Speculation, FWIW:
If the 2014 LEAF really became OK to fully charge to 100%, that may have
been based on performance monitoring of the 2013 batteries not showing
degradation when charged to 100%. And that would imply that it may also
be OK to charge the 2013 to 100% regularly.
Or it may be because the EPA was rating the range based on the 80%
recommendation, splitting the difference between 80% ande 100% range,
and Nissan wanted a better number on the spec sheet.
Or both. Or something else.
What we do:
What we do with ours is charge to 80% most of the time. If needed
though, we don't hesitate to charge to 100%. We time it so that it
finishes the charge right before we drive so it doesn't sit at 100%
longer than necessary, to reduce exposure to any potential high charge
degradation.
It may be a good idea to charge to 100% until the lights go out every
now and then, so it can top balance the pack.
Also keep in mind that the entire pack capacity isn't actually used, so
100% is not the entire 24kWh. IIRC it uses about 21 kWh, which would be
just under 90% when charged to "100%".

Hi folks
In my 2013 leaf manual it says to not fully charge each cycle and only to 80
percent is preferred but in 2014 it became ok to fully charge. The chemistry
is the same NMC nickel manganese cobalt cathode with a lithium electrolyte and
a graphite anode. So did Nissan get it wrong? Is it ok to plug it in on short
15 mile trips each time? I do that on my Ghia that has 45k miles on LiFePo4
batteries and still ok equalize on each charge with balancers like the Leaf
does.
Best regards
