Did you do a SMC reset and the cycle the battery at least two times?

No, didn't know about those tricks. Will have to try.

What is SMC reset? Thanks for your response.

Where did you get the battery from? If it was iFixit, duds are unusual but you probably got one. If if it was from a 3rd party, you might want to steer clear of those.
