If you're looking for a newer car, you want the highest possible SOH (probably at least 90%). If you're hoping to win the free battery lottery, you want as close to 65% (or lower) as possible, with plenty of time and miles left for the 5yr/60k miles warranty.


2012 Rav4-EV | 2011 Leaf SL w/QC batt replaced 11/20/15 | Clipper Creek CS-60 | EVSEUpgraded 2013 Leaf EVSECompare EVSE equipment | 3.84kw PV


So after about four months with a replacement battery on your 2011 (now at about 30K miles), your new
replacement battery Ahr is at 57 Ahr, but SOC indicates 38%?

Hi Evoforce,
Unfortunately I don't have any previous stats. I only got the OBDII last week and have been monitoring the data for the past week or so. What I find disconcerting is the data on Screen 1 and the data on screen 3.

I have to charge once at home and once at work in order to be able to commute the 46 miles round trip. I lose about 7-8 pips each way.
On full charge for the past 7-8 days, here is what I see on Screen 3 when the car is fully charged:
------------------------------------------------------------
Date Gids Ah kWh
------------------------------------------------------------
3/13 AM 189 42.42 14.6
3/13 PM 189 42.37 14.6
3/14 AM 190 42.60 14.7
3/14 PM 188 42.28 14.6
3/15 AM 189 42.55 14.6
3/15 PM 188 42.40 14.6
3/16 AM 190 42.57 14.7
3/17 AM 189 42.35 14.6
3/17 PM 188 42.25 14.6
3/18 AM 189 42.42 14.6
3/18 PM 190 42.53 14.7
.
.
.

But in the first screen, I see this:
----------------------------------------------------------------
Date AHr SOH Hx
----------------------------------------------------------------
3/13 AM 44.654 68 61.42
3/13 PM 44.674 68 61.41
3/14 AM 44.674 68 61.38
3/14 PM 44.654 68 61.41
3/15 AM 44.654 68 61.41
3/15 PM 44.674 68 61.35
3/16 AM 44.844 68 61.63
3/17 AM 44.818 68 61.55
3/17 PM 44.765 68 61.52
3/18 AM 44.687 68 61.43
3/18 PM 44.746 68 61.59

The Hx number seems to be too high and the AHr numbers don't seem to correlate between Screen 1 and Screen 3.
Shouldn't the Hx number be in the 40's? Do the Ahr on Screen 1 and Ah on Screen 3 numbers correlate for you (and others)?
Thanks,
Bala.

Highly unlikely. The magic number apparently, is 43 AHr.

When did you purchase your car? If you have the time factor on your side, you might consider running the car down to turtle, and just leave it deep discharged for a few months. At some point in time, charge it back up and check the Ahr.

If you attempt to drive more miles to reduce the AHr, it ain't gonna happen for ya.

In my case, I have already given up hope. I won't make it to 43 AHr by July. :-(

I would definitely NOT deep discharge it for a few months. A. doing that for more than 14 days voids your warranty, B. you don't know how low the voltage can go before the LEAF doesn't even try to recharge it leaving it bricked, and C. who knows if Nissan has the ability to detect that you've done that and could actually void your warranty.

The only way you'll make it is if you stop driving it and cycle it without putting miles on it for quite a while. You'll need to drive it to get the capacity numbers to update so you would likely need to save up those miles.

I didn't know leaving a LEAF run down for 14 days voids the warranty. I was planning to pick up a used one at OLO this weekend, for all I know it has been left dead for lengthy periods. Would that show up on the battery health test the dealer runs?
