100% Charging?

[Becky50]

When you advise not leaving LEAF at 100% state of charge for too long, what do you mean by too long? Would 12 hours be considered too long?
Thanks,
Becky

12 hours every day is too much. 12 hours once a month is Ok.

If you have to charge to 100 percent frequently, I'd suggest either delaying the start of charge time so it finishes just before you leave or charge to 80 percent and push the timer
button off an hour or two before you leave.

The "end time" setting is a better way to minimize high-charge soak time. Set the charge to end just before your planned departure.

I know others here disagree, sometimes vehemently, but I'm taking the "don't worry, be happy" approach. I drive the car and plug it in when I get home. End of story. No fancy timers, no special precautions. So far I haven't lost any more bars that anyone else in my area with a similar age/distance car (2yr 26k)...

Going to do the same with the Tesla? Always range charge?

Thanks for the responses. I have been and continue to be very happy with my LEAF and this forum.

So it's not whether you charge to 100% that's damaging, it's how long you keep the 100% charge?

Anyone have any official info to back this up?

I believe the manual says not to store the LEAF at 100% charge for extended periods.
Otherwise it is the nature of Li-ion batteries to prefer more middle state to minimize degradation in storage.

This is different from automotive lead-acid battery that far prefers 100% charged during storage.

Not sure what specific lithium chemistry this was from, but there was a recent post on the TeslaMotorsClub forum with the image below.

Note that calendar life is best when stored basically empty and by far the worst when stored at 100 percent.

To clarify, if you need to go to 100%, do not set a start timer it should be clear but do set an end timer for just before you need to leave.
