Within the first 3 years of ownership I think. Otherwise they won't replace it free of charge.
I know of at least 2 colleagues in the UK who have successfully got batteries replaced after 4+ years using UK Consumer Law. UK Consumer Law covers 6 years from date of delivery with the burden of proof falling to me to prove my claim.
Apple clearly state the battery cycle and capacity and offer to replace it during their warrantee period. My battery has fallen short of the number of cycles / capacity statement that I consider part of the contract of the sale. So under UK Law they are obliged to resolve the issue.
I will find out next week when I go to my local store for a genius bar appointment. BTW I had AppleCare and within weeks of that expiring by battery performance dropped off from 83ish% capacity down to where it is now. Kind of sucks that the battery just made it over the line on AppleCare.

Lol. If the U.K. Law is such that you are entitled to a free battery after five years of use, it is no wonder the U.K. economy lags.
Let's see after this week if the US economy is doing much better; TRUMP TRUMP TRUMP ! LOL
