Lithium batteries do not suffer from memory effect. They are best stored at about 40% for long term storage.

Deep discharge isn't absolutely necessary, and can damage a lithium battery. But they do have a life cycle, generally around 200 charge / discharge cycles.

Excellent answer. The only thing I might disagree with is the number of charge/discharge cycles. I think it's probably closer to double your number. It is dependent on how extreme the discharge and charge rates are. High rates will reduce the number of cycles (life). That's not so much of a concern with the discharge rate our cameras place on the battery. We have no control over this. Note that I'm talking about discharge rate, not level.

Personally, I try to swap batteries at, or not much below, the 20% level. That's probably a bit on the cautious side, but I always have plenty of batteries on hand. I never allow a battery to become totally discharged.

My Nikon batteries seem to have a better life cycle. My 18650 lithium batteries run a bit over the 200 cycle.
