Direct replacement for Onyx Studio 8

This Cameron Sino battery replaces the Harman/Kardon ICA077NA cell inside the Onyx Studio 8 speaker. It uses nickel-zinc chemistry at 3.7 volts and 3350 milliamp-hours, matching the original specifications. The pack is certified to ISO 9001, RoHS and CE standards.

Capacity and voltage match the original

The single deciding specification is the 3350 mAh capacity at 3.7 volts, which equals 12.40 watt-hours. If your speaker requires a different capacity or voltage this cell will not be compatible. A fully decoded chip ensures the same communication with the device as the factory battery.

Low heat and stable output in normal use

Nickel-zinc chemistry runs cool during typical indoor playback and the built-in protection guards against over-charge, over-discharge, over-voltage and short circuit. The 54.0 gram pack fits the original 71.00 by 20.00 by 20.00 millimetre cavity without forcing the enclosure. Expect normal operating temperatures and no audible noise from the battery itself.

Questions about this item

How long will the 3350 mAh capacity actually run my Onyx Studio 8?

The 3350 mAh rating matches the original specification; real-world playtime depends on volume level and audio content but will be equivalent to a fresh factory battery.

What does the 3.7 V nickel-zinc chemistry mean for charging and safety?

The 3.7 V nickel-zinc cell uses the same voltage and connector as the original, with built-in overcharge, over-discharge and short-circuit protection for safe operation.

Will the 71.00 x 20.00 x 20.00 mm dimensions fit the Onyx Studio 8 battery compartment?

Yes, those exact dimensions and the 54.0 g weight replicate the original pack, so it slots into the speaker without modification.
