I am curious about the experience of MS owners who have put a lot of miles on their cars. Has the battery held up pretty well or has there been significant loss of range? Have you done anything special to keep the battery in shape, or do you simply charge to the max every day? I already own an S70 that I plan to keep a long, long time, so this is just me being curious.
Had an 85 for 3 years, now a 90D. Never thought we'd travel around so much, but the Tesla drive is so good, we all of a sudden had 80 some thousand on the Sig, and now near 30K on the D.
I never noticed much degradation. Was expecting maybe 5% in 3 years on the Sig, snd it was about that. I don't notice any on the D yet, although it charges maybe a couple miles lower than it did, Since it's expected, big deal.
As to charging, we are told that batteries in general don't like to be sucked empty or filled to the top. Some say it doesn't matter. But with 250 miles range at 90%, I don't seem to need to charge to full hardly ever. On heading out to Phoenix this weekend, I have two jumps of 230 miles with 80 mph speeds. So in that case, I charge to full at home or at the motel and skip a charger to save time, purely for convenience. I arrive with about 10 to 30 miles, and do short quick charges (15 - 20 min or so) for jumps to the next charger, usually 100 - 130 miles. There is one jump I take of over 230 miles, uphill 3000 feet, so potentially 260 miles. I make it quite nicely at 65 all the way.
With a 70, I would do it different. After having an 85, I knew I wanted more range, so the D option and the 90 kWh battery were very worth it.
