Charging percentages off #23

If I want to charge to 80% I need to instead set the limiter to 77%, otherwise it will go over 80.

It appears each charge % level requires guessing and trial and error to find out what to actually set the limiter to to hit the wanted target charge.

What's happening is that macOS does not display the exact battery level on the status menu indicator. It is usually +2/3% higher than what it truly is. You can check by using a different battery monitoring app such as coconutBattery, which will show you that the percentage you set is where it actually stops charging.
