## Customer Reviews

### ⭐⭐⭐⭐⭐ Best replacement Harmon Kardon
*by F***K on June 24, 2021*

This is the best duplicate of a original battery. This is my 3rd time replacing my battery in my studio 4 & this one is by far the closest to spec of the factory battery in the HK unit. The foam vibration damping material around the ends of the battery fit snug in the compartment inside the speaker & so far it’s holding a charge fairly well. I brought mine to the beach laying in direct sun & it played for about 5 hours on 1/2 volume. This is a 3000mah - 3 amp hour battery, so 5 hours of constant music in 100 degree weather is a pass in my book. Buy this one.

### ⭐⭐⭐⭐⭐ Harmon Kardon Onyx Studio 4 battery replacement
*by M***T on April 27, 2021*

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 Amazon 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. Shipping took less than 2 days

### ⭐⭐⭐⭐⭐ Better than Factory Original
*by S***R on May 6, 2024*

Bottom line: fits perfectly with no rattles and the battery life seems like it's 20% more than the original battery. I have two Harman Kardon Onyx Studio 4 speakers and the battery on one of them stopped holding a charge. I replaced it and the charge on the new battery seems to last 20-25% more than the original battery in my second speaker. The second speaker is perhaps 2 years newer than the one whose battery I replaced and it seems to not have lost any of its charge longevity. Thus, I think it's a fair battery comparison and I recommend this battery replacement for the Studio 4.
