I see that you're using the USB to your laptop. Do you have an AC adapter? I would not charge a battery on my computer overnight while I'm sleeping without some form of protection for the battery just in case something happens.

It is very possibly a bad unit. I would contact the place you bought it from and ask for an exchange.

Hard to say from what you are describing. Are you charging it from a usb port? When you click it 5 times, are there any lights flashing on the battery? It is pretty hard to push the center pin down on the battery with one use. It usually will happen after several uses. You don't need to screw on the CE4 so tight for it to make contact. It sounds like the battery is bad, not the CE4. What kind of battery? There are many that come with a blister pack. I would take it back to the supplier.

CE4 is the tank portion (clearomizer), and the battery portion (eGo-style) is the issue.  After charging for 3-4 hours, it should be fully charged.  Either you have a defective charger, or the battery is not capable of holding a charge... it happens, even with a "new" one... you can't tell by looking at them if they are bad.
Take it back to the store and let them know it won't charge and they should replace it, no questions asked... unless it was bought at a flea-market or similar type venue.
Also, what is the brand-name of the kit?  Is there any markings, logos, or identifying marks/labels on the battery?  Knowing  what the brand is will really help out.  Even no-name brands can be quite reliable, but you can get a bad one even from reputable brands like Joyetech, Kangertech, Aspire, and Vision.

CE4s have been around for a number of years. Anyone who has been vaping for at least three to four years would have had one.
Can you take a picture and post it here for us to see what battery you have? That might give us some more information with which to help you.
