QCs. How many are too many?

Mon Sep 21, 2020 11:44 pm

I looked at several used Leafs before purchasing this weekend. I considered:

1. 2017, 27k mi, 87 SOH
2. 2018, 7k mi, 94 SOH
3. 2018, 15k mi, 93 SOH
4. 2019, 10k mi, 94 SOH

Leafspy showed QCs in the single digits for all vehicles, except #3 showed 48 QCs!

As things unfolded, #3 had the best combo of color, features, price and was factory “certified”. I ended up purchasing it despite its many QCs because the SOH didn’t seem adversely affected at all. It was essentially the SAME SOH as the other 2nd Gens I considered.

I would imagine that Nissan has way too much invested in warranties and infrastructure to partner with EVgo (free QC charging) if QCs were horrible for your Leaf, right?

The consensus seems to be (high) temperatures, mileage and age are the biggest factors impacting battery life. Is the jury still out on quick charging?

What do you think? Is nearly 50 QCs too many? Should I avoid them like the plague now?

Go by the SOH (unless suspiciously near 100%) rather than the QC count. Two in a row on a hot day would possibly be worse than 50 single QCs on separate, cooler days.

I would lean towards the 2019 as it has the most remaining warranty.

Its so sad that things like this still need to be asked about a LEAF.

Any chance that 2019 is a leaf plus with the big battery?

Hi Jlv. Why is it sad? Can you expand on your comment? Thanks.

Darn I wish! No, didn't have a lot to spend and really wanted to purchase instead of lease. The 40kWh Leafs now coming of lease were hitting a sweet spot for my commuting needs and budget. Maybe the next one!

Your car should be fine. The SOH number is good so don't worry about the 48 QC's. One DCQC every few days is no issue. Multiple QC's close together will heat the battery and contribute to deterioration, but I never worried about an occasional DCQC. The 48 DCQC's on your car probably means the original driver used the Nissan NCTC (no charge to charge) program periodically like I did with my 2015.

This.

OP: Avoid QC when you can, use it when needed. DO NOT use QC because it is free or cheap (e.g. through the now discontinued Nissan promotion.) That is penny wise and pound foolish.
