    At 900 cycles at the moment. Just noticed the 'service battery' indicator when I click the battery menu on OS X.

    Quick question: Does the battery really stop working after 1000 cycles? Is it safe to continue using the laptop post-1000 cycles?

    I'm waiting for the Skylake rMB/rMBP to come out, so I'm not too keen on replacing my battery now.

    No, it doesnt stop working, but it becomes unreliable. You may experience random shut downs, since the battery suddenly runs dry, even though the OS reports a ~20% leftover charge. It will always keep working, just become worse and worse.

    The only thing that can happen is that the battery swells, but that is somewhat uncommon, and usually doesn't happen when the battery is kept in use regularly.
