Leaving MBP for 6months - what to do about battery?

Hi All,

I am about to go away travelling for 6 months and will be leaving my year old 15" MBP behind.

I'm going to be storing it at a friends place, but am concerned about what might happen to the battery... can anyone offer some advice on what I need to do?

Cheers

Storing Your MacBook Pro
If you are going to store your MacBook Pro for an extended period of time, keep it in a cool location (ideally, 22° C or about 71° F) and do one of the following to preserve your MacBook Pro battery life:
Discharge the battery 50 percent before storing your MacBook Pro.
When storing your computer for longer than five months, discharge the battery to approximately 50 percent and then remove it from the MacBook Pro. If you are storing your computer for an extended period, recharge your battery to 50 percent every six months or so.

Long-Term Storage
If you don’t plan on using your notebook for more than six months, Apple recommends that you store the battery with a 50% charge. If you store a battery when it’s fully discharged, it could fall into a deep discharge state, which renders it incapable of holding any charge. Conversely, if you store it fully charged for an extended period of time, the battery may experience some loss of battery capacity, meaning it will have a shorter life. Be sure to store your notebook and battery at the proper temperature. (See “Notebook Temperate Zone.”)
