Willie,

That's what happens when you use LifP04 cells. You never know when a cell
will go south for no reason. I have about 75 customers including my own
conversions using NEW Volt cells and have NEVER had a bad cell in over 5
years. Who else can say that. Cannot vouch for those who buy used batteries

Yeah, I don't know why they would change their recommendation; people
might have been complaining about the limited range when only charging
to 80-90%.

If that's the case I wonder why Nissan dropped the less than 100% requirement
from the newer 2014 and up vehicles? I guess I don't understand why fully
charging and equalizing the cells would hurt battery life. Maybe just a hang
on from the lead days :-).

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
Are you sure the 2013 cells were the same chemistry? I thought they were the
older spinel type, not NMC.
Anyway, worst case for decreasing cell life is high voltage and high
temperature as shown by Dahn and other researchers, so most manufacturers
recommend not charging to 100% SoC regularly. I hav
Lithium cells (of all chemistries) seem to have the fastest degradation when
they are charged to 100% on a regular basis. The general consensus is to keep
it in the 20-90% range. This is also what Tesla recommends for the Model S / X.
I’ve also been charging my LiFEPo4 cells in my VW bug 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 i
