To be fair, I am making the enormous assumption that we are 'storing' our battery when it's not in use. Which is not correct...? But it would be fairly safe to assume when not being used, keeping it around 40-60% is far better than keeping her fullIt looks like what I quoted, when following the associated link for associated issues, may just be for EV usage - they mention 3.92V being a threshold for graphite accumulation on anodes.
So I stand corrected - unless there are other issues for active usage vs. long term storage, but I can't find anything.
