I've got a Vapor Titan Short Automatic battery acting really strange. It takes a charge, but when you plug it into the charger, the light does not blink. Then when you screw it to a tank or cartomizer it immediately starts heating the liquid. When you take a pull off of it, it seems to stick in the activated position and keeps heating the liquid for about 20-30 seconds. The LED does not come on until after it is done heating. Then when you unscrew it from the tank, it blinks 2 or 3 times like its dead but it's still charged. I've tried setting and cleaning the posts but nothing seems to work. This Battery is only about 2 weeks old. Any suggestions?
