I have been unable to get a consistent answer from service or sales on the BEST protocol for regularly charging my MS. Tesla has said we should set the "normal" charge for what we use on a regular basis. They did NOT say we should keep it at the "old" standard of 90%. I have been told that the NUMBER OF CYCLES is irrelevant, so charging, even a little, every day is fine. However, many of us (including me) have seen drops of 10-15% charge capacity with a year or 12k miles. I would really like to have an FAQ from TM engineers as to their current opinion on the way to maintain optimal condition/charge capacity. Has anyone seen such a post/comment? If TM is monitoring this forum, please advise. Love the car and want to maintain it.
