Shutsdown randomly after replacing battery

Hello I have bought a Battery replacement for the MacBook Pro 13 early 2015 model.

I followed the steps on fixit video and successfully replaced the battery. Using the device for a long period I have come across a problem, all of a sudden my laptop shutsdown randomly. It seems that it shuts down often after going below a % below 40-50. I have searched on fixit forum and seen on apple website that you have to reset smc to solve power/battery issues. After doing that I thought it had worked, but got the problem again. Please if there is a way to fix this problem let me know or change battery. I need this laptop as I use it every day. I have send a screenshot of coconut battery.
