Try installing the battery in another like system if you can. Does it react the same way? If you don't have access to another system to do this. Try running AHT to see if it finds something.

I suspect you have some other damage on the logic board or the battery is defective. Did anything leak out and get on to the logic board?

No visible damages to logic board. nothing has leaked from the original battery, Ryan from ifixit is going to send another battery so perhaps the 1st new replacement has a problem in it , I will know next week
