I purchased my Leaf December 18, 2011. At that time I did not have a LeafCAN but I assume the battery was 281 gids.
On June 2 my Leaf read 281 gids and 100%
Yesterday morning my display for 80% read 221 gids or 78.6%. In June it read 82.4%
This morning my 100% charge read 264 gids or 94%
My conclusion is that the battery was affected by this summer's Anaheim temperature. At this rate the battery will still be above 80% when I turn in my 3 year lease. I am not happy with any degradation but that is a fact of lithium life. Motorola expects 3 to 5 percent a year and Cadex, the manufacturer of battery analyzers, says never purchase an old battery.
One of the members of a group I am in fly's electric model airplanes. He keeps his batteries in a refrigerator for storage and transports them in a cooler. We can not do that. Unless you live in Alaska the battery is going to warm up and we have to live with it.
On the Tesla forum one of the members was deciding on batteries. Since they have stated to expect 70% in seven years he was going to go for the larger pack. In my case after 3 years the battery is Nissan's problem. I am glad I leased.
