The uninterrupted battery operated generator system 50 of the present invention generates electrical and kinetic energy without using fossil fuel or external energy sources to recharge. It uses two sets of energy storage means 11, 12 alternatively, to power a rotational torque generating means 15. The rotational torque generating means 15 drives the rotational movement of a flywheel 31 coupled to gyroscopes 35, which store and multiply kinetic energy. An alternator 16 is driven by the rotational torque generating means to convert this kinetic energy into electrical energy. The flywheel 31 can also be fitted with a rail 42 engaging with a transmission roller 43 to transfer the kinetic energy via a transmission shaft 44 to a receiving system such as a vehicular or machinery transmission system. Some of the electrical energy generated can be used to recharge the energy storage means 11, 12, which have a charging time shorter than the operating time. A controller 10 connected to load sensor 19, voltage sensor 13, and frequency sensor 14 controls the power supply to the rotational torque generating means 15, thereby enhancing the energy efficiency, thus creating an uninterrupted battery operated generator system 50.
