Kent is almost certainly right.
However, your situation has piqued my curiosity. I wonder whether they would work on an HV
mod? I don't currently have one, but when I did, I found that sometimes my tired old attys would revive on it. Also, "HV" atomizers are deliberately designed at 4.5 ohms for the purpose of using at 6V. Hmm.
But no, don't hold your breath. If you have an HV mod (or know someone who does), you might want to try it. Otherwise, introduce those attys to your wastebasket.
