SpletP r indicates the power actually used relative to that which was available from the power source. This is not loss of energy, but represents non-use of available power (i.e., it means batteries have to be larger due to low P r values). Power factor values range from a low of 0.6 to a high of 0.9 and sometimes 0.95, which is highly desirable.
