It's almost 15 years ago now, but I found Apple (or at least staff in the London Oxford Road Apple store) to be very responsive when the battery for my perhaps 3 or 4 year old MacBook Pro expanded and broke. I think there may have been a recall (which had expired by that point) but on bringing it in the staff member just unboxed a new £100 battery and sent me on my way. Various employers have purchased maybe 5 new Apple laptops on my behalf since so probably a good call.
