The Rated Range in my 6-month old SR+ is now about 237 when warm ambient and about 227 when cold (<30 degrees F). So charging to 85% when warm gives me a little over 200 miles rated range, but 85% when cold gives about 193 miles. Is charging up to, say, 100% when cold as detrimental to the battery as charging up to 100% when warm? Are the cells getting up to the same voltage when cold as when warm? Or, since the Rated Range is less, is charging up to 100% when cold easier on the cells. I'm asking because I'm wondering if charging up the the same Rated Range regardless of temperature has the same effects on the longevity of the battery.
