You will not be able to discharge the battery enough to do much damage anyway, the battery cuts itself off when charge gets low enough to cause damage (0% isn't really 0%, but its the lowest relatively safe battery charge level). Cycling is how you train the battery to know how much juice is in it, to make sure your % is accurate (or else, as some of you have noticed, it will drain down to a certain % fast, then seem to take forever to go the rest of the way).
