Measuring Battery Capacity
To get a good reading of you battery capacity, you need to read the "Ideal Range" (not Estimated Range) from the charge state screen after waiting at least 10 minutes after the charge has completed. The reason for this is because often the value shown immediately after charging has completed is inaccurate. In the 10 minutes following the end of a charge (or drive) the Roadster takes additional measurements from the battery pack to calculate a more accurate estimate of the pack's stored energy.
