Having driven a Brera for 5 years without anything going wrong (is this a record) I made the mistake of taking it off the road for the winter to avoid all that nasty salt and stuff. Despite regular runs the battery is now flat and won't take a charge. Expecting a few probs from here but I can't even get the battery off to check details to find out if I can get a proper replacement and avoid the Alfa price. Is the only way to remove the restraining strap the nut set down below the battery engine side? Anyone got tips for a reliable supplier?
