ABSTRACT:
A counter electromotive force prevention unit for batteries is provided that can prevent occurrence of noise due to the counter electromotive force generated by loads of a battery and turning on and off of the charging generator, that can suppress noise emanating from the car audio speakers which are electrical equipment and malfunctioning of electronic equipment, and that can be easily attached to an existing battery. A blocking diode (104) and a fuse (105) that fuses with overcurrent are serially connected between the positive lead wire (102) and negative lead wire (103) that are respectively connected to the positive terminal and negative terminal of the battery which is the direct-current supply source, and a capacitor (106) is connected in parallel to the blocking diode (104).
