How long does it take to charge a car battery?

While leaving work last night, my car wouldn’t start. Fortunately, one of my coworkers gave me a jump start, and I made it home with no problem. However, I had the same issue this morning and had to get a jump from my boyfriend. He said I might not have driven long enough to charge the battery. How long does it take to charge a car battery?

Answer
Phew! You’re lucky people were around to help. It sounds like you may need a new car battery soon.
After getting a jumpstart, it takes about 30 minutes of driving to charge the battery enough to start your car. The battery will fully recharge after about an hour. The charging speed depends on how high your car’s RPMs are, so driving on a highway will charge the battery faster than driving on city roads or idling.
If you discover this is a recurring problem and driving for 30 to 60 minutes does not charge the battery enough to restart the car, you need a new battery.
Hopefully you have towing and labor coverage on your car insurance policy to avoid getting stranded. If not, consider a roadside assistance membership with Jerry.
Jerry’s roadside assistance membership offers traditional benefits like jumpstarts and towing, along with Uber-like tracking for the status of your service. Get it for as low as $4.16 a month.
