How many watts are in a car battery?

My uncle says that you can use your car battery to run your refrigerator during a power outage. How many watts are in a car battery?

Answer
Your uncle sounds like a creative guy! For clarification, a refrigerator runs on watts, and a car battery runs on volts. We will need to use a little math to help answer this question.
Watts equals amps times volts. The average car battery is 12.6 volts with 105 amps. This would equate to 1,323 watt hours. So, your uncle is right!
You will need to shop for a car inverter. Find one that is at least 1,500 watts, and it will help you power your refrigerator for up to five hours—usually without damaging your car battery. Considering how much food we keep in our refrigerators, a $200 car inverter is a bargain!
If you live in an area that has frequent power outages, make sure you have the proper homeowners or renters policies in place. This is where Jerry can help!
