I got the logitec controller for christmas without any batteries besides the ones that came with it. Well needless to say those batteries died pretty fast after my christmas video gaming and i am about to go out and get some new batteries. My question to everyone is if those heavy duty batteries and the alkaline batteries are compareable. I heard those heavy duty batteries do not even compare to alkaline batteries but i wanted to come to those who know the most. What do you think should i listen to the advertiseing hype of the heavy duty batteries or should i go with the batteries that i have come to know and love and spend the extra money up front rather than over time?
