MacBook Pro 2013 not recognizing new battery shortly after install.

The Ifixit guide rated battery replacement for this laptop "very difficult" so I paid an experienced but unauthorized Mac repair guy to do the job. The battery seemed fine at first, but then the Mac didn't recognize it. Coconut verified this information. The repairman deflected the blame and said that it must be because of a bad motherboard. Suggestions? Might it be the battery connector?

Let’s get a better view of things, post a screen snapshot of CoconutBattery and post it here for us to see Adding images to an existing question

Make sure the charger is plugged in. It could be a bad battery or the MagSafe connector is dirty or damaged. Then the MagSafe charger could be a knockoff which tend to damage the logic board comparator logic which is very repairable!

I added the Coconut screen capture to my question. The laptop works fine with the power plugged in, but will not react at all when the Magsafe is disconnected. I suspect that the battery is holding a charge, but not discharging -- after many hours disconnected, when plugged back in there is no need to reboot as the login screen returns quickly.

@urbanshaman - Sadly you have a bad battery, contact the iFixit store to get a replacement.
