Direct replacement battery

This 3400mAh lithium-ion pack replaces the original LI11B001F cell inside Harman Kardon Onyx Studio 1 and Onyx Studio 2 wireless speakers. It restores portable playback when the factory battery no longer holds a charge. The 3.7V 12.58Wh rating matches the original specification. Buyers who need a different form factor or higher capacity should look elsewhere.

Upgrade from depleted original

The swap is worth it when runtime has dropped noticeably or the speaker shuts down at moderate volume. A fresh 3400mAh cell returns the runtime the speaker delivered when new. If the speaker fails to power on for reasons unrelated to the battery, this replacement will not fix the problem.

Simple user installation

The package includes free tools to open the speaker and disconnect the old pack. No soldering is required; the connector plugs directly into the existing socket. The most common issue is forcing the connector the wrong way round, which can bend pins. Take care to align the plug before pressing it home.
