My 2011 sv Leaf just recently lost the forth bar ( See signature info)

I did not use Leaf Spy Lite until start of last July 2015 (about 9 months).

I usually drive almost 1000 miles a month.

When my Temperature Bars were 6 Bars I saw the fastest degradation (btwn .4 - .7 AHr)

When only 4 Temp Bars saw very little change in the AHR number.

When 5 Temp Bar AHr drop somewhere in between.
