Battery Life Calculator

We call a complete charge and discharge of the battery (charge to the battery's rated maximum charging voltage, discharge to the battery's rated minimum discharge voltage) a cycle, represented by Q. When the Q value of a lithium battery is 500~1000, its power storage capacity decreases. To the original 70% (some say 80% within the shelf life), this is what we often call battery life. Therefore, battery life is not directly related to the number of charges we often say. If you charge every time you use half of the battery, then the number of times you charge the battery is doubled compared to the number of times it is fully charged and discharged.
