Xbox 360 Controllers Issues

Recently I am having some issues with my xbox 360 controllers. I have 3 wireless controllers and sometimes they will connect and sometimes they will not, if they won't, it doesnt matter how many times I try to sync the console will not pick them up. I also have a charge and play kit, at the moment I have one of the controllers wired to the xbox, and I can turn on the xbox using the wired controller but then It sometimes will not register the controller.

Any ideas?

Yes, at the moment I have my main controller with no battery pack wired to the console because its the best chance of having the console recognise a controller
