Decided to do a 100% charge today and got it to 230miles at 97% charge. I am not aware of the what the initial rated mileage was to compare for battery degradation. Can anyone comment? Thanks!

2015 70kw Battery Full Charge Update
- Thread starter incrediwoah
- Start date
Good to know! then I assume my battery has degraded only a small amount
Can anyone else confirm?

Technically, you're right, but the battery capacity should directly convert to rated miles. If you really have 68kwh, then you haven't seen much degradation at all, given that usable capacity for a new 70 was about 68.8 kwh. I would guess you're 100% is about 237 miles, which is only about 1% degradation from the EPA rated 240 for the 70d. You are doing much better than I am. My 70d is at about 64.5 kwh, and about 225 miles at 100%.

the original Model S 70 (RWD) introduced in 2015 has an EPA rated range of 230 miles.
the AWD version Model S 70D from the same year has a rated range of 240 miles
(my 2yr old 23,000km 70D at 100% charge still shows 384~386km, i.e 238~240mi)
btw this is a different battery than the 75 introduced later (a couple people above mentioned the 75), and so not directly comparable
Ah interesting. Anyway to see this on the screen?
haha awesome!
Thanks for sharing!
Can you and the OP please get the units right?
Battery capacity is measured in kWh, NOT "kw".
When you start mixing things up and talk about charge rate, which IS in kW, then it becomes really confusing and you're confusing yourself.

2015 70D (the real 70kwh battery), EPA rated for 240 miles.
When I just got the car, my 100% was 244 miles I think.
After a few weeks/months, my 100% was around 240miles (where it should be)
2.5 years, and 51k miles later my 100% is around 232 miles. So about about a 3.5% degradation from the EPA rating in 2.5 years and 51k miles, I think it's good.

Man, I wish I had one of these 70 packs. My “75” has lost over 8% capacity in one year and 36k miles. Super disappointing.

I’m 1.5 years in and I’m down about 5%. Have you run your pack down and up to 100% a few times? I found that optimisation kicks in and you end up with some higher values after a few cycles.
So yesterday I went to the EV meet, saw Sparky's new M3 he just picked up from Fremont and took it down to 20% and then back up to 90% and then back to 20% and now today back up. Car is still reporting 67.8 usable which is great but I take care of my packs!

Maybe that's why mine is showing so much (well besides being a real 70, without the silicone anodes). We drive a lot, and I don't baby the car. So I charge to 100% before every trip, and I get it to down to the single percent digits on most of my road trips.

How many miles?
I've been on both ends of the charge spectrum multiple times, charged to 100% probably 10 times and been in low single digits about as many times. Nothing has made an appreciable difference, I've never "recovered" any rated range. The trend goes only one way, down. I keep hoping it's going to stop soon but here I am with a rated 100% of 229 miles at 37k miles and no sign of slowing down yet.
I have a 2015 70D. At 100% It is usually 228 - 232 miles, vary on the weather. I am at 48.5k miles at the moment. I don't remember exactly, but vaguely recall seeing 236 at one point or another during the first few months of purchase. Since then, it varies 228 - 232.
