I had just taken the leaf on its first trip to disneyland and back.
Was it hot at Disneyland?

After a few days of rebalancing the pack, I got 1% back, but not the full 2%. I never left the car parked overnight below 20% ever again.
Do you have updated LEAF Spy stats? Your pack is not following the curve of others in your build time frame AND you live in a pretty warm area
Unfortunately no, that was my 2013 leaf S (built in Sept and bought in Oct 2013), which I turned in last year. That 2% drop happened in summer 2014. I had just taken the leaf on its first trip to disneyland and back. It was returned with ~79% battery health @ 45,000 miles, so it would've lost its fourth bar ~10,000 miles outside the warranty period.
My 2016 leaf S (current stats in the signature) is experiencing better degradation rate (~94% battery health @ 15,000 miles).

the 2016 is what I was referring to
As if your random halfway anecdotal thoughts are any better? Such as "80*" being a magic temperature where capacity loss due to "heat" occurs. In reality, it's all relative and the rate of capacity loss over time varies approximately with Arrhenius' equation - a 10C rise in temperature will double the rate of capacity loss. Storage at a low SOC is not the same as cycling the pack across a wide SOC range. Cycling a pack across a wider range of capacity will accelerate the rate of capacity loss.DaveinOlyWA said:sitting at low SOC will degrade the pack but people here won't believe you unless you can post a study (as if they were some sort of unassailable truth... :lol: )
In October 2015 I was around 47.5 AHr with 9 bars showing. I didn't drop to 8 bars for about 10 months, August 2016 with 43.3 AHr. Take that with a grain of salt since I have a 2011, but the 2013 appears to be pretty similar. So unfortunately, I think you're out of luck getting your car to drop that last capacity bar in 4 months.SeasonsAfter said:My nissan leaf is close to the warranty replacement date but I don't think I can get there with my leaf spy stats. Any suggestions? I have four months before the warranty expires.
AHr 47.47
I live in San Diego so it doesn't get too cold in the winter and run the hell out of it for the warranty but am afraid to kill the battery after the warranty period. I tried to call nissan's leaf line and they indicate you are **** out of luck if you don't get that 4th bar lost. No assistance on battery from my calls.
SeasonsAfter said:I know, with my numbers I don't think I will be able to get that last bar to drop in the four months time the warranty is still intact. San Diego has been hot recently so I am hoping to make use of the heat as best as possible. Too bad I couldn't get the battery pack with full sun the entire day...ha
My 9th bar loss happened awhile back but I didn't record this date. I think it happened last year so maybe I am in luck? ha
I took the leaf into the dealership over the weekend to get the battery check done. Wow, was that a waste of money. $67 to tell me my SOC is 71%...wow, I could have told you that...
Didn't get much from the Nissan folks other than 5 stars on battery. One Nissan guy (intake) said some customers can get 10% of a new battery at some point. When I pressed him on how this works, he didn't explain further. Basically he told me to drive it hard and hopefully the bar will drop.
Looking for anyone with any suggestions at this point. Being friendly with Nissan doesn't get you much. I figure they want that warranty to expire on you so they don't have to buy a new pack.
My current numbers from yesterday's full charge.
33k on ODO
1/13 manufacture date
in service date 2/21/2013
AHr- 46.94
SOH 71%
HX 65.09%
204 GIDs max
72.6% GIDs
SOC 97%
SeasonsAfter said:My 2013 doesn't have a quick charging outlet. I am only charging level 2 at my home so try to keep the car fully charged with it plugged in.
I try to fully charge the leaf and then take a long trip (A/C full blast, heater seats on High, steering wheel heat on) to turtle mode.
Mirrors on the ground of the car to get some extra sun pointing directly to the battery pack?
Still with these numbers, I think the only way I can get a replacement is if I take it to AZ or Palm Springs to bask in the sun as much as possible. Someone in AZ or Palm Springs that can help me out on my project? ha
No.keydiver said:If I recall properly (this is well documented on the site somewhere), the first bar drops at 85% SOH, 15% loss, and the other bars each drop with an additional 6.25% loss. So, you have to get below about 66% SOH before you lose the 9th bar and get a new battery.
