Re: Capacity Loss on 2011-2012 LEAFs

I'm thinking I may need to do Uber on the weekends this summer to get enough miles to get my warranty in. I have until October. I may force the wife to drive my car whenever her destination is in range as well. lol.

10 bars
48.12ah, 73% SOH, 52.59HX
28,600 miles.

I've owned the car 5 months, and I've only lost 0.5ah in that time. I'm hoping the summer temperatures in the 80s and 90s along with freeway driving will help me along, but with no QC access, and in the interest of playing fair, I don't intend on using any "advanced techniques." However trying to put as many miles on it as possible is an option. I average about 12-14k miles a year, typically. I've put just under 5,000 miles on the car.

Don't "shoot the messenger", but there's just no way you're going to get to 8 bars by October...even if you lived in Arizona.

I had my 2012 for about 9 months in Texas (hot) when it dropped from 9 bars to 8 - I got a new replacement battery in Nov. of last year. Bought it in Late Jan 2016 with 25520 miles (Did not have LeafSpy at the time). The 8 bar drop happened at 29,720 miles in October at 42.6 AHrs. If you "assume" (you and I know what that means) that the new battery was typical 66.14 Ahrs, the four bar drop happened at about 5.9 AHr/bar rate for me. IF yours is similar, that would mean your battery is near dropping to the 9 bar level ~ 48.5 AHr. Caveat!! - I'm not so sure the "drop" is the same for each bar, so this could be off somewhat. There is a ton of information on this subject on this site - just don't remember the specifics.

So - based on my experience it certainly is possible since you drive more miles - and have the opportunity to expose the battery to more "difficult" conditions. I did a few QC's - probably 3 total. Mainly, I drove it on the freeway at high speeds, took it to shut-down several times and kept it charged to the max at all times (must have home level II charge system!). All this during the heat of the summer - which lasts 8 months here!

Good luck!

Correction may be in order for my last post - appears there is reported a larger "drop" (15% or almost 10 AHrs?) for the first bar. That would result in a smaller AHr delta required for the remaining bars dropped.

More like 3-7 ahr. I lost my 4th bar at 41.5.

capacity bars 15% for 12th, 6¼% for the other 11 then you have a reserve.

On my 2011, it seemed that it would be about 7500 miles and the next bar would drop. At some point I'll find the exact data and post it, but I eventually lost down to five remaining capacity bars at just under 60K miles. And it still seemed fairly linear for me, and worked out fairly close for 15K for the first bar, then 7500 miles per bar for the other six. It also seemed to be about 1 ah / month decrease, and I too drove about 1000 to 1200 miles / month. This was in Florida. I rarely saw less than six temperature bars, but I can't remember more than once ever seeing seven temperature bars, and never anything more than seven. It was occasionally down at five temperature bars.

I wouldn't worry about QC or anything else except the heat and the mileage. You will find too that you have to charge the car more and more often, keeping it at 100% charge, as the range diminishes, so that is supposed to also hasten the degradation. I don't know that freeway driving will matter either, as in my case I ended up driving slower than old ladies and it was still dropping at about the same rate.

So 15K miles in 6 months is really driving it, but definitely within the possibility. Especially if, as others have said, the 10th bar is about to drop. And then, it would be closer to 7K to 8K miles in 6 months.

15% for the first, 6.25% for the rest...

peakay wrote:Sorry if I am not as knowledgeable as some others on here, but I wanted to get your take. We have a 2012 Leaf SL and its in service date was Jan. 3, 2013. I'm trying to estimate how likely it is we'd qualify for a replacement battery before the warranty expires on Jan 3, 2018?

Here are our stats now on leafspy lite: AHr: 47.80, SOH 72%, 384.0V 29,733 miles, 4QCs, 2391 L1/L2s

Its at 10 bars now, been almost a year since we lost the 2nd -- how likely do you think i is we'll see 8 bars by 1/8/18? We put about 10k mile sa year on the car the last 2 years.


Opinion needed on how likely battery replacement will be. My above message was from October of 2016 and here are our stats now (with 9 bars):

AHr: 47.13, SOH 71%, 391.97V 29,733 miles, 4QCs, 2579 L1/L2s

We have until the end of the year -- how likely would it be to achieve needing a new battery if this is a 2nd car putting maybe 5k on it? if we keep it, would plan to quick charge it to help get it there. We have until December of this year. Likely or a stretch?

Thanks!
