Is the Jeep Grand Cherokee a full-size SUV?

The battery in my car dies once and for all today. I had to walk to get a new one. I’m almost back now, but I just realized that this new battery might not have a charge yet. Do car batters come pre-charged? Or am I going to need a jumpstart?

I live in Chicago with my brother and drive through a lot of traffic on my way to work. I’ve been researching the pros and cons of electric cars, and I want to learn more about how the brakes work and if they are better than a car that runs on gas?

I haven’t had to worry about this yet, but something I think about a lot is what happens to airbags after you’re in a car accident. Can you use them again? Do they get replaced? Airbags are designed to be used how many times?
