The short answer to your question is :YES. BUT it would be a very large battery. The typical annual energy consumption for my home is about 9,000kWattHours or 9 ,000,000WattHours At 9 volts that is 1,000,000AmpereHours A typical car starter battery is 50 AmpereHours So your hypothetical battery would need to be 20,000 times larger than the car battery Since a car battery occupies about 0.5 cu foot you are looking at a battery of 10,000 cu feet. or a 22 foot cube.
