Good morning sleepwalker. I love your avatar. I adjust my range as I drive depending on how far I want to go. If I drive at highway speed with aircon (12deg outside) I get around 80km. If I do the same trip at 80k/h (and I do it regularly) with range in mind, I can get it to 100km. (Interesting, 80/100 - 100/80 dichotomy:-) Thank you for noticing I though it was pretty funny. Your and caroline s data is a great set to compare with my stats. In particular the 100 km on full charge. What year is your car, if you don't mind me asking? > Regularly 14.0kWh to full. How many km was remaining when you plugged it in? Is this reported by the charger or LeafSpy?

LEAF's km on full charge is determined by kWh available in the battery, but more so on the previous driving history. Like (so I have read somewhere) 30km prior driving. If you return from a highway drive at 100kph and then charge it will calculate at 0.15kWh/km, your highway economy. If you charge after a week around town, it will calculate at 0.12kWh/km. Reciprocate the number and you get km per kWh. So 0.17kWh/km = 1 ÷ 0.17 X 14kWh = 82km.
My year of manufacture was 2012. I purchased in 2015.
The LEAF shows bars and kilometers remaining. LEAFSpy shows all the other stats including kWhs remaining. LEAFSpy is "adjustable" by the user to set kWh/Km,%SOC or kWh reserved and VLBW (very low battery warning). So LEAFSpy's range is different for each user and different to the LEAF guess-o-meter.

My SOH is now down to 64.67%. I am surprised that I have not lost my 4th bar but I understand that it has to be below 66.13% and stay below for one month.
I was definitely below on 27th May but prior to that date I was not recording decimal places so only had 66% recorded.
Looks like another week or so yet, then the long trip to Brisbane (from Sapphire) about 1300km.

More than 3 months after I lost my 4th bar, my battery warranty claim is finally approved today.
The dealer didn't say how long it will take to get the new battery but it is possibly another 5 months.
BTW, I ordered a Model 3 today. If Tesla delivers the car as estimated, I will be driving the Model 3 for 3 months before Nissan replace the LEAF battery.

My Hx has been below 66.13% for a month and I am sweating on losing my 4th bar any time now. Hx now down to 64.39% (dropping fast, I think).

My dealer does not have experience in battery warranty claims. I have to replace my VCU (which ships from Japan) before Nissan process my claim. Each step took a very long time. Before you drop off your car to the dealer, make sure your 12v battery is in good condition. My 12v battery caused error codes around TCU and confused the dealer and Nissan.

I have a 1000+ km trip to the dealer so looking forward to getting it done before the Hx drops too much further.

I had mine replaced because it kept going flat but it ended up being a faulty TCU - lucky I was still under the 3 year warranty- Nissan replaced it... haven’t had that problem since. Though I’ve noticed if I leave the OBD dongle plugged in the 12V charge sometimes drops a bit but nothing like before

I really hope that takes off and I really hope we'll have even longer range options in a few years.

Does anyone find their brake pedal acting weird from time to time? I find mine sometimes goes to the floor as if there has been a leak in the line and then sometimes the brakes 'bite' quite early in the brake travel.
I put it down to my ageing 12V battery as after i put the Ctek battery charger on overnight, the brakes return to normal but soon after starts acting up again. My understanding after reading other Leaf posts is that the brake booster runs off the 12v battery and if the voltage is not high enough will cause it to malfunction.
When i check the battery voltage using Leaf Spy, it reads 11.9V.
I have purchased a replacement Century battery and will pop it in soon.

Yes have definitely noticed this - will check 12V next time it happens.

I am also still on my original 12V battery. If you are having grabby brakes, ask to perform a brake reset when you have a service.

My LEAF was below 66.13% SOH on 27th of May. It is now 64.14% (and I feel dropping fast:-( ).
I am confronted with a 1300Km one way trip to the dealer in Moorooka Brisbane with lots of large distances between DCFCs. Current range at highway speed (90 - 100) is around 85km.

For those of you that have had your battery replaced under warranty over the last months/years, what have your SOH% readings been ? My battery was replaced 2.5 months ago by the previous owner. I only got LeafSpy set up about a month ago and it was 95% SOH back then but over the last few weeks it's dropped to 93%. At 100% charge the highest kw available I've seen (via leafspy) is 20.7kW or 267 GIDs. I'm particularly interested to hear the results from people that have had their battery replaced some time ago (eg Feng, lesmando24) to a get a feel for what to expect down the track with the replacement battery. Based on reading this thread it appears we still don't really know for sure what the makeup of these replacements really are (brand new, partially remanufactured etc). I also noticed that there appears to be two different replacement pack numbers mentioned in this thread. Mine was N295B-03NA6A (as was at least one other person's) and I think Feng's was N295B-03NA7A. I wonder why the difference ? A 7 sounds better than a 6 to me!

The new battery is the same chemistry as the original battery (lithium manganese oxide). Mine has done 55,000km on the new battery. It still displays 11 bars of capacity. But I suspect the second bar will go when I get about 60,000km, just like the original.

Is it wrong of me to expect more from Nissan?
In the 7 plus years the leaf has been in existence we are still having the same option in battery pack. Same heat sensitive chemistry, same capacity, price point isn't impressive at more than $500 per kW factoring the requirement of returning the old pack in for replacement eligibility. That could've been instated for solar storage.
Even if return was not calculated, at $400ish per kw still not really competitive.
Additionally, it's not easy to go with 3rd party cells as the BMS part of the pack can really only be reset by Nissan to relearn any new capacities.

But I suspect the second bar will go when I get about 60,000km, just like the original. The positive is the Leaf is definitely a reliable car even when it clocks up ridiculous number of kms. The huge disappointing bit is running cost per km alone is roughly the same with petrol car, compared with battery replacement cost (not including the car itself). I was expecting the replacement battery has better degradation profile. Sad. I'm hoping the aftermarket solutions will fill the gap, and soon. I need to replace mine by next year.

My SOH is now down to 63.98% and has been below 66.13% for at approximately two months now. Does anyone have some firm info on when I should expect the 4th bar to be lost?

Hi Jeff, Yours is indeed weird one, should've dropped ages ago. What's your Hx (with your SOH 64.14%)? Also, what is your kWh figure when you charge it to full? My SOH is at 69% with Hx 47%, and get 13.8kWh when it's fully charged now (in winter). If you get to similar figure (around 14kWh), maybe (my pure guess), there is something more behind the bar calculation...

My current Hx is 41.74% and SOH is 63.98% when fully charged several days ago. Capacity was 13.8kWh and temperature (at time of charge) was around 20degC.
I do know that worrying about it won't make it drop that 4th bar any quicker:-) but wish it would happen. I have a 1000km trip from here to Brisbane to the dealer for the warranty claim. Still lots of headroom in warranty time and 58,000 klms though.

Indeed. As if they have over the air updates to prevent this from happening...

Here's the latest readings and in the spreadsheet showing the decline. Super weird! Yours dropped 4% within 6 months!! Judging ours started the same in Dec 2018 (mine 70%), mine didn't drop just like that though. What's interesting, ours charged to the same figure, i.e. 13.8kWh. So... weird... Mine so far:
