If you purchased it from Apple , bring the MBP back.
If you did not purchase it from Apple, make certain that the connection is properly seated.
Then try a SMC reset:

If no success, you may a victim of an inferior Apple battery knock off. Contact the vendor for possible relief.
The only sources that I trust for MBP batteries are Apple and OWC:
