Hi Leafers,
I purchased my Leaf in Nov. of 2015. It was off lease from a cool climate (Chicago) and only had 14K miles on it. I was very pleased with the early readings I was getting from LeafSpy. Here's a sampling from Jan (Date/AHr/SOH/Hx):
So you can see in the cold weather I was getting almost unbelievable readings for a 2.5 year old battery.
Feb/March, I started to see a decline from the 98-100% SOH. Nothing drastic, but noticeable:
Now May/June and the decline is starting to really bother me.
On the one hand, I know that keeping a 3-year-old battery in the upper 90s for SOH is unrealistic (I think), but I'm worried maybe something I'm doing is causing the decline.
I do live in NC, and it is a warm spring. We have already seen temps in the 90s here. For a while I was charging at work during the day. Lately I have been reserving charging for overnight in my garage. It is parked in the sun for most of the day though.
I drive in B-Eco. I charge to 80% most nights (though now that my kids are out of school and I'm really just driving back and forth to work I'm only charging every 2 or 3 days, but that is very recently new and not factored at all into these numbers).
Should I expect the rate of loss in my total AHr's to continue to decline? Will it climb back up in cooler weather? What could explain this rapid decline? Is this even a rapid decline? I'm still not sure how my battery was reading what it did back in January.
At first I would charge up to 100% and see 101miles on the dash. Even though that was unrealistic, it is a little surprising now to charge up to 100% and only see 83 or so.
