Hi I own a petrol 01 mk4 fiesta and on monday after the cold weekend the battery was flat and I needed a jump start. I cleaned the windscreen on the sunday so had the door open and the interior light on with the radio for about an hour. The bloke who came out said that I should buy a new battery the same day as it must be dodgy but I just drove it for about an hour to try and charge it up. Is it likely that with being 8 years old I need a new battery or should I get it checked for free somewhere first? It's started ok since. He made me sign to say that he's advised me to get a new one so does that mean if I break down again with the same problem the breakdown cover is invalid?
