What is your battery state of health?

Jan 2022 with 42k miles - SOH is sat around 94-96% depending on weather and recent charges. In the last 3 months it has read 96/95/96/94/96

Charged most days to around 75% then driven to around 40% - once weekly/fortnightly fully charged and then driven for 2 days to around 20%.

The Mini has a larger than usual 11% buffer in the battery - only 88% useable at new. The Pug e208 has 7%, Hyundai are typically around the 4-5% buffer.

They all have 7/8 year warranties but that covers if capacity drops to below 70%, by my estimates at my current use the car will be 9 years old before i'm down to the original useable capacity.
