Battery Degradation as a function of age OR mileage

DaveM 2 weeks ago 0

The "Battery Degradation Report" is very interesting but I have a low mileage M3 (~12k miles) that is 28 months old.  My degradation report is showing a more extreme capacity decline since I'm being compared to much newer vehicles.  It would be interesting to also be able to see how my car compares to models of the same age.  Comparing vehicles with similar age AND mileage would be ideal but I suspect that population would be very small.
