Re: How long 'til 4th bar drops?

Sounds like a good find! How many miles does it have? Also, just make sure you are calculating the 5 year warranty from the car's in-service date. As long as you have sufficient mileage, 16 months should be a fairly safe bet to get to the 41-42 AHr range, IMHO.

You might also want to see if the seller will let you get an official battery report from a Nissan dealership, as if the battery was abused (for example, left discharged for a prolonged period of time), it could void the warranty.

Good luck!

@tungsten

My exact conclusion, based on all the readings from this thread.

There are 16K miles to warranty expiration.

According to Nissan Electric CS 1-877-NOGASEV there is NO BOE warranty annotation against it and therefore covered by basic warranty coverage.

Someone suggested I get it in writing from a local dealer which I did and they had no problem doing. They also included a full service history of the vehicle.

Is this normal for my SOH to not change? And to not see an AHr closer to 66?

...

Not normal based on my experience.

Capacity warranty new pack installed August 4th.

Showed SOH 100% immediately and still does.

Capacity showed 66.14 for long time but finally showed a tiny drop yesterday.

Hx held at over 100% for a long time too. But dropped down into high 99.9% range a few weeks back.

My guess is your technician messed up and failed to clear the long term capacity data when new pack was installed.

Once new pack was installed my technician spent about three hours on configuring software for the new pack.

The cell balancing is normal.
Mine did that a lot.
Not sure the new pack is yet balanced as well as the old worn out pack.

But that is understandable.
With the new range the new pack has only once seen LBW.
Old pack saw Turtle and pack disconnect a lot.
That helps with balancing.

@TimLee: Thanks for your reply. Makes sense that something in the software wasn't updated or reset. I'll see if I can contact the technician and ask them if this is something that needs to be corrected. At least I'm relieved to hear that the shunting is normal. Wish I was seeing AHrs in the 66 range, too, but at least mine seems to be stable at 64.38.

I'm not sure how significant the impact is other than inaccurate data from the BMS.

With time it will catch up. But may take months.

The reason and only appropriate use in Consult III of the Clear Long Term Capacity Data function is when a new pack is installed.

Many technicians have NOT understood that and done it when the pack was not replaced.

In your case I think the technician should do it.
Should take less than an hour and be no cost.
Should correct your LSP readings to those of the new pack.

Amazing thread on dropping that 4th bar, it is fantastic!

Been shopping around for a used leaf and lo and behold I've come across a dealer selling a used one with 9 bars.

Main starts are AHR: 45.05 / SOH 68%

Appears to have been driven in the high deserts of SoCal.

With 16 months remaining on the warranty and based on information contained on this thread do you all think this a pretty good candidate to drop the last bar and quality for a new batt?

Thanks!


Seems great. 45.05 AHR and at 68% SOH? Man, I'm stuck at 72% SOH with 45.40 AHR. Not sure why mine isn't dropping.

This info was taken from leaf spy. I've had 2 bars drop but from what I've read I should have had at least 3 bars drop right? I'm a little frustrated because 5 yrs in August is coming up fast.

It won't drop until your SOH is under 72% for probably at least 2 months. I've been at 73% SOH for a few months with an AHr of 48 and I still have 10 bars. I expect it to fall to 72% SOH in the next 3 months and to drop precipitously during the summer here in Arkansas. You'll be cutting it very close for an August expiration.

Thanks for the reply. Just to clarify 10th bar drops at 72%soh +2 months? Is the bar dropping related to soh exclusively? I can't seem to find a reliable source on how the stuff I listed relates to the bars. I live in Dallas btw.

Also... if summer is very hot and my soh says I should have lost 4 bars but the computer hasn't dropped it then I'm hosed right?
