New battery for macbook pro m1 chip 2020

Here you go: Check the condition of your Mac notebook’s battery - Apple Support

Typically there will be a "Service Recommended" message in the battery status, but the most common reason is when the battery health has dropped below 80% of nominal new. It could also happen if a battery fault is logged. I had that happen when the battery management system was corrupted (it was reporting negative battery capacity).

When the battery does not perform to your needs. This will occur sometime after the Battery Condition becomes "Service Recommended".
