I recently was dealing with a similar problem with my eGo battery charger for my 900ma battery. After exchanging it for a new one, and having the new one do the same thing, I finally figured out that if I plugged the charger into a different USB port, it solved the problem.
I guess some USB ports are able to output more energy than others? I don't know enough about how they work to say for sure, but I would recommend trying a different energy source.
