I have a Joyetech eGo-T 1000mAh battery I recently got from a friend of mine and recently I'm having an issue where if a tank is screwed into the battery (a tank in general) , the light stays lit after pressing it. It does not do this with a tank not on it, only when it's screwed in. I really like the battery so I don't really want to toss it, so I'm hoping the battery isn't toast but what can I say I got it for free
