Dead battery? That's a matter of perspective! Instead of recycling coin cell batteries when their time is due, I will put them to good use and show you a secret feature of a Raspberry Pi Pico - and what sets it apart from other microcontrollers. Let's use the dead batteries to check for dead batteries, so I never have to doubt the battery again! I'll end up with a nifty box to keep my batteries organised, tested, and ready to use!
