How long did they have your LEAF while changing the battery?

Very interesting. Would you mind sharing a few details?tokenride said:
Why? Cost? Totally new battery, or some modules?
What did you have to do to get it replaced?

This is his info:
Lost (1) Capacity bar in mid July '12
Lost (2) Capacity bar on Sept, 4 '12
Lost (3) Capacity bar on April '13
Lost (4) Capacity bar on July '13
I took it into get it ready for a warrnty claim. I was nervous becaseu I did not go in for the battery inpaction onmy first year of the lease. So I thought they would try to decline the warranty coverage for not meeting my obligation of taking it in for the battery inspection. They ran a diagnostic and told me I had 5 stars on all categories of how th epattery was treated. The Nissan tech, Kirk, from Empire Nissan called the Leaf dept and got approval to replace it at no cost. They made no waves about failing to take it in for the first year battery inspection.
The battery pack was ordered. I got a call from Leaf customer service every week to let me know there was no ETA yet. The battery pack took about 45 days to arrive. It was shipped from Japan because Tenesse is only set up to make the packs for the newer models. A+ service the whole way. Now I have anew pack fo the remaining two years of my lease.

I thought the packs were the same between the old and new models, they're not interchangeable? Does anyone know what the differences are? I hope Nissan won't leave the early adopters high and dry in a few years' time by saying the old packs are discontinued and leave the 1st gen owners without batteries.
The LEAF is a very rare car in Australia and there's very little in the way of other EVs and charging infrastructure here. On the plus side, I do get a kick out of being a bit different in traffic! Anyway, because of the rarity I hope I won't have twice the trouble of sourcing a replacement pack in ten years. I might even have to think of importing my own from a wrecked LEAF overseas!

^^^ Elsewhere in the forum, pictures show a slightly different shell on the battery modules, but the external dimensions of the sealed pack remain the same. Reportedly, the connectors on the pack are slightly different and would require a short adapter.

This is what we know:
1) The old/new battery pack MODULES are mechanically form/fit/function the same. Not only did Nissan go to a lot of trouble to make an EV platform (not a custom car), but it wouldn't make financial sense from a long-term volume perspective
2) Nissan has stated that most (e.g. warm weather) battery warranty replacements will get the "hot pack" when available in the US (sometime in 2014)
I think we can conclude that is Leaf got an "old" battery pack because that's all that was available; whether it came from Japan or US probably depended on parts availability (or lack there-of). Most of us hear about parts shortages here all the time--even though they are building cars (and battery packs) in the US.

power wise they are the same but electronics were removed from 2011 packs and moved to under hood on the 13's. that is why there is a gap in the hump in the "trunk" on the 13's

Should we merge these threads: http://www.mynissanleaf.com/viewtopic.php?f=30&t=14102" onclick="window.open(this.href);return false; so we have all the info in place?
My hypothesis is that while the modules should be interchangeable (so a single module replacement could be swapped around between any LEAF), enough of the pack case and internal electronics changed that the pack as a whole is not swappable. At the very least, the '13 LEAFs have a different color case than the '11-12 LEAFs.Stanton said:
Nissan doesn't have spare '11-12 packs sitting around here in the USA, so they ship them from Japan via boat (which explains the 45 day delay in getting the pack). Nissan doesn't want to swap out 48 modules - too labor intensive compared to swapping out a whole pack.
I do wonder how they will start handling "hot pack" replacements. Perhaps Nissan will manufacture the "hot pack" world-wide, but it still seems to make sense to use as much domestic production as possible.

we are all chill on the battery replacement-sale price thing, and it is OK to be giving nissan some time.
i hope it yields more than the last time we gave them some time: what we got instead of a promised-price for a new battery; it was the SYB.
nissan can do better than that for its betas.

Umm .. What are you saying, Dave? The charger was moved from the trunk to the hood, but that is not electronics that ever was or ever would be inside the individual modules. It has no effect on either the size or the electrical connections to them.DaveinOlyWA said:

pretty sure (which means not positive) that there were other things moved around due to this configuration change. now does that make the modules inside non interchangeable? dk. guessing they are not interchangeable because the entire pack is being replaced which means using a 2013 pack will leave him missing parts.
best way to go about it? dk that either but guessing its a huge reduction in labor costs. unplug, unbolt old pack. reverse process with new pack, done.

I think it would be best to speak in singular, as I'm under the impression that there are several owners here in this forum, which might not agree with this statement. Also, and perhaps it's just be, but I'm not a big fan of this type of loosey-goosey approach.

my apologies for having some word fun.
I sorta thought that "SYB" (as a title) would speak volumes.
put another way, i wouldnt confuse that with approval.
yes, do steal my battery.
and thank you very much. i would be glad to endorse your product.
to be clear, they have some rope, let's hope they dont hang themselves and the 2011-12 beta owners with it.

From what I was told by the Leaf specialist, the Tenessee plant is set up to only make the newer packs. From my understanding the '13 Leaf packs were redesigned to make more room int he trunk and make it more practical.
As far as the swap out goes, the Nissan dealer tech, said that went he went to "Leaf School" they mainly trained him on swaping out entire packs and not modules.

I spoke with the LEAF tech who works on my car and he mentioned that disassembling and reassembling the older battery packs is considerably more difficult and time consuming than the 2013 packs. He gave me his training manual to read while I waited for my car. It showed how to break apart and reassemble an older battery pack using straps to hold the stacks of modules together until they could be fitted in place. He told me that the new (2013) modules were designed to fit together better and be easier to break apart and reassemble.tokenride said:
As to what it would take to fit a new pack in an old LEAF, I would guess that some plugs and electronics are different. My guess, and that's all it is, is that when/if the "hot" battery pack comes out, it will be made in two versions: one that will fit in 2011/2012 LEAFs and one that will go into the 2013/2014 LEAFs.

It's been my experience that Nissan doesn't want dealers cracking ANYTHING open.
The dealers don't even have access to the part numbers for the "innards" of this car.
It's all "swap the big boxes" out at this point.
They are for sure not going to have any dealer around here cracking open a traction pack assembly.
Not by a long shot.
it's: Big box shows up; big box goes back.
My guess is, from what I have seen, that once you have swapped out your third battery assembly and have it down, you could probably do the whole deal in an hour.
(I've seen it done once to run some "new wires"
under it on a '12, and it only took us an hour once we got the correct lift set up)

they arent swapping out individual modules. too much work to balance and match them. they are swapping the entire thing.
right now we all assume this is due to bad batteries but what if its not? could be borderline batteries with a bad controller, connections, out of spec materials, etc.
swapping the entire thing allows Nissan to look at everything. after all, could be something else or something that is helping the batteries go bad. now its easy to blame the heat especially when the bad packs are popping up in AZ but what about Drees? moderate San
Diego climate combined with boy scout charging habits. he shouldnt be there but he is...
if u just swap the modules, all you have is the results which may or may not include the cause
