We’ve had several tries now at using the 2018 charging timer without success. We’re going to get to a place where we drive down to about 20% and then charge to about 80%. We’re missing something about setting the timers so suggestions welcome:

Here's what we do:
Turn on each day of the week

Set timer one to on

Set the start time for 12 am and end time for 4 am.
(for now, we don’t need to talk about whether that’s the right length of time)

Press the charger door open button and plug in.

Each time we’ve tried, it begins to charge immediately and goes to 100%

So as far as you can tell, is that a process that should work?

Edit:

Perhaps I’ve answered my question. Timer 2 was also set to on and timed from 12 am to 11 pm. I’ve set it to off. Next time we charge (about a week from now) we’ll see if we get the results we’re looking for. I wonder what logic is used by the LEAF when both timers are set to on.

I have replaced a 2011 with a 2018--yesterday.

The charge option of 80% charging is gone or how do I find it?
DId i miss something.

I read below, and it seems folks are still saying charging to 80% is best.

It has been gone since 2014. The easiest way to get to roughly 80% depends on how much you drive. I drive little, so L-1 charging, which adds about 2.7% charge per hour for me, is easiest. I just divide the % SOC desired by 2.7 and I get the number of hours to leave the car plugged in. If you drive more, then determine how much charge L-2 charging adds per hour. I also use free Quick Charging to get the car near 80% quickly, if I happen to be shopping near my local EVGo station and it isn't hot outside.

There is nothing wrong with charging to 100%, and it needs done regularly to keep the cells balanced. Just don't leave it at 100% for extended periods, especially during hot weather, and avoid charging during the hottest part of the day. For longest battery life, keep the charge level between 20% and 80% when the car is not being used.

thanks to all for the info.

Nissan guys told me that by 2013, Nissan had data showing the 100% charging was not an important factor in battery degradation; more like 80% wasnt a solution since folks mistreated the battery sufficiently in so many other ways.
as a result, they took out the 80% option,.

Nissan salescritters have told people all kinds of interesting things, from the 2011 Leaf having a 100 mile range, to the L-2 port being "Quick Charge", etc. They tell you what Nissan tells them, or they make something up, and they make it up quick, so to speak.
