A Tesla Model 3, for example, has a battery capacity of 50 to 82 kWh. Let's assume the lowest capacity of 50 kWh. A car battery is basically unusable long before it has lost around half its capacity. So 25 kWh. American households on average consume 10.6 MWh annually or about 29 kWh per day.

So an old Tesla battery still provides enough electricity to power an American household for nearly an entire day.
