nikon d700 problem

Hi I have problem with my Nikon D700 body
Camera won't power on just get the blinking low battery alert ?
I was try to use battery grip Meike the problem appeared after connecting and stay.

Kind Regards

I would take off the third party battery grip, and buy a used OEM grip(they run about $100). Also I would put a recharged battery in the D700 to make sure it will work without the grip.
I have no trouble with my D700 and Nikon OEM grip. So hopefully you can get yours back to working great again. You have my best wishes.
