There's little point in discussing the GOM: viewtopic.php?p=271853#p271853.

What was the net elevation gain/loss between the two points? You can use Google Earth for that (https://priuschat.com/threads/google-ea ... ts.100653/).

The amount it will have at full charge will depend on how efficiently it was driven for some unknown period of time before the car's charged. If you want high GOM values, drive down a long steep grade or tow charge the car then charge at the bottom of the hill. Want a low GOM value? Drive really fast and very aggressively w/the accelerator up a steep hill in the rain w/underinflated tires while having the heater blasting on full. Charge at the top of a hill.

Sendler, I reset the dashboard statistics before I left home.

5:30 pm drive from New Braunfels, TX to Town North Nissan Austin, I averaged 3.9 miles per kWh at a 51.8 avg mph. Given 27.5kWh estimated capacity of the advertised 30kWh battery that should be good for 107.25 miles.

From the 64.5 miles on the trip plus the 34 left on the GOM that is about 99 miles in capacity or 99/107.5 or 92%. The GOM was rising at the end of the trip due to slower traffic.

The battery level upon arrival at Town North was 30% or 70% used in 64.5 miles 64.5/.7 = 92 miles capacity

92 miles /3.9 miles per kWh = 23.62 kWh total battery capacity

23.62kWh out of a new 27.5(30)kWh battery = 85% of new battery capacity.

This aligns very well with Leaf Spy showing 69.43 Ah, 87% SOH and 315 GIDs out of 360

On a new 100% battery if I drove 64.5 miles divided by 3.9 miles per kWh I should have used 16.5 kWh and should have 11 kWh left or 40% on the dash and I am only seeing 30%.

Do you see any problems with my math?

So far the dealer has told it is within spec and that if I have an issue to take it up with Nissan. Nissan says if they sold you a car that is old and they represented it as new then it is the dealers problem.

Doesn't buying a new leaf that has been sitting around on a dealer lot, with the battery not having had the best of care (as is likely to occur on a dealer lot) actually work in your favor? Because the capacity warranty "clock" starts at retail delivery, it seems this will give you a better shot at getting a warranty replacement pack. A 30kwh pack has an eight year capacity warranty, getting a new pack in 7-8 years sounds like an ideal scenario, carrying you to the 16 year time frame where cars are pretty much done for anyway.

Yeah. It looks like Nissan was way optimistic with the new NMC battery chemistry in moving the capacity warranty out to 8 years/ 100,000 miles.

Reporting in after slightly more than a month and 2700 miles; stats are the same.

363 GIDs
28.1 kwh available
82.34 ahr
100% SOH
Hx from 94 to 102%

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.

I would be really happy with those numbers on my 30kWh battery. You can get 15 miles more than mine at 4mile per kW

GIDs = 316
Ah=69.35
SOH=87%
24.4kWh
hx=84.39

Hello,

Is the part number for the 2016 battery ; 4NP4A (with serial number) or is it 4NP1A (ev/hev) ? Or is this just a partial of the full part number?

From this wiki url, a 2015 battery replacement into a 2011 with parts shows: http://www.electricvehiclewiki.com/Batt ... tery_specs

These are the parts used when replacing a HV battery pack on a 2011-2012 LEAF with a 2015 "Lizard" battery pack.

1 748N2-3NF0A COVER BATTERY
1 748N3-3NF0A COVER BATTERY
1 295B0-3NF9E BATTERY ASMY
2 749D0-3NF1A BRKT ASMY-BAT M
4 01125-N0111 BOLT
1 24220-7S020 CLIP
1 297C1-3NF0A SWITCH-DISCONNE

So, comparing across, is the 2015 battery p/n 3NF9E the equiv to the 2016 battery p/n 4NP4A ??

Out of curiosity, where does this 27.5 kWh come from? Tony Williams at 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.

There is one little but important unknown still, which is when those bars start to drop wrt AHr/SOH.
