Re: 2013 Leaf SV losing battery capacity checked with LeafSpy lite

I'm dying to get to that 2013 SL with the Feb 2013 build date and LeafSpy it! Is it possible that a Feb build with 26k miles realistically showing 12 bars still?

Possible ? Sure
Likely ? I think not

LeafSpy will not clue you in to a reset. Only a decent range test drive* (say, of at least 30 miles) would let you sort out the real battery health.


*
Reset the trip meter for the test drive. This will also show you the consumption rate (in miles/kWh) for the test drive.
kWh = 1/consumption rate * distance traveled
Compare the SoC drop of the test drive to the kWh consumed. A battery in good shape drops less than 5% SoC per kWh

Wondering what the odds of this being the original battery pack? The Carfax and the Nissan service dealer do not show that a new 'Lizzard' pack installed... so is it possible that they reset the BSM?

Also, I sat in a 2015 SL this weekend that only had 12K miles but already had one bar lost and LS showed the SOH at 84%. That seems soon for that model year... wonder what the owner did to trash the battery that quickly. LS showed only 2 QC's and 498 L1/L2 charges.

Both vehicles were Chicago area vehicles.


If the 2013 were driven and charged with ideal conditions (some QCs and no top off charges), it is possible that the 12-bar display is legitimate.

The 2015 was likely driven short distances at low speeds and plugged in after every trip so that it spent a lot of time at full charge. With SOH at 84% it is likely that it recently lost the capacity bar. The AHr, SOH, and Hx numbers as displayed by Leaf Spy might improve with some deep discharges, quick charges, and highway driving. The Leaf Spy numbers always improve for a while after QCs on my 2015 and drop when driven slowly on surface streets with no highway driving for a few charge cycles. The numbers go back up when I resume my normal commute which includes freeway driving.

That seems counterintuitive to me as I thought EV's were better for more stop-and-go situations as opposed to highway driving? This also means if someone selling their Leaf does some fast charging before I connect LeafSpy it will make it hard to tell the true battery condition. Still a newbie so learning a lot with every new post read; Thanks much to all!

QC won't produce more than a few percent rise in SOH.

Well, no. More like up to 4% for each QC, usually less, depending on temperature and more. I've never seen more than about 12% total, but can't exclude more on a Leaf with less battery capacity than mine.

How many QC's on a Leaf have you done, Leftie?

The changes in SOH seen with QC use are not known to result in more driving range -- you know, the thing that actually matters.

None, as I have no QC port. I do, however, read about them here, and have for four years. If I write something inaccurate, please feel free to correct me.

EVs are great for stop and go driving and range drops at highway speeds, but the high current draw during highway driving followed by high current charging will improve Leaf Spy numbers (at least on 2015).

So I may have convinced the sales rep to bring the car to me (long story) is there anything I can have them do that will help me with testing the battery as explained above? He's got about a 20 mile trip to me and don't know if I will have time to do another 30 miles to check it out. Thx
