Is it possible that if you drain a battery all the way down, that it might not want to recharge? Maybe change the polorization... or remove it altogether?

Get 2 batteries (one is the bad one) hook them up with jumper cables. Hook up your battery charger. The good battery provides "flow" that "fools" the charger. Eventually it burns off the sulfates on the plates, and it'll start taking a charge (an old used car lot trick)

Shouldn't matter if they're hooked up Parallel.Have to remember that one... Quick question though, for clarification, do you hook the charger to the good battery or bad? I am thinking bad, correct?
Essentially, the resistance of the sulfates prevent the plates from taking a charge (this is a simplification, but its close to that). The addition of the extra battery allows "flow" of the electronic charge, effectively fooling the charger. I've even had 4 batteries hooked up in parallel for difficult cases. Now, agreed, the "recovered" battery hasn't the longevity of better conditioned ones, but it'll work temporarily (all a used car dealership needs is 6 months more)I don't see how connecting 2 batteries in parallel would force one to take a charge.
And what Scott said...a battery tender or battery tender junior are great ideas, cheap and will extend your battery life without any danger of overcharge.
I'm not going to get in a big discussion about battery fixes for dead batteries, I suggest some reading at manufacturers sites or some books on chemistry. A dead battery can reverse it's polarity and once a typical lead/acid starting battery has been fully depleted it's life is reduced.
