No it doesnt. I will look In to replacing battery. I got a lot of great use out of the headset so no complaints here. I did notice on a two up ride that it didn’t last 10 hours like it normally would.Yep this says diminished capacity in the battery dept. to me. The output of an Li battery is pretty flat until its empty. When you charge it does it charge quickly? Like really quickly? Another indication that its capacity is a shadow of its former self.
