Sometimes your battery may act like it is not charging. This is due to the floating post in the center of your battery. One part of maintaining your Vapornine Nebula battery is to adjust this post at times. It is best to use a non metallic item small enough to fit between the center post and outside ring. As a last resort a small screwdriver for glasses will work.
If you look closely there is a rubber gasket between the post and outside ring, take a toothpick or your small screw driver and gently place it in between the center post and outside ring, pry up gently on one side, then turn the battery and pry up the other side to make the post go back to the center. You may have to do it a second time but this generally fixes the issue.
