You should probably get a battery check, although it may not be necessary despite the warranty language. It's unlikely the replacement battery will be refurbished, although we can't promise anything. Finally, the 40kwh battery is still a big question mark - all we know is it won't have thermal management, unfortunately. It is unlikely that Nissan will make it available as a replacement for earlier packs.

Not quite. 30 kwh pack would still have a bit more range.
I fit that category. My 2016 has a capacity of 18.9 KWh by LeafSpy. I could have bought a low mileage 2015 for 10-15K but bought a new SL and even after discounts and rebates it was 25k. In retrospect I would have been a lot better off with a 2015 S

https://www.facebook.com/groups/nissan. ... 990621501/ has a report of a someone just having lost their 3rd bar on a 30 kWh '16 SL at 18.8K miles in the Sacramento, CA area, which is a hot area.

Yet another report today of a '16 30 kWh 4 bar loser, in Florida at https://www.facebook.com/groups/nissan. ... 517192915/ at 22,668 miles.

Here is my first year report.

Bought my 2017 Leaf SV Just at the end of 2016 on 12/29
Using an old version of Leaf Spy Lite I recorded
AHr= 81.32 and Hlth = 97.24%

Now, after driving 9500 Miles on 12/29/2017 my readings are:
AHr= 72.68 and Hlth = 86.85%

So about a 10 1/2 percent loss. after 1 year and 9500 Miles.

Occasionally charge to 100% to balance out the cells, but drive it shortly after that.

Taking advantage of the NCTC Card, so
QC Cnt = 145 ( generally charge up to btwn 80-90%, often 85%)
L2 Cnt = 206 (Since I use a timer this number is about double actual charging events)

My garage is facing the West and gets a lot of Summer warming/hot sun in the 90s F.

At that rate you will have capacity close to your 2011 with a new battery. Maybe you should have kept it?

It's Jan 1 today and just over two years since I bought my 2016 Leaf. After 38000 miles I'm down to just over 67% SOH. Still showing 10 bars but I expect to lose the third one any day now. I still expect to replace the battery under warranty by June or July. I'm currently at 246 GIDs at full charge or about 19 KWH. I think I need to lose another 25-30 GIDs to qualify for a new battery. That could happen as early as April but I'm betting on June.

Doesn't that work out to < 60% remaining capacity ?
What happened to the "about 70%, 4 bar loss" warranty Nissan likes to talk about ?

The language in the US warranty booklets only refers to bars. It nowhere (that I've found in all the ones I've looked at) gives any sort of mapping of bars vs. % or any sort of warranty by % of remaining capacity.

Besides the table at http://www.electricvehiclewiki.com/Batt ... y_Behavior that was in the '11 service manual and removed in later ones w/no explanation (AFAIK), the only references I'm aware of re: 70% are at http://www.mynissanleaf.com/viewtopic.php?f=4&t=11043 and http://www.mynissanleaf.com/viewtopic.php?t=13192 (search for 70 percent). There might be others (e.g. videos) but I don't have a full list.

Does anyone know if the earlier table has reappeared in any Leaf service manuals or other official Nissan documentation (e.g. TSB)?

I can confirm it's on page MWI-23 of the '11 service manual but couldn't find such a table in the MWI chapter of the '12 nor '13 service manuals.

For the UK, https://www.nissan.co.uk/ownership/niss ... nties.html just talks about bars. Oddly http://corporate-sales.nissan.co.uk/GB/ ... ssFAQ.html, says
What happens if the battery life drops or the battery fails?

The battery comes with a 5 year, 60,000-mile warranty. It also comes with a State of Health Guarantee. This means that during this period, we’ll carry out whatever work is necessary, to make sure the battery life is at a minimum of 75% (9 out of 12 bars on the vehicle battery State of Health Meter). It also means that if any of the battery cells happen to fail, we’ll replace them. If you buy the vehicle and lease batteries, then the battery State of Health Guarantee runs for the length of your battery lease agreement.
Nissan's US warranty language is by bars, not by % of capacity remaining, AFAIK. We also have nothing that's been acknowledged by Nissan to represent % capacity remaining. All we have to go by is bars, unfortunately. Nissan can screw w/the mapping of bars vs. % capacity as they please.
