A DC battery provides a constant current of I= 63mA.   Assume the battery started with a voltage of V= 11Volts at time t=0 and that the voltage provided by the battery decayed to half of its initial value after a time of  t= 149hours.  If the voltage provided by the battery decreased linearly over time, find the total energy provided by the battery over the 149 hour time period.  Express your answer in units of kJ (kilo-joules).
