The battery in a 2015 Chrysler 200 is located under the hood, but it’s not easy to see immediately. It’s tucked up by the driver’s side fender, behind the headlight assembly.
You can replace the battery yourself, but it’s a little tricky to get to. In some cases, the wheel and fender might have to be removed before you can get to it. If you’d rather not deal with hassle, you can always take your vehicle to a mechanic or Chrysler dealership to have the battery replaced.
