My MP3 will be sitting in my garage for three months while out of town. Noone to start it once and a while. Should I disconnect the battery?

Has anyone used a battery tender? Any opinions would also help.

Why would you? I've left mine sitting out in a parking lot for that same amount of time while on excercise. Just give it a good wax. Your rotors will rust up a little and seize but once you get going, all is back to normal.
