Just lost my first capacity bar this morning. My 2011 LEAF has 35,365 miles, delivered 8/25/11, located in South San Jose (Almaden). The beginning of the heat wave yesterday in San Jose may have been the tipping point.
Had mostly charged to 80% once per day (weekdays) for the past 22 months, but started charging to 100% during the past 2 weeks. On weekdays, the car has sat in a shade in a car-park in Sunnyvale, CA. Varied between 80%/100% on the weekends, and only FC when the ambient temp is below 70F. Avoided FC in summer, and only FC once per month in the other 3 seasons for the past 22 months.
Car is mostly at 5 temp bars for the 1st 3 seasons, but edges to 6 bars in the late spring and summer. Only saw 7 bars once, and only when I FC at 74 degrees (would never do that again).
Garaged the car overnight for 3 seasons, but starting this summer, started parking the car outside, overnight, and used the portable trickle charger versus Blink to keep the battery cool, or cool it off. Kept the ICE outside of the garage overnight as well, as that car really heats up the garage (probably cooking the LEAF battery). In hindsight, I probably should have done this last summer--but who knew until last year that the battery would degrade quickly from heat?
Been reading MNL for the past 2 years, and had been paranoid about keeping the battery cool since the news of battery degradation came out a year ago. Haven't posted previously, but now I got to, given the first lost capacity bar.
Ironically, I lost the bar today, right before my appointment with the Nissan Dealer (for the 2 year annual battery report and P3227 software update). Curious to see what happens after the appointment.
Car has been great otherwise, and we never expected to use it as our primary car--but it definitely is used as our primary car. We've gone just about everywhere in the the SF Bay Area in our LEAF.
Can someone add me to the Wiki page? I'm curious to know how many other folks in the SF Bay Area have lost a capacity bar.
