I’m unsure if you can replace battery’s on them, but it sounds like you’re doing something wrong here because I’ve owned the megaboom 3 and hyperboom for over 2 years each and can let both of them play morning to night and neither battery will die..
Sorry, there was a problem. Please try again later.Hey there Dbd67. Unfortunately the Hyperboom battery can not be replaced. I would recommend contacting us via our support site for assistance with battery issues. -Weston from Ultimate Ears.
