Actually, if you just look at the data versus miles driven I'm measuring 5.8% degradation per 10K at 15k miles driven and your experience suggests 3% degradation per 7.7 k miles but that was with the LBC included. My SOH went up 9% post LBC change. Did you notice if yours changed? .
Yes; my SOH was at 93.5% at 6.3k miles and 10 months (0.65% per month average). I didn't get a snapshot of it right after LBC, but I'm now at 97.04% at 9.1k miles and 14 months (0.21% per month avg.). (you have like 30 data points... I have like 3
On the "bright side," if you are degrading at 5.8% per year, you should get a free battery after 5.7 years. Then you could probably drive another 5.7 years (11 years, 4.8 months total) before you're back down to 8 bars. In my case, I won't hit 8 bars until 13 years and 1.6 months, so no free battery for me. We each would have spent about the same number of months at 12 bars, 11 bars, etc., except that you would have gone through two batteries to my one.
My guess is that we will both degrade faster as time goes-on, but unless 4 year compounded degradation is 30% more than 1st-year run-rate, we will both be faced with paying for a battery at about the same year. If it speeds-up by 30%, you might burn through the first battery before 4 years, and the second battery before 8 years; but I still won't hit 8 bars until 9.2 years.
