Swollen battery mid-2007 MacBook
OK so my MacBook is ancient but the battery has been fine up until yesterday. I've looked after it carefully and although it's been through many cycles (it's not installed right now and I can't remember exactly how many) it's still at 91% and was giving 3 or 4 hours of use. Yesterday it suddenly swelled up and I've decided not to use it as the MacBook won't sit flat with it installed. Does anyone know if the time limit for free replacement of these obviously defective batteries has expired? My guess is yes, given that the laptop is 6 years old, but I have also heard that there is no time limit for this particaulr issue. Anyone out there know if I can try for a free replacement? (I'm in the UK btw -- not too far from a store).
