Is it true that Tesla should replace a battery if it is no longer meeting 70% of its advertised range? Is this written anywhere? The Hawaii SC tech says he has never heard of this and has no idea what I'm talking about. Has anyone had any luck getting a battery replaced on limited range when the battery otherwise tests as "within average" of other vehicles my age? I have had the battery diagnosed at least twice in the last two months. Once while it was at the SC and the second time last week remotely. I have a Signature Model S P85 with the original battery. I am getting between 180-185 miles rated miles on a full charge. The car says it charges to about 214 miles but then the depletes more quickly. I am still driving an average of 300 wt/mi which has remained consistent over the life of the car. Over the last two or three months I have fully discharged and recharged the battery multiple times to try and recalibrate. Over that time, the only difference I have seen is a trending decrease from about 225 miles with a full charge 6 months ago.
