Hey all,

I've got four different Xbox controllers that I use with my console/PC. All of them are first-party, but all of them are also second-hand. One of the controllers won't hold a charge and won't work unless plugged into the console via Charge Pack/USB cord. Another one won't hold a charge for very long, etc. What I'd like to do is just swap out all four controllers' batteries with fresh ones. Is there a place where I could buy four new batteries all at the same time? Would eBay be the way to go, or could I order them direct from Microsoft, or some other retailer? I just need the batteries. Thanks to anybody who can help!
