I am considering the purchase of a used roadster. I think I can test the "normal" health of the car.
But the most critical component to test is the battery, as a replacement would be quite expensive. The milage of the car is only helpful if the owner was responsibly treating the battery.
Can you clue me up what I need to test in terms of battery health. I make an educated guess that total capacity is proportional to battery health as far as a novice can test? So charge in range mode and see what it holds? So what was the total capacity when new? Does the car show capacity or only miles worth of charge?
Thanks for your help.
