Over time, your beloved B&O speaker’s battery may deteriorate to the point of failure, leaving the device completely unresponsive—even when connected to a power source. This occurs when the aging battery loses its ability to hold a charge and essentially transforms into a power-blocking resistor. The solution?
Simply remove the faulty battery to bypass this electrical roadblock. Your B&O A2 will spring back to life as a fully functional wired speaker, ready to deliver its signature premium sound once again.

I had no idea you could convert my B&O A2 into a wired speaker by replacing the battery! It’s pretty clever how removing the old one restores functionality. I’m definitely considering giving it a shot if my speaker starts losing juice. Good to know there are ways to breathe new life into older tech.
I had no idea you could just replace the battery to revive an old B&O A2! That’s really helpful, especially since I’ve been thinking about picking one up. It’s great to know there are ways to extend the lifespan of these speakers. I’ll definitely keep this in mind if I ever need to troubleshoot mine.
