> If a battery can do 1000 cycles and remain above 80% capacity it is exempt

Is there a definition for a cycle? 80->85%? 33->72? 22-83? 87->96? Would each of these be a "cycle"?

A battery cycle is a full discharge/charge cycle (100 -> 0 -> 100). Going from 70% to 20% and then charging back to 70% is half a cycle.
