Hello, I am having an issue with my new xl 900mah maual battery and clearomizer. I have tried out two of the four clearomizers. I fill them tilted as instructed without issues of touching the center hole. I fill them below the top black line about the second line from the top. I make sure both ends are tight. The first evening everything was flawless. By the third evening I unscrewed the clearomizer and notices a drop on my battery. Every time I vape now I unscrew to check and I notice a drop or a little moisture on the battery. I am worried about ruining my battery. Is this normal????
