Replacement Battery for Onyx Studio 8

This nickel-zinc cell is built as a direct replacement for the Harman/Kardon Onyx Studio 8 speaker. It matches the original 2600mAh capacity and 3.7V voltage so the portable speaker runs for the same duration between charges. The pack is aimed at owners whose factory battery no longer holds a useful charge.

Dimensions and Connector Fit

The pack measures 71.00 x 20.00 x 20.00 mm and weighs 51.0 g, matching the original mechanical envelope. A fully decoded chip communicates with the speaker exactly like the stock unit, allowing the onboard fuel gauge to report remaining capacity correctly. The connector orientation is identical, so the battery slots into the compartment without modification.

Thermal Behaviour and Protection

Nickel-zinc chemistry operates at modest temperature rise during typical indoor playback volumes. Integrated circuitry guards against overcharge, over-discharge, over-voltage and short-circuit conditions, limiting stress on the cells. The pack is certified to ISO9001, RoHS and CE standards, confirming baseline safety compliance for consumer use.
