Abstract
The present invention relates to a charger and a method used thereby. Before being applied to charge an electronic apparatus, a pulsed discharge can be proceeded to a default value; after that, a battery can be charged by the pulse charging. During the charging process, the charger can determine whether the current exceeds a predetermined value; if so, the process will be switched to the corresponding charging stage to continue the charging so as to rectify the charging current; accordingly, the charger of the present invention can achieve a rather quick charging effect without damaging the durability the battery.
