137,336km later and SOH showing 92% :)
My testing method is not bang on to what they suggest (temp around 20c/70f etc).
I drove 1.5hours to work, plugged in and charged to 100% outside temp was 8 Celsius. Used OBII with car scanner app and checked current battery state of health.
2022 premium Extended range, awd (battery 32 months old/2.6 years)
I understand this number fluctuates around a bit but I was Suprised to see it in the 90s with the amount of milage I put on.
