Well, first thing you want to do is consider ordering from a certified eGo supplier, preferably one of the suppliers on the ECF website, because there are lots of flukes that look just like the official ones in stores. In the meantime, try charging for a couple of hours, and make sure all the parts are screwed on tightly, but not too tight. Cleaning it would also be a good idea. Also take a look at your tank and make sure it's working properly. You haven't given any details as to what model, tank, and so on. There are hundreds of eGo batteries and thousands of tanks, and just saying it's eGo isn't much help, so giving some more details would help.
