I did a quick search but only found some info on nimh which I am not interested in. So if a lithium rechargeable 18650 battery shows data about charge cycles 100 the capacity is X, up to 200, 300 provides this other capacity etc, what constitutes a cycle? Is it only once you use up the battery and then charge it up from scratch? Or if I use 25% of the battery and top it up does that small topup classify as a whole cycle or would that classify as 25% of a cycle?
