Harman Kardon Onyx Studio replacement battery

This Cameron Sino unit replaces the original cell in Harman Kardon Onyx Studio 1 and Onyx Studio 2 portable speakers. It uses high-quality cells built to meet or exceed the manufacturer specifications for capacity and safety. The pack restores full wireless playtime so the speaker performs as it did when new. Installation is straightforward and does not require specialist tools.

Check speaker model and battery access

Verify that your speaker is an Onyx Studio 1 or Onyx Studio 2 before ordering; other models use different packs. Confirm you can open the battery compartment, which usually involves removing a screw cover or base plate. Have a small Phillips screwdriver ready and note the connector orientation before disconnecting the old cell. Ensure the speaker is powered off and unplugged from mains before starting the swap.

Thermals and power behaviour

The replacement chemistry runs at the same voltage and current as the original, so heat output during playback and charging remains unchanged. Under normal listening volumes the pack stays barely warm and the speaker’s fanless design stays silent. Charging follows the speaker’s built-in controller, drawing only the current the original circuit allows. No extra cooling or higher-wattage adapter is needed.

Questions about this item

Does the Cameron Sino battery for Onyx Studio 1 & 2 include any tools or adhesive strips for the replacement?

The package contains only the replacement battery itself. No screwdrivers, pry tools or adhesive strips are supplied, so you will need to provide those separately if the speaker requires them.

My speaker is an Onyx Studio 2 — is this the only compatible version or are there capacity choices?

This is a single-specification battery built to match the original Onyx Studio 1 and 2 cells. No alternative capacities or revised versions are offered for these models.

What does “meets or exceeds original specifications” mean for actual playtime on a full charge?

It means the battery delivers the same voltage and capacity as the factory pack, so you can expect the original rated playback time — roughly eight hours at moderate volume — once the new cells are conditioned.
