 3.7V 2600mAh capacity ceiling is reached first, causing voltage sag and automatic shutdown before thermal limits become an issue.
