The 2003 Ford Mustang is compatible with either a Group Size 58 or a Group Size 59 battery. It's recommended to choose a battery with at least 550 cold crank amps, which can be found at AutoZone or Walmart for prices ranging between $100 and $200, depending on whether you opt for an AGM type. Signs that it may be time to replace your battery include slow cranking of the engine, dim lights and other electrical issues, a lit check engine light, a visibly damaged battery, or if the battery is older than 3 to 5 years.
