A battery powered ignition circuit for internal combustion engines comprises an additional inductance, whose induced voltage at the instant of ignition of a spark plug in each cylinder is superimposed on the induced voltage of the primary winding of the ignition circuit inductance coil to cause a restrike of the arc between the breaker points to prevent the growth of a projection on the surface of the points of the breaker and, accordingly, to increase the durability thereof.
