Irvine is a transition from inland to semi coastal. NE Irvine can be somewhat warmer than SW Irvine in the summer.
Yes fairly similar to SA & Orange. Anaheim is probably a fraction warmer.
SNA (John Wayne) airport is a bit more coastal. More like Costa Mesa than Santa Ana.

Took 3 bars for the first time to get 10.5 miles to work today. :|
1 bar lost at 21,451 miles, 16 months.

Not liking this OC 3 bar loser discussion at all.. I'm on the warmer side of Irvine (near the 5.. probably not far off downtown Santa Ana temps vs John Wayne/SNA or UC Irvine area..)
I have been taking semi extreme measures to keep the battery cool and spend little time at higher SOCs although I'm already under 59Ah with about 1 year of driving and 16k miles. (It was 66Ah, 280 Gids a year ago). In the winter the battery is usually 18-25C (5 bars) and the summer usually 25-35C (6 bars).
Not long ago I would have thought those new "high temperature" batteries would have only been needed in places like Phoenix, Palm Springs etc... not (near) coastal SoCal (!!)

First capacity bar finally bit the dust at 24,975 miles, 31 months, capacity 54.69 Ah. I estimate lost capacity by various methods as:

By Ah - 17.45%
By 80% charge - 17.24%
By full charge - 18.85% (but may not be fully balanced)

with the CA leafs dropping a bar in winter months I'm expecting to see someone report a Feb loss in the next few weeks.

I'd also expect the March and April numbers to ramp up more this year than they did last year.

The suffering is over!! The car was back in my hands with a new battery on January 11th! Took the service department about three days to complete the work and Nissan corporate is VERY helpful after that fourth bar disappears. I'll be keeping this car after the lease is up and I'm hoping that the plan to provide certificates to get the new 'hot battery' to folks that fell under the warranty goes as planned.

55,773 on the odometer is about as good as it gets.
Did you have any inclination to go 59,000 before calling for replacement?

Was that hot voucher lip service or actually in the warranty?

Really nice to see that 12 bars again :D Now is time to join the 100 mile club if not already.

Will you charge or drive any differently with the new battery?

Nope, I'm back to my 'old ways' in the carpool lane baby!
