There is the risk of the magnet slipping and possibly causing a short.Why not just put a small earth magnet on the positive contact surface of the battery and give the 18650 battery a contact?
mine did not there is a ridge on the brass ring. i snipped mine off . it looks like its just pressed on there.
i put the 123 back in they work fine to with out the ring. im sure the ring is a safety piece ,but it sure seems fine .
