Hm, this thread was mainly focused on the questions, surrounding when/why is Nissan still delaying disclousure of key features (warranty, life cycle, temp issue recommendations) of their proprietary batt. pack technology in the light of more info-forthcomming competitors. Pls. don't derail it into techno thread only, there are other active posts for that in this very forum.
I'll only add here that it's indeed great there are varied approaches to it (Tesla, GM-Voltec, Nissan-Renault), they pursue different goals, power envelopes and market segments.

Where in the world are you from, Mesuge? Can you buy a Leaf or should you be beating on someone on a 'my Renault' forum?

Jess has clearly stated that she's told us what she can and will tell more when she knows it.
Nissan has published plenty of tech data, as has the battery manufacturer (AESC).
There are other web sites that give plenty of detail on what a LiMn cells is, how it acts, how it's charged, lifespan, and other details. That's engineering stuff - not 'joe consumer' stuff - and it's not likely we'll be able to get that level of information from ANY Nissan rep hired to work with the public - even after the car's been on the road for years.

I've been involved with engine oil specifications and testing. A dealer rep or customer service person WILL tell a customer which product to use (or which standard to look for), and when they recommend changing the oil - but will not and/or can not tell them what's in the oil, how it's made, or give away any other info that would help a competitor use the results of their time, technology, and/or experience for free.

The next info release is scheduled for June - you're likely to have to wait for news just like the rest of us. :)

I would like to know who the
more info-forthcoming competitors
are.

I don't know the
disclosure of key features (warranty, life cycle, temp issue recommendations)
of the iMiEV, the FocusEV (heck I don't know the price of the Focus EV), the Fiat 500EV....or any EV coming to market any time soon.

We won't see the LEAF til Dec 2010, and only in a few markets...and only about 5 to 10k cars at most at first.

Nissan has stated they will have more info out by end of June. We will have plenty of time to cancel if we don't like what we hear about these "key features." And they are important. Of course if we don't like the LEAF's features, well we are kinda out of luck for a while. Nobody else has an EV ready to go that is highway capable and multi-passenger.

But that should change over the next couple of years...YEAH. Choices are good. Nissan putting the pedal to the metal / stepping on the Electrons so to speak, is a good thing...heck a fantastic thing that has made all the other manufactures take their heads out and also speed things up.

Thanks Nissan...even if I prefer the Fiat 500EV, I appreciate all you are doing and will gladly support you by "very likely*" buying a LEAF this year or early next.

Gavin

*the only way I don't get a LEAF is if suddenly either Fiat gets the 500 here early next year (doubtful) or Ford gets some info out STAT on the FocusEV and I like the specs and other info better, and Ford also moves up the release date to similar to the LEAF (also doubtful as I don't think Ford has the ramp up ability at this time to match the LEAF...until Ford grabs back the FocusEV from being made out of house and gets it back in house, well it can't get 50k FocusEv done in that first year.)

Trying to identify the "limiting" sheet and brick can be relatively easy if the pack is sufficiently instrumented, but finding the "weak" cell inside the brick usually requires separating the parallel cells and running more tests. Generally, a lot of work, even after one is able to detect that something is "wrong" with the pack.

GM Volt holds a press conference every other day - and yet we know almost nothing about their battery pack. So who are these mythical competitors with lots of info. May be you are talking about cell manufacturers like A123 - not auto companies ?

BTW, the answet to your question is right in the question - you won't get any of that info because it is a proprietary batt. pack.
1st Leaf : 2/28/2011 to 5/6/2013
2nd Leaf : 5/4/2013 to 3/21/2017
Volt : 3/25/2017 to 5/25/2018
Model 3 : 5/10/2018 to ?

From the thread starter it seemed the thread was asking when we would know more information...a nice question. a simple question. a GOOD question.


I saw nothing from the thread starter as to
why is Nissan still delaying disclosure
.

So we can accurately state for the thread starter, "Nissan tells us they will have more info by the end of June, possibly earlier."

Now we can hope for early. Heck we can ask Jessica to see what info she can give now. But I'm not sure how it jumped suddenly to Nissan purposely "delaying disclosure." But perhaps we have a language barrier. Perhaps that just means "Nissan--like Ford and Mits and Fiat and every EV maker coming out soon, hasn't let everyone know just yet, but will soon like they have promised." And not some ominous plot like it sounds in my head when I read that.

Is it fair to let the public know the battery warranty spec before they make the pre-order?

Why ? Everyone knows it is yet to be disclosed ...

I would want a lot more details (lease, etc.) before I decide to lease or buy (or not).

And, the $99 is relatively "small", and fully refundable.

From Chelsea Sexton's chat with GM-Volt.com yesterday:
2:08 [Comment From Earl ] Chelsea, do you have any idea what kind of battery life is expected on the Volt?
2:09 chelsea: I haven't seen announced estimates from GM, but the state of CA requires a 10-yr /150k warranty so I'm expecting that's the target.
