   Discharging the battery fully before recharging may be called "deep discharge"; partially discharging then recharging may be called "shallow discharge". A "charge cycle" is not a unit of time; the length of time spent charging or discharging does not affect the number of charge cycles. [1] Each battery is affected differently by charge cycles ...

6. Capacity loss - Wikipedia

   en.wikipedia.org/wiki/Capacity_loss

   Capacity loss or capacity fading is a phenomenon observed in rechargeable battery usage where the amount of charge a battery can deliver at the rated voltage decreases with use. [ 1 ] [ 2 ] In 2003 it was reported the typical range of capacity loss in lithium-ion batteries after 500 charging and discharging cycles varied from 12.4% to 24.1% ...
