How long does a battery last?
Inside each beacon is a non-rechargeable lithium battery that should last up to 2 years. Yes, the Bluetooth is really low energy. If the battery is running out of power, you’ll be notified. You don’t have to worry about changing it, because in two years time you’ll probably get your hands on our new much more advanced Beacons.

So apparently now it’s cool to announce that you are expected to replace a product before its battery runs out. At least the other guys are subtler about it.
I won’t bore you with the details, but if you’re having trouble pairing an Apple Wireless Keyboard and you might have paired it in the past to more than one computer/tablet/phone try pressing the “play/pause” or volume keys. If something starts playing music, unpair that first.
It might save you embarrassment after half an hour of doing the power button pairing dance.
