A charger includes a conducting member having a first end connected electrically to one of first and second contact plates on one of first and second clampers, and an opposite second end connected electrically to a charging circuit. The conducting member permits transmission of a reset signal to the charging circuit such that a switch controller of the charging circuit enables power to be sent from a power source unit to a battery through a selected pair of a first direction unit and a first switch, and a second direction unit and a second switch according to polarity connections of the first and second clampers to positive and negative electrodes of the battery when the first and second clampers clamp positive and negative electrodes of the battery.
