For most of li-ion batteries, a method of rapid charging has been adopted which will fill 80% of the capacity in a short time. Then it will be converted to the way of intermittent charging. For example, the apple laptop battery m9326g/a can reach 80% in about two hours if not in use when charging.


However, for all li-ion batteries, recharging cycles are limited. A recharging cycle is calculated by run out of all the power energy instead of a charge. For instance, if you play ipod for several hours with half of the power consumed and then recharged. It doesn’t mean that it has cost you a recharging cycle. If you do this again tomorrow, it is calculated as one recharging cycle instead of two. Each time a recharging cycle is finished, the battery capacity is reduced.
