  It’s impossible to say, but if we assume it’s a typical Li-ion battery supplying 3.7V, then:

  9 kAh x 3.7 V = 33.3 kWh

  So, it would be enough to power the average American house (10 kWh/year) for 3.3 years, or 11.1 years for a typical European flat (3 kWh/year).

    I think your math is off given that just a typical US consumer full sized refrigerator can use ~650 kWh/year and still be considered Energy Star qualified.

    You are off by a factor 1000 on the household power consumption (I think these numbers are without heating or assumes that you don’t have electrical heating?). And the voltage could be anything on a magical battery ;)
