February 03, 2014 dsh Phoenix, AZ 28,870 miles 19 months 3/11 01069 4th Capacity Bar Lost. Will wait for 'Hot Battery' availability before replace.

I updated the feb total in the post above.
With 28,870 I would be tempted to get the cold pack now and assume I could make another battery by 60,000. Probably getting a hot battery then.

That assumes the 2013 chemistry degrades at the same rate as the 2011/2012s. Nissan has assured us that it is better and we do not have enough field data to verify one way or the other.

Any 2013s with a bar loss yet?

Wow that sucks!! 8179mi.? Is that some kind of record for mileage? It isn't even an Arizona car.

Nissan has not assured us the 2013 chemistry tweaks affected battery durability at all as far as I'm aware. Unless they told you guys on the advisory group something they didn't tell the public. IIRC, they said they were mainly made to help reduce the cost and not to expect any change in performance otherwise.

You're right, they told us the focus was on cost and weight reductions. Still, the possibility is there that the 2013 batteries are longer-lived than the 2011/2012s.

We should be getting some instrumented readings from 2013 owners by now, particularly in Pheonix. Unfortunately all we have early on from 2011/2012 owners are reports of bar losses, so comparisons are difficult. Still, it will be interesting to see how the 2013s are faring.

I can't find the post but LeafFan in Phoenix has a 13 and has lost his first bar.
