I've been quoted £51 to have a new battery fitted at my local Renault dealer. I am already a bit annoyed about the quote for the new battery - £117+VAT as I think that is a bit high. I'm wondering if they were taking advantage of me since I'm a woman.... I'm not a petrol head but don't mind DIY - is it not too hard to replace the battery myself? My car is a 2006 197 model.
