Bay Area Leaf
Lost first bar Oct 9, 2013
Mileage 28,600
Received vehicle May 12, 2011

It doesn't appear that I will have 80% capacity at 5 years and 70% capacity at 10 years even in the relatively mild Bay Area climate.

Anyone have a guess if I'm on track to qualify for the battery replacement before 60,000 miles?

Lost second bar Dec 31, 2014 at 42,740 miles
Lost third bar April 11, 2016 at 57,600 miles

Won't qualify for free battery after 5 years (May 11, 2016)

Can you update your location info via User Control Panel (near top) > Profile (left side)? That way, we don't need to ask in future posts/threads or do sleuthing to deduce it.

As for "relatively mild Bay Area climate", it really depends on where. Folks who live in places like SF, Half Moon Bay, Pacifica, etc. have very mild climates. Those who live in say Walnut Creek and Concord have it much hotter in the summer.

ChipsLeaf is in East Bay. San Ramon and Hayward were mentioned in an earlier post.

The best calculation I have found for if you will hit the battery replacement is in Tuning the battery aging model.

You will need to get an Ahr reading on your battery pack with the Leaf Spy app. The App is well worth the 15 bucks for the pro version.
Lots of good information on your battery pack.

Garaged in San Ramon during night. Parked in mostly shade in Hayward near the Bay during the day.

I think you are going to just miss the warranty. :(
I received my LEAF same month and I believe I have maybe 50/50 chance.
Best of luck.
1 bar lost at 21,451 miles, 16 months.
2 bar lost at 35,339 miles, 25 months.
LEAF traded at 45,400 miles for a RAV4-EV
RAV4 traded in for I-Pace Dec 2018

In the summer, I'm guessing San Ramon garaged at night is probably about the same temp as the Hayward daytime max. I sometimes ride between the two, and there's typically at least a 10 degree difference in the max temps, often 15 degrees. Especially if you're down near the Bay/airport. Being east of the hills is often worse temp-wise than being in the south bay.

I think you're going to be close.

Cool! Did it have 12 capacity bars? Get any gid readings on a 100% charge? If you don't have the equipment, I'd imagine someone in your area can help you out.

I drove my 2011 12,750 miles before exchanging it for a 2013. During that time I went below LBW 68 times, and 14 of those times I went below VLBW. Only once did I go to Turtle, and that was just as an experiment, driving around the block near home for the last couple of miles. Unlike Tim's guess, I never had any external device. I did keep close track of trip mileage at LBW and VLBW, and used Tony's rule of thumb that the distance from VLBW to Turtle was half the distance from LBW to VLBW.

My total mileage was low, and my climate not too bad, though we do have a number of days over 100°F each summer. The car always sat outside and nearly always charged at night -- usually to 80%. Even on the hottest days the nights cool to below 90°.

I didn't have data to allow any sort of accurate battery capacity calculation, but rough estimates based on miles, m/kWh, and charge bars suggest that I might have lost 2% to 5% capacity, but probably not much more than that, in the nearly 13K I drove the car. This leaves me with the impression that using DOD below 80% is not significantly harmful. I do have a different impression about going below VLBW (~90% DOD), though. I remember seeing a graph (perhaps from TickTock?) that showed a sharp knee in the voltage drop at about VLBW. I'm no battery expert, and you'll have to excuse the anthropomorphism, but that looked to me like a scream of pain from the battery.
