Controllers will not turn on anymore

Weird red juice?  When you took the old batteries out did you clean out any corrosion and such?  If you cleaned it up well, tried new batteries and it still won't turn on, my guess would be that some of that stuff got in to the guts of the controller and fried it out.

Make sure it's as clean as you can get it and if that doesn't work, I'd say the controller is probably done for.

Yes but I still tried it with the other controllers who didn't have batteries at the time and they also didn't work

Do you have a friend that has a controller you can borrow to test and see if it works. To help narrow down the problem. (keep in mind you will need to sync the controller to your console)

You mentioned red juice coming out of a controller were the batteries were. Thats battery acid. I have come to think that maybe that has destroyed that controller...

I'm with agreement with Sage to Rage when it comes to the battery acid damaging the controller.  However for the other two that were not damaged, I would guess that the batteries are not making a solid connection with the controller.  Are you using the AA battery insert?  I have had problems with those myself in that while playing the batteries would not fit in snug enough and my controller would randomly turn off.

If that's the case I would suggest using an Xbox battery pack instead.  You can pick one up an official Microsoft one for about $10, or a third party one, such as Nyko, for a little less.  

okay I figured out what the problem was i was actually being a huge derp obviously. basically the one with the red juice which was battery acid was in fact dead, but it turns out that for one of my controllers, the part of the controller in which you put the battery's was broken so I must have been mixed up and used it on both the controllers, so technically I still have one working. Probably a confusing explanation but what count's is right now I can play, tomorrow ill fix the other one. Anyways THANKS

Glad you have figured it out :)

Unfortunuly that a problem in old models of 360 controls.

I know because i suffer that...

In the control in you encounter the juice try that last thing clean VERY WELL the contacts, whif a clean and dry cloth.

After that (i understand you use batteries right?)you have to go back to the past. (yes that what you think), you have to use back the "small" battery (like we call in brazil "pilha palito") in order to try fix that in new models of control that works and make the controls back to work without fails, but in the old ones that´s a lottery hour works and hours only work whif control conected in usb only!!!

I hope i help you and forgive my bad english it´s self learnerd.
