Abstract
There is described a charger and related devices, the charger being capable of charging batteries uniformly to a predetermined level by adjusting the residual electric amounts in the respective batteries to a uniform level prior to the charging operation, thereby avoiding overcharging of a particular battery or batteries. The charger ensures that a number of batteries be charged in a uniform electric amount or up to a predetermined level to preclude inverse charging of an undercharged battery or batteries which occurs when a number of differently charged batteries are used in series.
