Removing the Battery for Extended Periods

I've stored my car for the winter and unfortunately I can't leave it on a tender. My options are: run the car once every few weeks, or remove the battery completely and put it on a tender.

Could someone PLEASE give me a concrete answer as to the repercussions of removing the battery for an extended amount of time (5-months)? I've read a lot of scare stories about the computer going mental, but other than resetting the clock and windows, is there REALLY any concern about doing this?

If it helps, I have a eBay BMW Specific OBD cable, so can I make a "backup" or something??
