Review: No issues - Worked perfectly Review: Harmon Kardon Onyx Studio 4 battery replacement - My battery in my studio 4 was completely fried, the speaker would not function unless plugged into the wall outlet. I decided to grab a replacement battery after browsing on desertcart and realized there were not many reviews on the batteries listed. This is a perfect replacement for the onyx studio 4. The disassembly of the speaker itself is not very hard to do by any means, especially with plenty of videos on how to do so on YouTube. The battery swap took less than 15 minutes total, and it worked flawlessly! This battery saved my speaker and made it fully functional again. Extremely happy with my purchase.
