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% on a regular (near daily) basis. I’ve had a few cells prematurely die; like loosing 30-40% capacity (200Ah thunder skys). The others seem “okay”, but some are dipping lower in voltage under load, and probably have lost some capacity; I’ve been charging them up a bit with a single cell charger, as balancing at the top seems too rough on the cells. I’ve also got about the same mileage: 46,000. corbin > On Oct 4, 2016, at 7:19 AM, Mark Hanson via EV <ev@lists.evdl.org> wrote: > > 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.
