Maximum Capacity, Cycle Count

All batteries inevitably and inexorably degrade, and all inevitably fail.

The degradation is also not linear, and the value shown for the current health may or may not follow a predictable pattern over time.

For details from Apple, see this article ➡️ Determine battery cycle count for Mac notebooks - Apple Support

…and ➡️ About battery health management in Mac notebooks - Apple Support

More relevant for most folks is whether the battery lasts as long as is needed, wothout an “extra” recharge becoming necessary during normal usage.

thanks Mr Hoffman its only six month old, should I leave it plug in all the time?

You can leave it plugged in when convenient to do so. Leaving it plugged in will not damage your computer or battery. Leaving it plugged in reduces the rate of accumulation of battery cycles.

thanks bob so nothing to worry about Maximum Capacity 97%?

Batteries degrade. Just like our bodies degrade. Though swapping a battery in a MacBook Pro (if this case should eventually come to that) is a whole lot less messy, and less costly than swapping the degrading parts within each of us.

Batteries degrade over time, use, environmental conditions, etc. It's perfectly normal

It's normal.
