Take it back to the shop that you got it from and ask for a refund.

Batteries can be compromised by dirty Contacts both in the Camera and on the battery.

you can confirm dirty contacts by inserting and removing the battery several times fairly quickly.

if this works the Battery indicator in the Viewfinder and or on the Monitor

see page 6, 8, 28 in the D5000 Manual

should change from near minimum to near maximum

Contacts on the Battery may be safely cleaned with a pencil eraser making sure any residue is removed from the battery

a pencil eraser may be used to clean contacts inside the Battery compartment but the residue will be harder to remove get a Rocket blower or similar to use air forced through a bulb to clean this area and any lenses of course

It sounds like you have a dead battery. Sometimes batteries are defective… Even if new. If they won't replace your battery or camera (which they should) you can get a battery online here:
