I am trying to understand the condition of a battery on a 2008 Roadster I am hoping to purchase from a private seller. As background, the car has about 3,000 miles but no warranty. I am working on getting service records, but other than the battery questions below, all indications are that the car is in great shape. I am confused about the information I have gotten on the battery from the seller. My confusion stems from the different charge modes of the Roadster that the seller has given me screen shots of (see below). I did try researching different modes, but I am still confused. Some help would really be appreciated! Here are the screen shots: (I was told the battery was between 95-98% SOC) First: Range Mode - Ideal setting - 208 miles Second: Range Mode - Estimated rate -146 miles Third - Max Range mode - Ideal setting - 233 miles Fourth - Max Range mode - Estimated rate - 164 miles. My main question is do these readings reflect a Roadster with a healthy battery at 6 years, 3,000 miles. Does the 233 reading in "max range" mode simply get compared to 245 miles a brand new Roadster would have gotten fully charged in range mode? Is it more complicated than that? Is it the 208 mile "Range mode Ideal" reading that really gets compared to 245 miles for a new Roaster (I'd never heard of "Max Range" before getting these screen shots, and I'd never heard of anyone describing two different readings over 200 miles). Is there anything inconsistent in the four readings in the pictures emailed to me... if anyone is willing to take this on, an explanation of the four readings would be appreciated. I am interested to hear what people here at TMC think. I realize I could pursue this question with Tesla service (and I am trying to do this) but there is a complicating factor with that so hearing from your experience would really be appreciated.
