This is Not an Option.

About Battery Degrading:

Batteries degrade as they are used, eventually depleting (which you should avoid). It cannot stay at 100%. I have had mine replaced a few times, due to high use. I do not use it as much at this moment in time. So, I have not had to replace it in a while. Unfortunately, there is no way to know how nor when this degrade occurs. Apple recommends that you get a new battery when the Battery Health reaches 80%. So, there is no need to change the battery, all is fine.
