My laptop(Acer E5-573) Shuts down itself at 85% and starts only if plugged in.

My laptop is nearly 5 years old and its battery was dead so I got a replacement for my battery and it worked perfectly fine for 6-7 days and then later the laptop just started shutting down itself not even showing the shutting down screen and the fact that it does not even turn on unless plugged in and after its plugged in and turned on it shows that its at 87% sometimes 90% and battery is real because I checked each and every word of the old and the new battery and it was fully same. I am attaching a pdf containing my battery report.

The replacement battery is defective according to the battery report. It has already lost more than 50% of its design capacity. Return it to the vendor ASAP for a replacement. Jack E/NJ
