I will be traveling in the near future for 5 to 6 months. Is it preferable to remove the laptop battery while it is in storage for that period of time ?
Apple recommends that you store the machine in a cool location with a 50% charge on the battery, and if you're storing it for more than 5 months, to remove the battery from the machine. (Good trick if you've got one of the recent machines without a user-removeable battery!) They also say you should recharge to 50% about every 6 months. See:
I agree with Thomas - I wouldn't recommend leaving a computer (or anything, really) without using it for more than a month. An easy way for problems to develop. Especially since I assume you have a MacBook, it would be very easy to take it with you 🙂
