That was Scott's LEAF. His pending lease return was one of the reason's why Tony selected September 15 for the range test.
I don't have the data directly in front of me, but ya, all those 2011 cars were typically 3 or 4 digit VINs. I do know that Red500 was in fact VIN #500.

I just noticed that it's on the Wiki. Scott's car was a May 2011 delivery with a higher VIN. In hindsight, the capacity loss he experienced was nothing short of breathtaking: 4 bars in 14 months and 28,000 miles. He literally smoked the pack in about a year. Incredible!

My new battery came in, and my Leaf has been at the dealer for 3 days now, trending to the fourth. The battery was replaced early on, but something happened and the dealer is telling me that the new battery doesn't appear to have much more capacity than the old battery. I asked them if they reset the BMS (felt a little like a know-it-all), and they said they followed the procedure for the swap-out, and they have done a few of these battery swaps and not seen this behavior before. They have a call in to Nissan to help them out.

I can tell from the Leaf app that it was charged to 100% once on day 2, then it has been sitting idle ever since then. I am now hoping that they don't give the car back to me with this battery, as it has been sitting with a 100% full battery for several days in the 100+ degree outdoors!

The Nissan rep has called me and said that he is in touch with the dealer and will give me daily reports. I have a nice Nissan Altima as a loaner car.

Picked up the car today. The battery had to be replaced again because of a procedural problem installing the battery, but this one appears to be worth the wait!

Original Pack Before: Ahr = 46.6 (71.0%); Hlth = 50.34%
New Pack After: Ahr = 64.92 (98.96%); Hlth = 97.73%

So, technically speaking, this is now my third battery, since I had a battery replaced on Tuesday but and they replaced it again 3 days later on Friday. They think the second battery was good, but the BMS (or another computer, they were a little fuzzy with details) may not have been properly reset before installation. However, just to be sure, they overnighted a battery and gave me a third one, then they'll test the second battery to see what happened.

The battery hasn't been charged to 100% yet - not sure if that matters for the above readings.

I was glad it wasn't charged to 100%, since it was about 105 out, and I didn't want it sitting out there at full if I could help it.

It's amazing to have the range back to like-new! Thanks Nissan! SOC was only 73% when I picked it up, but that was 211 GIDs - 15 more GIDs than than I used to have on a full battery at the start of the week.

The Nissan EV support tech was calling me with status each day. I definitely was impressed with their level of support and he seemed like he was an advocate.

I also asked about the coupon/voucher for the 'Hot Battery', and the Nissan EV support tech did research this, and says that this will be sent to us in Spring 2014. He requested that I contact him on a regular basis (monthly or bi-weekly) for an update on this status. He says that another Leaf owner (I believe that's jhm614) also requested information about this when he had his battery replaced.

ImageGood to hear, thank you so much for sharing the experience. It would be great if you could catalog the health and capacity of the new battery. Even once a month would be plenty to spot any trends. This could be especially interesting if and when you qualify for the new more heat-resistant battery next year.

I believe the batteries are the same, its the latest software upgrade and me being a better hypermiler, that has help me increase M/KWH..

Some of Mark's comments are here:

Getting the 4BL confirmed

Possible Pack Cost & Timing of the upgrade

I think the pack price was incorrect but I can't find that post.

Longer recharge time on refreshed battery

3 Day turn on replacement

Possible Range Improvement on New Pack (but probably not)

I am wondering if any one who had their battery replaced under warranty got the voucher for a future "hot battery" replacement?

We were told in Phoenix that this was something that would happen sometime later - likely mid next year - when the release of the hot battery was more imminent... Remember that it is still undergoing testing and could, technically, be delayed or withdrawn if problems arise in the last 20% of testing...
