No power to camera, battery showing as charged?

Battery showing as charged on charger, but nothing when in camera, not even showing as an empty battery. Camera hasn’t been damaged and has been used recently. Battery was flashing continuously, then solid green (full charge). I’m worried that the issue is with the camera body. No spare to check at the min. Has anyone any ideas?
