Let's pretend it is 1.2% degradation over the ~1.25 years you've had the battery. If everything was linear (it's not, but let's pretend some more), then that would imply about 20% loss of capacity in a bit less than 21 years, assuming you keep it that long and keep doing what you're doing.100% displayed is about 96% actual. (After 37,000 miles). I think that figure was just over 1% lower when the car was new. (Around 95.2% if I remember correctly....) That may indicate that my battery has degraded around 1.2% so far in 37,000 miles. Not sure though.....it actually is a much more complicated thing to determine.
If everything is linear, it would also suggest about 617,000 miles before losing about 20% of the battery capacity.
Obviously battery degradation isn't linear, but it can be approximated as linear over shorter periods of time and over fewer charge-discharge-cycles. Degradation does tend to get worse over time.
I'd say this makes me feel even better about the battery lifetime.
