I wanted to report my second battery capacity loss:
Almost 2 full months from first bar (14 months total) - it will be 14 months tomorrow
Mileage: 23,652 (3,446 from first bar loss).
Habits between the first and second bar:
Trying to be as careful on the battery as I can, but because of range loss I am having to charge to 100% more often than just the weekends and have had multiple instances of QCing twice in a day.
I reported the problem to Nissan hotline under the same case (just updated the case) today to the same rep (Ricky). Interestingly, Nissan asked what my range was at 12 bars, 11 bars, and now 10 bars. In addition, they asked for information if I was still able to make trips I had before (such as to work, play, etc.) and my driving habits.
While I don't have hard core test runs and data (like ticktock) or oppossum/azdre on range, I do have some general data on my range. Usually I would push my car (not on purpose to one bar or LBW). Estimating the last few miles @ one bar is less room for error, so I figure my general estimates are in a good "ballpark." This is what I told Nissan:
12 bars (last summer) ~ mid 80's total range
11 bars (early 2012 summer) ~ mid 70's range
10 bars (end 2012 summer) ~ high 60's range
My trip yesterday, wind 5 mph (crosswind) and temps ~100 produced a range of ~ 60 miles to LBW, this jives with my numbers. I average 4 mi/kWh and do a decent amount of highway driving.
Odd note, its been a rather cool summer in Dallas-Fort Worth. We only have a handful of 100+ degree temps and maybe a couple over 105+ This is atypical. Today, when I got my bar loss, it was in the low 90's outside (I have never seen it this cool during August here).
