Smoktech Tumbler Problem! Complicated... looking for a resolution.

[Indikah]

So I'm brand new to the forums here. I've been lurking since I started vaping in January. I'd post to a tank specific subforum but as a new user, I can not. So here is my issue... please bear with me. It's slightly confusing.
I have two Smoktech Tumblers. I have two ego-T 900mah batteries.
Both tumblers work on one of my batteries. So there is no issue there... If I had only that one battery, I'd assume nothing was wrong with either of my tumblers.
However...
Only one of my tumblers work on the other battery, but this battery connects to all other tanks I have tried, including my boyfriends.
Again, the tumbler works with every other battery, and every other tank works with that battery.
Could someone give some insight on how/why this is happening and how/if I can fix it?
I should mention that both tumblers are fairly new purchases, within the past few weeks. The batteries are maybe a month old.

Sounds like it could be the pin in that battery or on that particular tank are just slightly off. Carefully pull the pin in the battery up just a little with a toothpick or paperclip and see if that helps.

Before you do that with your battery, try pulling the center pin down on the bottom of the tumbler, grab it with tweezers or needle-nose pliers and just pull it down slightly. Don't pull it too far though, because then it'll cause more problems than it solves.

If it doesn't work, you can try to gently pry up the center post of the battery as the above poster mentioned.

Sounds like the center post on the battery has been pushed down some...just enough that it is not connecting to this one tank. I would try prying up the center post just slightly. This is a rather common problem when something is not firing. A tiny screw driver, safety pin, anything that you can get in there a wiggle that center post up just a hair.

Wow, everyone beat me to that answer...that confirms that I'm a really slow typist.

Thanks for the replies! I'll give it a shot.

Edit: It worked! Thanks again
