This is correct.
It was replaced by the K6 when Mercury battreies (which the K3 uses) became illegal.
However. there are now expensive non-Mercury batteries available of this size.
But please note that the K3U can also be phantom powered - you can cut a short section from dowling to use as a dummy battery - dummey battery was only really needed on the earlier versions, it helps keep a good contact between the capsule and powering module.
