Out of curiosity, where does this 27.5 kWh come from? Tony Williams at http://www.mynissanleaf.com/viewtopic.php?p=101293 assumes 26.5 kWh usable. I don't know if he's right or what the actual/approximate usable should be on a 30 kWh pack.


I have 28.1 usable.

your statement tells us just about nothing.

did you reset your miles/kwh before the trip? what did it say?

how long did you idle (average mph is useless because of this)

how was the weather? wind? elevation change?

how did you cover those 64 miles? what was your maximum speed? average means nothing without total driving time or time on city streets

The top 4 numbers did vary a bit during a lull of activity including an ahr under 81.

it would seem readily apparent that this pack is much more reactionary to driving/charging habits than my 24 kwh pack was.


Interesting that you only show 363 GIDs with an 82 AH battery. My guess is that 363 is a hardwired max value and you won't show any loss in GIDs until the battery drops below 78-79 AH. With the cooler weather in Washington, your battery should last a bit longer than most. It might be that these batteries just age badly irregardless of the weather or the charge state. It looks like a lot of cars that were just sitting on the lot are showing similar losses so it could just be age of the battery rather than usage or temps. In any case it looks like Nissan screwed up and is going to be replacing a lot of batteries.

Seems they may have had a bad batch of 30kwh packs early on which has affected some of the first 2016 Leaf SV/SLs produced. At least that's what it looks like after reading this whole thread.

Ok it's the first of the year and I'm at 20,000 miles. Battery stat's have actually improved slightly to 70.04AH and SOH=88%. The cooler weather seems to agree with the battery. The loss in range is noticeable but not significant. I'm arriving home with 35-40% battery capacity instead of 45-50%. I expect that the battery might be stable until Apr-May when the weather warms up again.

what would be your estimate of GIDs then? assuming no restrictions?

I think the value for 82AH ought to be around 380 GIDs based on 82 AH X 360 VDC = 29520 wh / 77.5 w per GID = 380.9 GIDs. 78 AH would give 362 GIDs using the same formula. Either the AH value is off or the number of GIDs is off. The KWH value is calculated from the GIDs value and whatever you select as w/GID in Leafspy. If I'm right, you should not see any change in the GIDs value until the AHr value drops below 78.

I started out at about 79.5 AHr last December and didn't see any drop in the GIDs value until April. I really wasn't paying a lot of attention to the AHr values back then. Probably should go back and look at them again if I have recorded them from that far back.

I have 28.1 usable.

Based upon what? If it's what Leaf Spy says, I suspect that value that you're looking at is based upon the Wh/gids setting that defaults to 77.5. If you raise that, then for a given state of charge, the kWh indicator will go up. If you lower it, it'll go down. Try it.

We have no idea what that setting really should be and what caveats there are about its accuracy, what ranges/conditions it's not accurate or what ranges are where you should use a different Wh/gids constant.

ok. right now I don't know what LEAF Spy is set on but its been on same setting for years and I believe it is 77.5. so should I set it to 80?

Re: 2016 30 kWh Battery data

On Dec 30, 2016 I just bought (not leased) a 2017 SV with Premium Package Pearl White with black interior.

Recent Manufacture date of 11/16.
On an "old" version of Leaf Spy Lite:
AHr = 81.32 and HLTH =97.24

I hope to get the latest version of Leaf Spy Pro soon so I can read the battery serial number and get more accurate details

P.s. I got $7000 off MSRP + $3000 Nissan Rebate on an end of month, end of year deal.

P.s.s. I plan to sell my 2011 Leaf with 62000 miles and still fairly new battery received under warranty (went from AHr 66.14 to 62.23 recently). What do you think is a fair price?
1st bar lost at 23,500 miles/25 months
2nd bar at 34,000 miles/36 months
3rd bar at 44,300 miles/47 months
4th bar at 54,054 miles/57 months on3/17/2016 St. Patrick's Day
4/18/2016 at 55,066 new battery! AHr = 66.14
