2019 sr+ NCA battery degradation

[FrankAnz]

I have a 2019 sr+ with 65,000 miles. My range has dropped substantially since 60,000 miles. At 60k i had 214mi at 100% SOC. I has been trending down since then to now having 197mi at 100% SOC. I charge overnight, usually from anywhere between 20% & 80% up to 90%. Should I be concerned or just keep an eye on it. TIA.

This all sounds fine. Very normal. Worst case, that is just 18% capacity loss. (It may well recover some of that; could be as little as 16% probably.)

Sounds like you need to charge to 80-100%. But if you don’t, just use 50-60% when you can (60-70% or even a bit higher is probably fine in the cold months). Doesn’t really matter (it will help reduce future calendar aging) but just an option for you.

Charge every day.

In any case no reason for concern; this is very normal.

Thank you for your reply!

Just did a battery health check in the service menu and mine came up at 89%, so 11% degradation after 3 years and 39,000 miles. My 100% SOC range is 226 miles. OP's numbers look about right.
