Not worth the investment, I don't play alot of xbox, and after about a month or two you need to have your controller plugged in at all times. Some people reading this might think I just don't know about battery memory, but I'm not a kid.. I know you need to drain it's life before charging it each time, but I only got to recharge my battery pack twice back to full from empty and it wouldn't store a charge anymore after that. I only got to charge it twice.. You can buy a bundle pack of batteries for half the price that'll last you a year or more depending how much you play. If you don't mind playing with a wire, sell your wireless controller and you can buy two WIRED xbox 360 remotes brand new (I got one for $18 at a store in person) and you never have to buy batteries..
