Wow! That's a big drop for just four months. Phoenix heat strikes again.


Yeah, it wasn't full capacity when I got it. Wish I had had the LB App and I may have waited for another one. When I checked it with the App in April, it was 63 AH (rounded).

Just got the Elm & Leaf battery app running yesterday. First measurements show 55.23 AHr and CAP at 83.36% on our car. It has 32,745 miles on it, going on 27 months in service. Lost the first bar about 500 miles ago. Never DCQC'd, usually 80% but more frequently going to 100% charging to make the range work for longer trips. Mild climate use, battery temps never over 6 bars in summer, 5 bars in winter. App put temps of the battery at 75-78F this morning. In the heat of the day they were 76-80F yesterday. I'm starting to log my changes now, for sure. Not looking forward to losing the second bar.

Amazing how we can lose a percentage or so in capacity within the same month and a few hundred miles. If you look at the trend, you definitely see it diminishing.

Greg, how many miles are on your LEAF?

We just got a DCQC in Thousand Oaks (Ventura County)
Will be interesting to carefully track capacity before and after Quick Charging.
Its at the Rancho offramp (Transportation Center).

Perhaps someone knows the answer, but why do most of the Blink L2 stations cost $1.50-$2.00hr, and yet all the DCQC L3 stations I have seen are listed as no cost?
Not complaining, but it really doesn't make sense!

No offense, but what does posting this giant picture of a Blink charger have to do with recording "battery degradation data"? It makes it difficult to track results in this thread. :x

The Blink Plus L2 is $1/hr. and those other charges have been in force for a long time. However, the Blink QC fee of $5/charge is fairly recent so they may be having problems with the fee charge.
