The cycle life of a lithium-ion battery refers to the number of charge and discharge cycles it can undergo before its capacity declines to a specified percentage of its original capacity, often set at 80%. This metric is particularly important for applications where the battery is frequently cycled, such as in electric vehicles, power tools
The cycle life is the number of complete charge/discharge cycles that the battery is able to support before that its capacity falls under 80% of it''s original capacity.So if the battery is discharged to 60 % and then charged to 80% it isn''t a complete cycle.
