This may be a question for @len. Does anyone know if there is a way to test the battery levels of old MagicBands? Going in September and my DS6 wants to wear one from his last trip in 2016, but my guess is that the battery will be dead. Would hate to wear it only to get to the park and have it not work. I thought I read somewhere that it would likely work at tapstiles, just not be strong enough to pick up the RFID from afar for ride photos.
I didn’t know if you could take one to guest services and they could check it for you.
