    I heard the best way was to drain it down to 40-50%, then put it in a refrigerator. The cool temps help prevent degradation and 40-50% is the optimal charge for long term storage.

    Might want to check some other sources though as I am just going on memory. I know the 40-50% charge level is right, the fridge I am mostly sure about.

    The correct way is to keep it at 50%, turn the computer off and store it at room temperature.

    When you come back, leave it to charge to 100%. Leave it charging at 100% for 2 hours. Once completed, use your MBP until it drains battery completely, then leave it shut down for 5 hours. After 5 hrs, proceed to charge it again to 100%. Continue to use your laptop normally.

    This will help alot, otherwise your risk losing atleast 15-30 minutes of charge.
