Easy to replace, great battery life.
Works great! My two Onyx 3 speakers were down to 30 minutes playtime. It took less than 10 minutes with each speaker to put in the new batteries. The screws on the Onyx 3 are standard Phillips. Iโve only tested one so far because after 5 hours it was still playing strong, I believe the second speaker will be just was strong. With the Onyx 3 the battery case screws are slightly shorter than the speaker case screws, just keep them separate.

Outstanding Replacement
This was a perfect replacement for a Harmon Kardon Onyx Bluetooth speaker. It has a larger capacity and requires a longer charge, but that is fine with me.
