Cameron Sino 350mAh Battery for Beats Solo 2.0 3.0

This replacement battery fits Beats Solo 2.0 and Solo 3.0 wireless headsets. It uses a lithium polymer cell rated at 350mAh and 1.30Wh with a nominal voltage of 3.7V. The pack includes a fully decoded chip that matches original specifications.

Practical limits of the lithium polymer cell

Capacity is fixed at 350mAh so runtime matches the original factory specification. Operating temperature must stay below 60°C or 140°F to avoid damage. The physical envelope measures 33.94 x 34.88 x 3.64mm and the cell weighs 7.4g.

Installation notes and common pitfalls

Installation videos are widely available and the process is straightforward for most users. The connector must be seated firmly or the headset will not power on. A new cell reaches full performance after two or three complete charge cycles. Avoid low-quality chargers to preserve lifespan.

Questions about this item

How do I confirm this battery fits my specific Beats Solo model?

What runtime can I expect from the 350 mAh 1.30 Wh capacity in daily use?

The 350 mAh cell at 3.7 V stores 1.30 Wh, matching the original battery's energy rating so playback time should be equivalent to when the headphones were new.

It includes a fully decoded chip and connector designed to plug directly into Beats Solo 2.0 and Solo 3.0 headsets without adapters or soldering.
