Tesla Roadster Survey Form

Tesla Roadster

The purpose of this survey is to allow Tesla Roadster owners to share their experience with battery pack capacity and how it changes over time and distance driven. If you are a Roadster owner, please contribute your experience to the survey by filling in the information below. You are welcome to enter data again as you increase your time and distance.

If you have previously entered a report on this vehicle, use the Roadster Battery Survey Update Report

Before you start, you may want to go collect several bits of information from your car.

  • Current odometer reading
  • VIN sequence number
  • Assembly date
  • Ideal Miles/Km after a Standard and/or Range mode charge

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.

Your Battery Pack and PEM

Notes: If you see a range of values, please enter the average or most common value. If you haven't read a value recently, please leave it blank or wait until you've made a reading to submit. If you haven't done a full range mode charge recently, next time you do, you can use the update form to add the range mode number to your report.

Please enter your ideal range after a:
Full Standard Mode Charge: ideal miles
Full Range Mode Charge: ideal miles

Another measure of Roadster battery capacity is called CAC, a value in amp-hours (Ah). Tesla service technicians can read this value from the ESS service screen. We have been told this is the best measure of your battery's capacity. If you have a recent reading of this value, please enter the value.

CAC: Ah (a US-format decimal number like 123.45; leave blank if unknown)
