Is this normal?

after charging the car overnight to 100%, I check the following night and I'm at:
88.1% SOC,
185 GIDFs (65.8%),
14.3KWh
41/65Ah
390.5V, at 81 degree F.

This is a 2011, with 24k miles with 60 months set to expire in January 2017

and I only have lost 2 bars so far. I live in Texas and I have babied the battery from the beginning (80% charge), and now, I think I'll end with a lemon, as I'll miss the boat for the battery replacement.

Is it normal that charging to 100% only yield 90-91% SOC.

I'm about to give the car to my sister in Canada, as a winter ride (I know the pack is not thermally protected).
She just have a 25 miles commute, but wonder what the cold will do...

Any thought?

Hmm, from http://www.mynissanleaf.com/viewtopic.php?p=455984#p455984, you may not lose that 9th capacity bar in time. You can skim http://www.mynissanleaf.com/viewtopic.php?f=9&t=19967 for more stats as Nissan has never published the criteria nor anything about what Leaf Spy is able to read/query for.

Any chance you can send it somewhere hot for the rest of the time? Unfortunately, you're quickly running out of time for the Northern Hemisphere.

I'm afraid you are not going to make it. Not enough time left and not hot enough weather left this year. Too bad that you babied the battery. I understand why you did but now that we have hindsight... If you had been closer, several techniques could have been employed, but sadly I don't see that as viable for you.

It appears that 2011 - 2012 cars report their actual battery SOC and 2013+ report fake 100% SOC while the battery is actually charged to 4.13Vpc or 90% actual SOC. Can anyone confirm?

I know my '12 only charges to a max of 92% SOC while my '13 (SOH 90%) easily makes it to 100% SOC. I've never seen it stated they changed things in '13 but it makes sense that might be whats happening??? I kind of thought it was because the battery on my '12 is missing 2 bars and my '13 still has all capacity bars.

My 2011 has new battery installed on 08/2014 and currently is at 89% SOH, 84.5% Hx 57.3Ah and all 12 bars present. On 100% charge setting it charges to 90% reported SOC and tapers off at ~4.13Vpc. For these batteries, 100% SOC is somewhere between 4.2 - 4.3Vpc.
 
My 2012 SL generally shows 91% SOC after fully charging, so I would say this is normal.
