    I've got a Macbook Air (2012) and the battery needs replacing but looking at the health of the battery, it's only done 300 cycles.

    The apple support site says the battery should last 1000 cycles.

    Is it odd for a battery to be finished this early or typical of this model and 1000 is optimistic?

    I don't know if it is normal, but I replaced my 2012 air battery at around 300 cycles too, at 3 years of use. I have mine in clam book mode plugged in most of the time. There is some reference to having the battery plugged in at 100 percent charge all the time affecting the life of the battery. In any case, no big deal or big cost. My 2012 air is still my most used computer, and I see no reason to upgrade.

    It's a chemical component at the end of the day and subject to many environmental variables.

    So I installed Sierra and the battery status is now "good" instead of "needs servicing". The battery design capacity is at 60% though.

    Has anybody had any success getting the battery replaced under the 6 year consumer protection act in the UK?

    That won't work. The battery is 4 years old. No one will pay you the exchange.
