That's a very good point. I suppose you could set a timer for 80%, and override it when you really want to charge, but that seems like a pain.

What about that month when it was sitting at 100%? Was it plugged in, and was there a timer that kicked in every night?

People are probably getting tired of me saying this, but please, folks, go check a dictionary. "Gradual" does not mean "slow". If you were losing 1% of your battery capacity every week, that would be very rapid loss, and you would be down a capacity bar in less than four months, but it would still be gradual. If you suddenly lost 10% of your capacity you would still have 12 capacity bars, but that would not be gradual. Gradual means "a little bit at a time." If the battery cells get weaker over time, that is gradual. If some cells suddenly fail, that is not gradual.

Sudden failure is covered. Losing capacity a little bit every day is not covered, no matter how fast it happens. I'm sure any court will uphold that as the proper interpretation of the word "gradual".

I would say that a 15% capacity loss in one year, and then a 15% loss in the remaining 6+ years would constitute non-gradual. AND, just to be fun, according to Lord Google, gradual does mean slow: Taking place or progressing slowly or by degrees. :geek:

I know it's already been said, but I'll echo the obvious to me. You did precisely what Nissan says is not good for the battery, and you did it in almost worst case conditions (hot).

The only thing positive I can say is that it wasn't 120F+.

I cycle my battery from 100% to literally turtle many times, and at 22,200 miles in one year, I still have virtually the same battery performance as new. But, my car is never exposed to Phoenix style heat, and it never sits at over 80% charge for more than a few hours.

I've been out of town for the past almost month, and my car has been patiently waiting for me at 50% charge in a cool garage with the 12 volt battery on a tender. The car is not plugged in to the Blink.

Heat is a killer to the life of these batteries, particularly when left at a high state of charge.

So, according to Lord Google, "slowly" is gradual; "by degrees" is also gradual. Therefore, Your Honor, if the loss happens slowly it is not covered. If it happens by degrees it is not covered. The Defense rests. :twisted:

Heat and high soc. not good these batteries

We will see most battery issues in these warmest states

Had the car just over one year. Over 20,500 miles and charge to 100% twice a day. Battery capacity is pretty much the same as it was when new.

Did you lease or buy

Good question for lease , let's say you are down 2 capacity bars or more by lease turn in

Guess its not damage, so you are ok?

It isn't just any heat that will damage the battery. You would have to leave it in 122 degree heat for 24 hours to damage it or like that one nss (I'm being nice) driver, QC it more than 6 times a day. That's the two worst things. Just the heat of AZ will NOT damage the battery. Leaving it at 100% for long periods will (doesn't matter if it is cool temps) and topping off above 80% will also. Those are the next worst for the battery pack.

So if you have no timer set and the blink turns off-on-off-on in the night you get several 100% charges?
I would assume if the timer was set there would be no issue because the timer would not start again once fully charged.
I would sort this out or dump that free blink that may cost you a battery.
1 bar lost at 21,451 miles, 16 months.
2 bar lost at 35,339 miles, 25 months.

RAV4 traded in for I-Pace Dec 2018

First off, the Blink will not charge if the timer is off on both the car and Blink. The Blink isn't the problem. It's all on how you set your timers. My advice is not to use the Blink timer, but to set your LEAF timer to the same time. For instance, I set my LEAF timer to 11AM and 11AM. Now, I can leave it plugged in for pre-conditioning as long as I remove the plug before 11AM. So overnight, it will not charge. It doesn't matter which times you choose, just choose two morning times the same. Also, with the timers set to the same time, anywhere you plug in, it will start charging.
