Macbook Pro 2012 shuts down unexpectedly with good battery

My MacBook Pro 2012 will suddenly shut down when the battery level will show 58% or something similar. I have checked the health of the battery and it indicates it is normal - no need for service. I have 120 of 500 GB available. I am running macOS Catalina 10.15.5. Suggestions?
