I just ordered an optima battery for my Jeep but my girls mustang needs a new battery. Can I just pop it right in and use it for the mustang? I have never done this before and it seems that it can be done.
Both are 3.8l engines I wonder how I can find that out. I'm going to google
The vehicle will tell you if the battery doesn't have enough amps......by not starting in cold weather, or sounding like it's cranking slowly. You should be fine as long as it fits under the hood properly.
