How many amps does a car battery need to start?

My mom and I got into an argument on how much power you need to run a car battery, so we decided to ask you! What’s the standard number of amps a car battery needs to start?

Answer
You’re asking in the right place! While the required power will vary depending on the type of battery you have, 400 to 600 amps should be enough to start your battery.
If your car is relatively small, you might not need more than 150 amps to get your car battery started. That being said, larger commercial vehicles may need as much as 1,500 to 2,000 amps.
