If I show available range as "Rated" (in the US, anyway), I believe this to show, based on a certain energy usage rate, how much energy is in the battery. Now, if I switch to percentage, what is the percentage showing? Is it showing percentage of original capacity, or percentage of available capacity? In other words, if I have a 5% degradation in the capacity of my battery, will it charge to 100%, or just 95%? Presumably the rated range would show the degradation (or else I would never know it's happening), but is it reflected in percentage as well?
