I need help with battery

Battery Replecment iOS not calibrating

I replaced the battery about two week ago. Have cycled this battery many tines, but I can’t seem to get iOS to calibrate. When the phone dies, it’ll try and reboot on the dead battery. Also the Battery Health feature (iOS 11.3 Beta 4) is saying that my battery health cannot be determined ever since it’s been replaced. So what is going on? I was going to just put the old battery back in to see if iOS would read the health
