Replaced battery from iFixit in December, already showing Service

I replaced my battery in December from iFixit. I had followed the battery calibration procedure before using it. But battery has been losing charge pretty quickly. macOS says ‘Service Recommended’. Attaching screenshot of coconutBattery. What could be the issue? Also i am using a replacement charger and it gets extremely hot.
