    high quality replacement

Fits perfectly into HK Onyx. Make sure your unit takes the long rectangular battery though as some take a round battery.  installation was fairly painless.

*by A***R on Reviewed in the United States on October 16, 2020*

I bought this battery for my harman kardon onyx bluetooth speaker, and all i got to say is dont buy this product.  It doesn’t hold the charge.It took 5  hours to reach a full charge. After that i removed the charger And i had to leave home for 1 day. And when i came back i tried to turn on the speaker  but it was dead.First i was confused and thought maybe i did something wrong.  So i charged it again and i left the speaker off for a whole day just to see if it will hold on the charge.and again the speaker was dead when i tried to turn it on at the end of the day.Such a waste of money for this low quality battery.
