LR atty's won't fire when on ego batteries a lot of the time

[Valhalla1]

I'm having a really weird problem with my LR attys and ego batteries. I have 4 ego batteries that all are doing the same thing - when I have a batt die and go to switch my atty to a different batt, when I assemble the damn thing I get no vape, no firing at all. I try switching the atty around to all the batteries I have and it won't fire

screw it into my 3.7v passthru, and I get plumes of vapor... the atty works fine. I just have to keep screwing and unscrewing it from different ego batts until finally it fires up and starts producing vape again. Then, I am fine and can use the ego mostly flawlessly until the battery dies, and then I'm back to square 1, screwing and unscrewing batts until I finally get one firing again (although sometimes after dripping 2 drops it stops firing again until I disassemble/reassemble it)

like I said its not the atts because at any time during this I can hook it up to the passthru and it works fine. also brand new attys do it too, not firing on the ego batts until it randomly does

cleaning the threads doesn't help. this didn't used to happen but now happens on all my batteries and all attys new and old

Is the eGo a Manual or Automatic version?

manual batteries, all 4 of mine do it. I've tried cone on, cone off. t-tip on or off, when I finally get it firing will usually keep working at least a few minutes before stopping
guess I should order a couple new batteries and see what happens

It sounds more that it's the atty that makes bad contact, try to pull that round thing of your atty to pull up a bit ,on the battery side of your atty.
