Reading "Battery Not Installed" and No battery Icon

I have a late 2012 13” Macbook Pro Retina. It was charging 53% after replacing the battery 3 years ago with then an after-market battery. I think I ordered it from iFixit.

If the power cord was disconnected, it completely went dead. When the power adapter was plugged back in it took a few seconds to log on and then operate only from the power adapter while not charging.

I thought it was the battery with a typical 3-year lifespan, and ordered a Powerwoo battery from Amazon which I installed myself. The process was simple.

After installation and checking the computer information it read "Battery Installed: No". Also, the battery icon disappeared from the computer which is logical if no battery is installed it appears.

When I checked Amazon reviews of Powerwoo it is overall believed to be a good replacement battery, however, one customer reported that the after-market battery did not work on the same type and year computer as mine.

Amazon refunded me the $44.

What may be the possible problem? If I order a battery from you will it work if the battery is the problem?

I don't think it's the logic board because I am able to pull up my documents, pictures, etc., etc., and everything of mine on the computer.

However, I read that a bad logic board can cause a battery malfunction. I did an SMC reboot several times. The light blinks green, then stays orange but again is not charging and reported after the Powerwoo installation, "Battery Not Installed."
