Hi, with the Ford Fiesta (105 hp and 1796 ccm) my girlfriend’s battery is broken, now I wanted to buy a new one, but the one I could use was not there…. now my question, which battery can I still put in, at the moment is a battery with 60Ah and 590A in it? Some say the battery must be bigger the other smaller, what is right… thank you for every tip, important… it’s urgent!!!! Greeting Basti
