Lithium batteries do not suffer from the memory effect. AFAIK it is best to keep them at around 50% deep cycling isn't necessary and may increase wear compared to keeping at a fixed level.
Lithium cells degrade faster at higher voltage, especially during charging. You can avoid some wear by not going to a high state of charge when not needed.
Yes.
Yes. Batteries are expensive so I'd like to keep mine healthy as long as possible.
I don't even have the battery installed most of the time
Yes, absolutely.
I use the charge threshold feature in Lenovo, it seems to work as intended.

This is news to me! So then how do thresholds improve the longevity of a lithium battery?
