> Within six months from receipt of the goods, you just need to show the trader that they are faulty or not as advertised. But, after six months in most EU countries you also need to prove yourself that the defect already existed on receipt of the goods, for example, by showing that the defect is due to the poor quality of materials used.

I have successfully used the EU consumer protection laws to have Apple replace a faulty battery on a laptop that was around 20 months old.
