Replacement Battery for Onyx 4 Speaker

This Cameron Sino battery replaces the original power cell in Harman/Kardon Onyx 4 and Onyx Studio 4 speakers. It delivers 3000mAh capacity at 3.7 volts with 11.10Wh energy rating. The unit is built for owners who need a direct swap when the factory battery no longer holds charge.

Certified Build With Protection Circuitry

The pack carries ISO9001, RoHS and CE certifications and includes overcharge, over-discharge, over-voltage and short-circuit protection. A fully decoded chip communicates with the speaker exactly like the original component. Dimensions are 68.30 x 23.60 x 23.60mm and weight is 70.8g, matching the OEM form factor for a secure fit inside the cabinet.

Low-Heat Operation In Normal Use

Lithium-ion chemistry runs cool during typical playback and charging cycles, adding no audible fan noise because the speaker has none. The protection circuit limits current spikes that could stress the cells. Storage above 60°C is cautioned against by the manufacturer to preserve long-term capacity.
