I had no idea! Thanks. I thought once the batteries were dead, they were useless. Sorry for the bad info.
The reason why RFID can work "forever" is when they pass by a transmitter, such as the Mickey heads at the Park Gates, it sends a small electronic wave to the MB. That small electronic wave will physically pass by the circuitry in the MB making it "move" up and down and provide just enough power for it to transmit information. Inductive power.
Eventually it may not work, but that will be a long time.
