3000mAh ICR22650, 22650 Battery Replacement Compatible with Harman Kardon Onyx Studio 4 Wireless Bluetooth Speaker

My Studio 4 speaker started to have static when playing unless it was plugged in. I watch a youtube video on how to replace the battery. I just got done putting the battery in and now my speaker doesn't have static when running on battery power. The battery is the exact same size as the factory battery. It fits, you just have to work with it. It's crazy that Harman Kardon said that they don't replace the battery and that the speaker couldn't be serviced. They offered me a 20 percent discount on a new speaker. I will not be buying any more of their products.

Watched a video on youtube to install, very simple. Nice to have the HK speaker back to full strength when not on charger!

Now my HK Onix is not sealing properly because of the tight tollerance and the bigger size of the battery. 2 screaws strapped and now what used to be a reasonable sounding portable speaker became a rattling device...

Working good

This battery does not have the capacity of the original battery. The original battery would give me 6 to 8 hours of playtime this one tops out at about 1 hour. Also drains itself if not left plugged in charging.

Funcional

Product came as seen on picture and works great.

Do not buy this replacement battery! Changed my original battery with this one, this one only lasts 5 minutes. Will return soon. Plus it did not come with the other accessories.
