Replaced both my HKS4 with the new batteries and first of all they’re smaller than the original battery so they rattle loosely in the holder and second it’s been a month since I’ve installed them and now both my speakers don’t even last an hour before being completely dead. Mind you I only ever play music at half the volume and have consistently used them for 2 weeks. Pay the extra $ for better quality people.

Didn't even last 6 months.
Got 7.5 years out of the original Onyx 2 batteries. Got less than 6 months out of these garbage replacement batteries. Don't waste your time.
