I suspect your usage pattern is no more stressful or even less stressful for the battery than mine, but the LBC has trouble measuring or estimating the actual battery capacity under those gentle use and shallow discharge conditions. If you are concerned about numbers, you could run it down to VLBW and charge to 100% once a month. An occasional QC from VLBW to full charge if you have any stations nearby would also help your numbers. Since my Leaf Spy numbers improve after every QC, I try to use a QC from VLBW to full at least once every couple of months now that I no longer have 30 minutes of free QC.
One theory I have is that the higher sustained reverse current flow from either high-rate (6kW) L2 charging or especially DCQC breaks down the buildup on the electrodes in each cell. I have attached a link to an article about battery deterioration that you might find interesting.http://batteryuniversity.com/learn/arti ... ion_to_die
Thanks for chiming in. I'm going to follow my own advice to others and stop worrying about a number I cannot reliably interpret. I'll just keep trending LEAFspy once a month and hope to see the line plateau. As it is, I have no problem driving 100 miles on a full charge so I have nothing practical to complain about.
