Has anyone been using this replacement battery for more than a year? Is it holding up well? Does it hold a charge well after a year or 2 of use?

Don't worry! Until now, we have never received any complaints from customers about the performance of battery was deteriorated gradually after one year's use.

Will the charger for the 2600 work with the 3500?

If the batteries are the same style(work for Harman/Kardon Onyx Studio or Onyx Studio 2), the charger can be used for 2600mAh battery or 3500mAh battery. Please feel free to contact us if have any future questions, thank you!

Would this work on a Studio 3?

We have received responses saying that the battery can work on Studio 4. We can assure that it can work on Studio and Studio 2, but Studio 3 we cannot be 100% sure of the compatibility.

Is this the most powerful, longest lasting best battery available for the hk onyx studio 4 bluetooth speaker please?

Sure, our battery uses the same material and craftsmanship as the original battery. As long as you carefully replace it according to the video on YouTube, you will get a new speaker. If you have any problems after purchase, you can also full refund or replace it at any time.
