macOS Catalina 10.15.5 has a new Battery Health feature. Apple has created a lot of fanfare about this new feature which seems a bit over-hyped to me. If you are using a newer Mac Laptop with a T1 or T2 chip, the Battery Health feature will be available. If you are using an older Mac Laptop, you are out of luck. This article explains how the Battery Health feature works. By the way, if you DO have an older Mac Laptop, then go get the really excellent App Cocounut Battery. The Pro version of Coconut Battery costs a few dollars, but it has way more information than Apple’s Battery Health feature.
