My new battery for the MacBook Pro 2015 won’t charge after replacing

Hi everyone,

So I recently replaced my very old battery with a new Green Cell one. I thought it went smoothly and left it to charge overnight after installing. However, when I turned it on this morning it seemed fine before immediately dying once I removed the charger.

after looking online I have tried to reset SMC, PRAM, I have removed the battery and then connected the charger, putting the battery back in and still nothing seems to work.

I have attached the coconut battery picture so you can have a look, it all seems to be fine.

any recommendations is really appreciated.
