Battery not charging, condition replace now

Here you go: About Mac notebook batteries

• Replace Now: The battery is functioning normally but holds significantly less charge than it did when it was new. You can safely continue using your computer, but if its lowered charging capacity is affecting your experience, you should take it to an Apple Store or Apple-authorized service provider.

Then, follow Servicing the battery in your Mac notebook.

"Replace Now" battery condition means the battery is worn out and needs to be replaced. If at all possible have Apple replace the battery for you since the quality of third party Lithium-ion batteries is extremely poor even when purchased from a reputable vendor.
