    When a macbook pro has low battery, it is meant to goto sleep, but instead my macbook runs out of power and dies. Is there a way to fix this problem so the computer just sleeps until I connect my charger and it becomes awake again?

    Any help would be greatly appreciated!

    I don't think it directly influences your problem, but before troubleshooting I would really consider updating OS to 10.9.3. Who knows, maybe the issue will simply disappear?

    I'd try an SMC reset and see where that gets you. http://support.apple.com/kb/ht3964

    Otherwise I'm seeing your cycle count is quite high on the battery (885) and it could just be a matter of an aging battery not working quite as it should. After all, 3+ years for a battery is fairly decent.

    Should I recalibrate my battery, would that help?

    Not too likely. The built-in batteries in the newer Mac unibody notebooks come pre-calibrated and do not require regular calibration like the removable batteries in older Apple notebooks.

    Mine started doing that shortly before the battery died. It would be a bit surprising in your case, since the status says "Normal", but at close to 900 cycles and what seems to be less than 80% of the original capacity left (the design capacity is 6900 mAh I believe), it seems your battery is approaching the end of its life.

    If you have AppleCare you can check whether you are eligible for a repair.

    A battery has plenty of life left after it drops below 80% health. I agree that if there is AppleCare coverage and it's below 80%, it makes sense to see if they will replace it free. However, a battery can continue to be used if the health is 70% or 50% or 30%, as long as it continues to hold sufficient charge to meet the needs of the user and doesn't show signs of swelling.

    Yes, I fully agree that a battery remains usable with 1k+ cycles and a lower capacity.
    However the OPs battery is showing some signs of malfunction (unless it is a software issue). I've had a few cases where I would get the "10 minutes left" warning and only seconds later the machine would just die, destroying any unsaved work. So if none of the above suggestions can solve the problem, a replacement might be a good solution.
