Hiya Joseph!
Welcome to planDisney and thanks for coming by with your question. I especially love the tech questions because I'm a tech geek and have been using my MagicBand+ ever since the
Disneyland Resort began supporting them in 2022! They come in so many cool designs that I now have multiple Bands from which to choose for my trips.
To research your question, I happened to have a new-in-box
MagicBand+ from my last visit. I opened it but there was no documentation in the box regarding a two year battery life. The MagicBand+ comes with a rechargeable battery and the only downside to leaving it sealed in the box for too long is that you'll have to immediately charge the battery with the included charger cable.
What I suspect you might be referring to are the older MagicBand types which are not currently supported at the
Disneyland Resort. MagicBand 2 was announced for the Walt Disney World Resort in 2016 and those Bands had a non-replaceable battery with an estimated lifespan of about two years. With the introduction of MagicBand+ and a rechargeable battery, this is no longer an issue!
Joseph, I hope that answered your question. So go ahead and open that MagicBand+ (or are you keeping it as a gift for someone?) or shop for a new one on
disneystore.com! If you think of anything else, feel free to write back to us again! I'm always here for the tech gadgets and questions. We'll see ya real soon!
Wishing You a Great, Big, Beautiful Tomorrow!
